I've actually get a few issues. Here's a list of them, and hopefully some of you locations guru's can help me out!</p> <ul> <li>Currently I have CCK_gmap_address installed, and I am using this in the nodes I want to display in gproximity. I got gmap_latlon, for enabling field views for the lat and lon based on cck_gmap. It works and what not, but Gproximity will not recognize the fields for some reason. Anyone got any advice or experience working with this?</li> <li>As a work around, I decided to put a location field in as well, based on the location module. Shortly after putting an address into a node however it dissapears and is no longer there when you next edit it. Where did it go? Wtf mate?</li> <li>When I create a view for g-proximity, I can select a wide variety of location fields. I select of course location: lat, and location: lon. Are these fields from the nodes location field I am filling out, or am I doing something wrong?</li> </ul> <p>There may be some information I neglected to include that you need. I appologize if that is the case. I'll gladly get more specific as nescessary. Thanks everyone, and I would love to get this information from you all. Upon doing some research and asking this question in another location (The Portland Oregon drupal group) I discovered there are others encountering similiar issues/questions, so what you share with me will surely be passed on in a most grateful manner.</p> <div class="og_rss_groups"><a href="/mapping">Location and Mapping</a></div> http://groups.drupal.org/node/15654#comments Location and Mapping Tue, 07 Oct 2008 08:46:17 +0000 jnicola 15654 at http://groups.drupal.org http://groups.drupal.org/node/15569 <p>You are invited to attend Drupal Camp Chicago on October Friday 24 &amp; Saturday 25 2008.</p> <p><a href="http://drupalcampchicago.org" title="http://drupalcampchicago.org">http://drupalcampchicago.org</a></p> <p>Who/Why:</p> <p>For over 2 years Chicago Drupal has truly highlighted the benefits of an open source initiative.

It is dependant on the GMap module. It provides a CCK Field to enter an address and display it in a GMap. Therefore GMap is used to get geodata (lon/lat) validate the address and display the GoogleMap. Data stored in the field are lon, lat, accuracy and the address string. Display of the GMap can be customized per field (e.g. for teaser,full, views display).<br /> At the time I built the module, there wasn't any that satified my needs on such a CCK Field.</p> <p>In the near future I want to expand the features of this module. Because there are a lot of GMap/Geolocation modules with a lot of different features, but also al lot of common ones.<br /> So I first want to present my planned features. <strong>In second I want to initiate a discussion on this module and other existing modules, dealing with the same aspects.<br /> My ambition is to cooperate with other module mantainers and programmers, to build a more efficient way of implementing Geocoding in Drupal, especially as CCK Field.</strong></p> <h3>My planned features:</h3> <ul> <li>Second Widget to fetch address data from different existing Fields (like cck textfield, taxonomy)<br /> ** on the fly/cron geocoding for this widget, to be able to add GMap to an existing site, withput saving every node</li> <li>Display route in embed GMap</li> <li>GMap Views implementation (also gProximity?)</li> <li>Radius search - Views and/or search implementation</li> <li>improved Documentation</li> </ul> <p>I did test a lot of modules, but that was some weeks ago. So I could need some help on planning future features or some hints to existing<br /> modules.<br /> If you are a module mantainer, you are welcome to contact me ;)</p> <p>Edit:<br /> For bringing existing modules together (especially in CCk matter), I think of building a base cck field that stores data like (lan, lot, street,...), and provides different Widgets for typing an Address, mark a place on a GMap, etc. pp. .</p> <div class="og_rss_groups"><a href="/mapping">Location and Mapping</a></div> http://groups.drupal.org/node/14666#comments address CCK geolocation gmap location Location and Mapping Mon, 08 Sep 2008 17:44:30 +0000 derhasi@drupal.org 14666 at http://groups.drupal.org http://groups.drupal.org/node/14430 <p>Hi Guys</p> <p>I have been trying to build a site that takes in user data through CCk fields and then displays that information on google maps . I have been using CCK, gmap, geonames, location and views modules. I have been playing around with it for the last 2 weeks and have been unsuccessful. Which has lead me onto trying to find tutorials on how somebody would put such a website together.

Please if anybody knows where i could find some information, would be greatly appreciated.</p> <p>Tom</p> <div class="og_rss_groups"><a href="/mapping">Location and Mapping</a></div> http://groups.drupal.org/node/14430#comments CCK geonames Google Maps location mapping Location and Mapping Sun, 31 Aug 2008 16:35:19 +0000 reachtommy 14430 at http://groups.drupal.org http://groups.drupal.org/node/14134 <p>I've had some time and some funding, so I've roughed in my proof of concept on a D6 version of Geo. In traditional geek style, the most informative descriptions are in my commit messages: <a href="http://drupal.org/project/cvs/147736" title="http://drupal.org/project/cvs/147736">http://drupal.org/project/cvs/147736</a></p> <p>Basically, my goal is to demystify "geospatial", while integrating it as much as possible within Drupal. It needn't be an academic exercise to get this data working properly, so I've tried to keep things simple. The goals/implementation do the following:</p> <p>1) Provide an API module, which makes available some functions such as geo_db_add_field, and others. It also keeps track of the capabilities of the various installed backends, and provides some Views 2 handlers.</p> <p>2) Provide CCK fields that can contain geospatial data. The use case here would be to store user-generated data such as points ( e.g. addresses ), lines ( e.g. an uploaded track ), or polygons ( e.g. a hand-drawn shape ). I have rearchitected this from the original implementation so that it now works closely with CCK itself. Basically, you let CCK create your field's table, and then we sneak in and add a geospatial column.</p> <p>3) Import externally-provided shape data, and make it work in harmony with Drupal's existing data. I wrote an import utility this week so that you can download zip files from any source, and upload them to your Drupal site (!).</p> <p>4) Using the imported data: You can create CCK fields that match a name/value pair from the column, for example "state id/state name", and users can add data using select lists. This key is then used to link your content to the imported geospatial data, so that your queries can use Contains, Within, etc. functionality.</p> <p>While somewhat crufty and fallible, this code is all pretty much in working order. I'm working on this project in conjunction with <a href="http://drupal.org/project/votesmart" title="http://drupal.org/project/votesmart">http://drupal.org/project/votesmart</a> , and using Geo to find district- and precinct-level data based on a user's address. I can import legislative district data from census.gov, automagically create content types for candidates using Vote Smart, assign them a district ( e.g. 61A ), and then search for representatives using Views filters.</p> <p>As long as you're cool with typing "POINT(-94.14796237931 46.438258841379)" into your exposed filters, it's working pretty well ;)</p> <p>I'm seeking input and developer-level feedback. It's by no means ready for end users, but I'm interested in extra pairs of eyes at this point.</p> <p>Thanks, see you next week!</p> <p>Allie</p> <div class="og_rss_groups"><a href="/projects-needing-financing">Projects Needing Financing</a></div> http://groups.drupal.org/node/14134#comments Drupal for Good Location and Mapping Projects Needing Financing Wed, 20 Aug 2008 19:49:39 +0000 Allie Micka 14134 at http://groups.drupal.org http://groups.drupal.org/node/13951 <p>Hi folks, I found the countries_api module the other day as a replacement for the internal ubercart 'geocoding' functionality. I'm thinking after some more research that the location or address module would be a better use of time.</p> <p>However, both of these modules are incomplete when it comes to full country code information. I'm thinking it'd be a good idea to abstract out the country information that currently exists in the .inc files. Discussion a few years back on some other mailing lists made an XML file similar to the following:</p> <p><a href="http://pastebin.com/fe4426fa" title="http://pastebin.com/fe4426fa">http://pastebin.com/fe4426fa</a> --&gt; XML schema for country codes</p> <p>I think this would be very useful to implement for the location and/or address module, then bring an nice API together so modules like ubercart and ecommerce can grab country / region / address information without needing to create their own data.</p> <p>Optionally, we also need to add a field for address format, since each country seems to be a little different. Ubercart has a definition for the 'address-format' field above here: <a href="http://www.ubercart.org/docs/user/303/country_settings" title="http://www.ubercart.org/docs/user/303/country_settings">http://www.ubercart.org/docs/user/303/country_settings</a><br /> It didn't look obvious to me, but perhaps the module already has this support?</p> <p>I'd much rather integrate these features into a pre-existing module. Ideas?</p> <div class="og_rss_groups"><a href="/mapping">Location and Mapping</a></div> http://groups.drupal.org/node/13951#comments countries geocode xml Location and Mapping Wed, 13 Aug 2008 18:35:39 +0000 japerry@drupal.org 13951 at http://groups.drupal.org http://groups.drupal.org/node/13581 <p>Hi everyone.

CiviCRM already has some mapping features, but it is not as extensive as GMap. So one direction we are going in is to try to bring CiviCRM data towards the Drupal side and integrate it into GMap. Right now, the main feature is that this module builds KML feeds that can easily be an overlay on a GMap Macro (with the help of GMap Addons).</p> <p>You can download and try it out, but it could change drastically at any moment at this point in its life, so I make no promises. What I need form you is some feedback on what you might want this module to do, and how it would most benefit the community as a whole.

The plan is to store user location and their commitments in Drupal. Then the existing JavaScript could be refactored to fetch the data from Drupal instead of the current had-hoc backend. After some research, it seems that the best solution to add (optional) information to user profile is to the <a href="http://drupal.org/project/content_profile">Content Profile</a> to create a "Profile node" for volunteering users. This node would have to provides a means to store user location.</p> <p>So what I need is<br /> 1. Store the addresses (a) and lat/long (b) of the user in the node.<br /> 2. Retrieve the list of all users in a JavaScript parsable way (JSON, XML or even plain XHTML with microformats) filtered by some fields (not the location themself).<br /> 3. Optionaly, refine 2. so that users can be searched by location too.</p> <p>Point 1.a can easily be done in a ''profile node'' using the <a href="http://drupal.org/project/addresses">Addresses</a> module. For point 2. there seems to be some possibility with the <a href="http://groups.drupal.org/services">Services modules</a> but it clearly depends on the feature provided by the modules used to achieve the first point. Point 3 can wait, the only requirements is that the solutions for 1 and 2 must be not lead to at dead end regarding this goal.</p> <p>So I'm currently searching a clean solution for 1.a as I did not found any module that let me store the lat/long (I'm working with Drupal 6). The only solution I see is to develop may own little module to store the lat/long (either as an Addresses extension or as a simple CCK module). But it seems like a waste of time (and I don't know a lot about Drupal development, I'll have to learn). I would better use the little time I have contributing to a widely used module. I don't have a lot of time, nor does I have experience with Drupal, but I'm pretty experienced with PHP and JavaScript.</p> <p>Does any one see where I can help and contribute while also working towards my goal ?</p> <div class="og_rss_groups"><a href="/mapping">Location and Mapping</a></div> http://groups.drupal.org/node/13507#comments geolocation json user-location Location and Mapping Mon, 28 Jul 2008 18:56:55 +0000 mongolito404@drupal.org 13507 at http://groups.drupal.org http://groups.drupal.org/node/13364 <p>I just found this....

Each point must hold at least a relative distance from start. Altitude, latitude/Longitude and userdata are optional. Lat/lon are strangely optional, but did this for people who have a cycle computer for instance that only records distance and altitude - they can still use the CCK field to store and plot this data. I have the idea that userdata can be things like speed, heart rate, cadence, time, etc, etc. At the moment there is a formatter to plot distance/altitude graphs. It can normalise data to show multiple fields/nodes on the same graph if required. Adding userdata to the graphing capability is high on the list. No map is shown at the moment, although a KML export (see below) will make inclusion of Google Map trivial.</p> <p>There will be a second field type that will store derived statistics from the first. Things like total distance, max speed, average gradient, etc. Such stats have to be in separate fields to be used in views (well - to use in view and avoid too many formatters anyhow).</p> <p>I didn't see the need to have something to store single points - users can enter nodes at specific locations using current location functionality of course.</p> <p>With the above, the KML module can be extended to include paths entered into this type of field.</p> <p>I planned to have KML/GPX/CRS/HST (CRS &amp; HST are Garmin course/history exports) import at some point (at the moment am creating the arbitrary sets of numbers required with a perl script). Other functionality that is here now though, is the ability to extract data sets from existing fields and have created a graphical JavaScript pop up for this. This allows trimming of a current node. Joining/cutting/adding from/into nodes could also be done with a similar tool without too much bother.</p> <p>How this can be used is: when a user wants sets of points in a path though they can create a node type using the above CCK fields. As many derived fields as are required can be added. In fact, maybe the derivation module should have hooks so that it can be extended. Ie, someone stores userdata set of 'foo' they create a module that knows how to average 'foo' and how to work out some other stat based on 'foo' and distance.</p> <p>Your idea of using WKT is interesting, but it seems to go beyond what we are looking for. For example, to just draw a graph of distance/altitude. WKT seems to be able to input many points and paths in a single field (or node) so in that case how could you relate these?</p> <p>Sorry for the long edit, good ideas. I hope to have my code ready for general consumption and a demo very soon.</em></p> <p><em>Grugnog: not sure if these should really each be separate projects - there are a LOT of countries in the world, and a lot of sites really want anyone in the world to be able to enter an address! Is there not a more lightweight setup that could be used (e.g. .inc files)?</em></p> <div class="og_rss_groups"><a href="/mapping">Location and Mapping</a></div> http://groups.drupal.org/node/9665#comments Location and Mapping Tue, 11 Mar 2008 21:26:13 +0000 Bevan@drupal.org 9665 at http://groups.drupal.org http://groups.drupal.org/node/9612 <p>I think that one of the reasons there are so many competing / non-collaborating solutions is that it's really hard to see past our own use cases into a more general focus. I think it would be a big mistake to build an ever-expanding collection of fields to input geographic data, and to try to imagine other cases.</p> <p>It's also trouble to worry too much about street addresses. There's a large - and increasing number of use cases for locative data that have nothing to do with addresses: Point data for a geocoded photo or the presence of a marker (e.g. "landmine"), line data for an uploaded track, an area representing a particular precinct or zipcode, and so-on.</p> <p>Meanwhile, data entry is in parallel with other types of data entry. Take, for example:</p> <p>1) I'm a user and I want to upload a photo with geocoded exif data. I'm already familiar with the image upload UI, and there's no compelling reason to duplicate all of that data.</p> <p>2) I'm a user and I want to update an address. I don't know/care about this geocoding stuff. I also have lots of reasons to enter addresses which are not necessarily on a 1:n node:address relationship. For example, my user profile has an address,</p> <p>3) I already know coordinates, and I simply want to enter them into decimal fields. Thankfully, CCK already provides me with the capability to enter, validate and store this information. I shouldn't need a parallel UI.</p> <p>4) I'd like to upload a GPX file from my device's track log. That's just a file, right? I upload files all the time.</p> <p>5) I'd then like to upload non-encoded images, and set their nodereference back to my GPX-track-enabled node. Based on a little timestamp-alignment, my photo should be geocoded without my lifting a finger.</p> <p>In all of the above cases, we have preexisting field work: ImageField, Location/Postal/Address/..., CCK's Number field, File API, NodeReference. These are receiving ongoing attention and security/usability improvements, and are already in a site manager's toolbox. We should be able to transparently convert these fields into meaningful GIS data, without messing with the content contributors' existing practices.</p> <p>Thus, I propose we focus on a) geographic data storage and searching, and b) bridging to existing field types - with one pluggable, field-based module.</p> <p>The administrative workflow should be subtle - we write connecters to various field types ( e.g. a geocoding bridge for the/a postal field, an exif-reading bridge for image fields, a GPX-parsing bridge for file uploads, and so-on. )</p> <p>Rather than introducing new chrome to the mix, we can simply add a 'Store geographic data' checkbox on the field-wide settings for any field whose type has an available bridge.</p> <p>The module then proceeds to stalk the updates/changes to the field it has attached to, making respective changes in its own storage backend.</p> <p>By "the module", I'm generally referring to Geo, which means that by switching this single module on, you can instantly enable pre-existing fields to begin storing GIS data for Views and output formatters.</p> <div class="og_rss_groups"><a href="/mapping">Location and Mapping</a></div> http://groups.drupal.org/node/9612#comments Location and Mapping Mon, 10 Mar 2008 21:58:09 +0000 Allie Micka 9612 at http://groups.drupal.org http://groups.drupal.org/node/9557 <p>Hello everyone!</p> <p>I would like to apply as a student for the summer of code.

It's missing a few details no doubt, but in addition to the already open components listed here, EveryBlock (funded by the <a href="http://knightfdn.org/">Knight Foundation</a>, which is also making significant investments in <a href="http://boston2008.drupalcon.org/sponsor-list">Drupal</a>) will ultimately make the complete recipe available. Here's the parts they're using:</p> <blockquote><p><em>For the technology-inclined reader, here&#8217;s how we put our map platform<br /> together. All web technologies are a &#8220;stack,&#8221; like layers in a map, and our map stack starts at the top with <a href="http://openlayers.org/">OpenLayers</a>, which<br /> provides the click&#8217;n&#8217;drag&#8217;n&#8217;zoom interface. The next step down in the<br /> stack is <a href="http://mapnik.org/" title="Mapnik C++/Python GIS Toolkit">Mapnik</a>, which renders geospatial data into graphical images. At the bottom of the stack is our collection of geospatial<br /> data, which includes <a href="http://www.census.gov/geo/www/tiger/index.html" title="TIGER®, TIGER/Line® and TIGER®-Related Products">TIGER/Line</a> and shapefiles from various city<br /> governments, as well as databases and tools that operate on that data, such as <a href="http://postgis.refractions.net/">PostGIS</a>, <a href="http://trac.gispython.org/projects/PCL/wiki/Shapely">Shapely</a>, and <a href="http://www.gdal.org/ogr/" title="OGR Simple Feature Library">OGR</a>. Finally, the &#8220;secret sauce&#8221; layer in the stack is <a href="http://tilecache.org/">TileCache</a>, which actually sits between OpenLayers and Mapnik. It provides caching of the map tiles that are generated by Mapnik and served to OpenLayers. I say &#8220;secret&#8221; because it&#8217;s transparent to both the layers it sits between, and also because it greatly speeds up the entire stack, making it possible to deploy and scale a large mapping application. It&#8217;s worth mentioning that all these layers of the stack are open source or licensed freely. If you can build and deploy a web application, you can build and deploy a complete standalone geospatial and mapping application. The tools and data are there for the taking.</em></p></blockquote> <p>How much could/should make it into Drupal? And of greatest interest to me, what can Drupal developers and deployers do to encourage the creation of shared information resources of new mapping information? (For instance, the location of all Drupal meetups, contributed by many sites and shared among them?)</p> <p><strong>UPDATE:</strong> This DrupalCon Boston <a href="http://boston2008.drupalcon.org/session/drupal-gismapping-platform">session proposal on Drupal as a GIS/Mapping Platform</a> means Drupal reality is, as usual, ahead of my imagination.

Ignore the form_alter stuff at the top; this was when I was thinking it was going to be its own form element but Eaton advised me to go with CCK field instead (user form would be possible w/ something like Bio module).</p> <p>I basically need to ping $geo_service on form submission with whatever fancy API they offer and then store the entered text, longitude, and latitude. Then display the output through $mapping_service.

I proposed that we add an event type vocabulary, which allows events to be tagged as being of specific type. Let's collect the list we are interested in having for events:</p> <ul> <li>User group meeting</li> <li>Regional conference</li> <li>International conference</li> <li>Virtual meeting (IRC meetings, Drupal dojo)</li> <li>Training</li> </ul> <p>Anything else I am missing? This would allow better targeting of the entered information so people can subscribe to training feeds, or can get informed about a bigger conference in advance.</p> <p>Now the next step is to be able to restrict to events happening around us in real life, that is: adding location information to events where it makes sense (ie. everything except virtual meetings). While event categories are easily done with taxonomy, what can we do about location information? How can we collect this to be able to target users with events happening close to them and still being easy to enter? How can we plot this information on a map?

Please help rewrite and expand the document to describe how things actually work in 5, and I'll commit them to CVS. </p> <pre> ===============NOTE!!!!=================== This is the 4.7 documentation, and has not been properly updated for 5.0 yet! Most of it is misleading or wrong! If you run into issues, the issue queue or IRC are usually the best places to go for help. ========================================== ------- STUFF BELOW THIS POINT HAS NOT BEEN REVIEWED YET!------- ------- PLEASE DO NOT TRUST THIS DOCUMENTATION!---------- ========================================== GMAP API DOCUMENTATION The GMap API is a simple way to create Google Maps from a macro or PHP code. ========================================== CONCEPTS The gmap API allows other modules to integrate Google Maps into their Drupal site. It can also be used by theme developers to integrate Google maps into portions of their theme. It can also be used to insert a map into any block of php. ========================================== PROGRAMMING API There are two different methods of inserting a Google Map using the gmap API. The first is using a macro as can be built from the macro creator included as part of this module. The second uses the gmap associative array to define the Google Map function. ========================================== I FIRST METHOD: Macro [Please note that there is discussion going on of moving away from filter/macro concept. (see here: <a>http://groups.drupal.org/node/4323</a>)] Macro is basically a short text tag, that you can insert into your node content. When the node is displayed then a Drupal's hook_filter() invokes GMap module and replaces this tag with Google map. There is GMap Macro Builder module in order to build macro tags easily. An example of Macro tag is: [gmap markers=small red::49.468124067331644,0.17578125 |zoom=5 |center=52.10650519075632,-0.8349609375 |width=580px |height=480px |control=Small |type=Map] The syntax of Macro is the following: the variables are separated by a "|" and then uses an "=" to define that variable. Possible parameters are: id - the id for the map. Each map on a page must have a unique id. center - The comma separated latitude and longitude of the centre of the map. width - width of the map height - height of the map zoom - the zoom factor of the google map align - the alignment of the map 'right', 'left' or 'center' control - the control shown on the map 'Large', 'Small', or 'None' type - 'Map', 'Hybrid' or 'Satellite' points/markers - a string of points to mark on the map with + between each point line - the line is defined by a set of points separated by a + track - Draws a line based on the points in the .plt file feed - the RSS feed with geo:lat information to be parsed by js The following shape types require XMaps: (xmaps is not currently functioning) circle - a circle based on a center point and a radius in km separated by a + and optionally can include the number of sizes. rpolygon - a regular polygon is defined by the center point and a point on the permiter separated by a + polygon - a polygon is defined by a set of points For a more detailed explanation on how to make complicated macros see: <a href="http://webgeer.com/gmapdemo" title="http://webgeer.com/gmapdemo">http://webgeer.com/gmapdemo</a> You can convert a macro into a GMap array with the function gmap_parse_macro($instring,$ver=2) $ver is only required if you need to use a macro generated with an old version of gmap where the format was longitude, latitude (set to 1 in that case). The GMap Array is an associative array with the following definitions: id - the id of the map every map on a page must have a unique id width - width of the map should be either 'px' or '%' height - height of the map latitude - a string of the latitude of the centre of the map longitude - a string of the longitude of the centre of the map zoom - the zoom factor of the google map align - the alignment of the map 'right', 'left' or 'center' control - the control shown on the map 'Large', 'Small', or 'None' tcontrol - whether the type control is on the map or not: 'off' or 'on' scontrol - whether the scale control is on the map or not: 'off' or 'on' ocontrol - the 'width,height' of the overview map control type - 'Map', 'Hybrid' or 'Satellite' drag - 'yes' or 'no' map is draggable. Default is 'yes' markers - an array of marker arrays. Each marker array is an associative array with the following elements: 'latitude' - the latitude of the marker 'longitude' - the longitude of the marker 'markername' - the marker icon to use. For example if it is set to 'number', then the icons in the marker directory named 'number1.png', 'number2.png' etc. will be used. If these don't exist 'number.png' would be used. If that doesn't exist then the default marker will be used. (optional) 'text' - html text to be located in a pop-up window when you click on the marker. (@@@ Describe array tabs trick... --Bdragon) shapes - an array of shape arrays. Each shape array can have the following elements: 'type' - 'line', 'circle', 'rpolygon', or 'polygon' 'color' - the hex for the color to create the line (eg. '#00dd00') 'width' - the width of the line in px 'opacity' - between 0 and 1 for the opacity of the line 'pattern' - a broken line definition '20 5 10 5' would mean 20 px long line, 5x break, 10px line 5px break 20px line ... (xmaps objects only) 'text' - the text used in the line (xmaps only) 'fillcolor' - the fill color for filled objects (xmaps objects only) 'fillopacity' - the opacity of the filled objects (xmaps object only) tracks - an array of track arrays. Each track array can have the following elements: 'filename' - a filename for the track (.plt) file. Should be relative to the drupal base url. 'type', 'color', etc... same as the shape line. feeds - an array of feed arrays. Each feed array can have the following elements: 'url' - the url of the feed. 'markername' - the marker icon to use. same as for markers except that numbered markers are not supported. wmss - an array of WMS services arrays. Each WMS service array can have the following elements: 'name' - the name of the custom map (no spaces or special chars). 'url' - the url of the WMS service. 'format' - image format to retrieve. Depends of WMS service: 'image/gif','image/png','image/jpeg' 'layers' - a comma separated list of layers advertized by WMS service to show in this custom map. 'minresolution' - lowest zoom level of this custom map. 'maxresolution' - highest zoom level of this custom map. 'copyrights' - an array of copyrights to display. Each copyright array can have the following elements: 'minzoom' - lowest zoom level at which this information applies. 'bounds' - a comma separated list of coordinates defining a region to which this copyright information applies: 'S,W,N,E' 'text' - text of the copyright message. 'overlaywith' - (optional) overlay WMS layers with this Google layers: 'Map', 'Hybrid', 'Satellite' or 'None'(default) 'merczoomlevel' - (optional) zoom factor of the google map where WMS service should advertize layers in Transverse Mercator projection instead of WGS84 projection.

Insert a map into a theme, the complex way: <div class="codeblock"><code><span style="color: #000000"><span style="color: #0000BB">&lt;?php<br /></span><span style="color: #007700">echo </span><span style="color: #0000BB">theme</span><span style="color: #007700">(</span><span style="color: #DD0000">'gmap'</span><span style="color: #007700">, array(</span><span style="color: #DD0000">'#settings' </span><span style="color: #007700">=&gt; </span><span style="color: #0000BB">gmap_parse_macro</span><span style="color: #007700">(</span><span style="color: #DD0000">'[gmap |id=map1 |width=120px .... ]'</span><span style="color: #007700">)));<br /></span><span style="color: #0000BB">?&gt;</span></span></code></div> ========================================== GMAP HOOKS &amp; FUNCTIONS There is one hook (hook_gmap) and some useful functions provided by gmap.module API: ---------------------- hook_gmap($op, $map=null); * * This is implementation of hook_gmap(). * * $op can be: * * 'behaviours' -- use this hook, if you need to affect the default behavior of the map. * * 'pre_theme_map' -- use this hook, if you need to load your own custom js. * * 'macro_multiple' -- use this hook, if your custom module needs to add/affect list of * elements that can appear multiple times in the map. * In default the hook_gmap('macro_multiple') returns array: * array('points', 'markers', 'feed', 'circle', 'rpolygon', 'polygon', 'line') * * 'macro' -- By default the hook returns array ( * points =&gt; array('multiple' =&gt; TRUE), * 'markers' =&gt; array('multiple' =&gt; TRUE), * 'feed' =&gt; array('multiple' =&gt; TRUE) * This method however is not used in current code, so probably you don't need this operation. * * 'parse_macro'. -- use this hook, if your custom module needs to add extra keys into * GMap array. They will be added as [key] =&gt; [value] ---------------------- gmap_set_location($map, &amp;$form, $fields); * * Creates a map that can be interactively used to fill a form with a * location (latitude, longitude and zoom level) * * @param $map * Either a macro to use as the base map for setting a location, or an * already set map associative array. * * @param $form * A formset associative array. Cannot be more than one deep. * * @param $fields * An associative array for the field names. 'latitude', 'longitude'=&gt;name of * respective array, 'address' is optional. * * @return * A string with the google map code to be inserted onto the page. * ---------------------- gmap_geocode($address, $tld = 'com'); * * Utility function to use the google maps geocoder server side. * This is an easy, quick way to geocode a single address. * Note: This is a REMOTE CALL TO GOOGLE. Do NOT use this where performance matters, * as it could possibly take several seconds for this function to return. * See <a href="http://www.google.com/apis/maps/documentation/reference.html#GGeoStatusCode" title="http://www.google.com/apis/maps/documentation/reference.html#GGeoStatusCode">http://www.google.com/apis/maps/documentation/reference.html#GGeoStatusC...</a> * for a description of the possible status codes. * * @param $address * A string of address to be geocoded * * @param $tld * A string of domain naim ($tdl = 'com' yields into HTTP request of com domain: * 'http://maps.google.com' * * @return; * An array on geocoding results in the form of array('status', 'accuracy', 'latitude', 'longitude'). * On server error an array of 'status' =&gt; 500 is returned ---------------------- gmap_simple_map($latitude, $longitude, $markername = '', $info = '', $zoom = 'auto', $width = 'default', $height = 'default', $autoshow = FALSE, $map = array()); * * Simple way to draw a map from inside a theme. * * @param $latitude * Latitude of marker. * * @param $longitude * Longitude of marker. * * @param $markername * Marker to use. * '' will fall back to google's default marker. * * @param $info * What to show in the bubble when the marker is clicked. * Leave blank if you don't want a bubble. * * @param $zoom * Map zoom. * 'default' will use the default zoom from the settings page. * 3 is usually a good value to use. * * @param $width * Map width. * 'default' will use the default width from the settings page. * * @param $height * Map height. * 'default' will use the default height from the settings page. * * @param $autoshow * If set to TRUE, automatically show the marker bubble. * * @param $map * Override parts of the map array. * If you need to do much with this, you should probabaly be putting together * the map array manually. * * @return * A themed HTTP string with the google map code to be inserted onto the page. * ========================================== GMAP VIEWS API ---------------------- 1. Using views to provide additional overlay data to the produced map The gmap_views module also provides a small API for providing additional overlay data to the produced map. By defining: function hook_gmap_views_handle_field($phases, $data) You can tell gmap which column contains the geographic information it needs to plot the nodes on the map. There are two phases to the hook, 'discovery' and 'process'. During the discovery phase, your hook will be called once for each field in the view. If your module can transform this field into latitude and longitude coordinates, you should return a value. This value will be store and returned to you during the 'process' phase. This can be use- ful in caching information, such has how to process the data, etc. If your module cannot process this field, return NULL (the norm in most cases). In the 'process' phase, the $data arugment will contain two keys: - 'module' =&gt; this will hold the name of the field, the module that is being invoked (your module) and an 'extra' field, containing whatever you returned during the 'discovery' phase. - 'entry' =&gt; the views "entry" containing all the fields returned from the database/ From this data you should return an array with keys "lat" and "lon". Gmap_views will use this array to plot the node on the map. ---------------------- 2. Providing arguments to a GMap view Do not select an argument, instead expand the Advanced PHP Options textarea. Arguments can be provided in the form: $view-&gt;gmap_macro = '[gmap | center=30,10 | zoom=4]'; ben-agaric note: below example should use a more common module (i.e. not mine). For example, to retrieve information from a place-aware term on place panels: if (arg(0) == 'place' &amp;&amp; is_numeric(arg(1))) { $place_term = taxonomy_location_get(arg(1)); $view-&gt;gmap_macro = '[gmap |center=' . $place_term['latitude'] . ',' . $place_term['longitude'] . ']'; return $view; } <del> The gmap marker is converted to the javascript to display the map using the function gmap_draw_map($gmap, $javascript=''), where $gmap is a map variable and javascript is some javascript to be run when the map is loaded. Note that the string '{mapid}' in the javascript will be replaced with the mapid of the map being drawn. It should be noted that the default map settings provided on the admin/settings/gmap page will be used for any value that is not provided. An example of the gmap_draw_map function being used. $myshapes=array(array('color' =&gt; '#00dd00', 'type'=&gt;'line', 'opacity' =&gt; '0.5', 'points' =&gt; array( array('latitude'=&gt;'49.19011831503412','longitude'=&gt;'-123.20737838745117'), array('latitude'=&gt;'49.18506953036687','longitude'=&gt;'-123.16274642944336'))), array('color' =&gt; '#00dd00', 'opacity' =&gt; '0.5', 'type'=&gt;'line', 'points' =&gt; array(array('latitude'=&gt;'49.20526157803394','longitude'=&gt;'-123.19965362548828'), array('latitude'=&gt;'49.20077516864678','longitude'=&gt;'-123.16102981567383')))); $mymarkers=array(array('markername'=&gt;'blue', 'label' =&gt; 'Terminal bus stop', 'latitude' =&gt;'49.19236205396474', 'longitude'=&gt;'-123.1790542602539'), array('markername'=&gt;'green', 'label' =&gt; 'Service buildings bus stop', 'latitude' =&gt;'49.19224986943509', 'longitude'=&gt;'-123.1538200378418'), array('markername'=&gt;'green', 'label' =&gt; 'Transer to Vancouver bus', 'latitude' =&gt;'49.191801128772326', 'longitude'=&gt;'-123.14231872558594')); $mymap=array('id' =&gt; 'mymap', 'latitude' =&gt; '49.19258642226091', 'longitude'=&gt;' -123.17647933959961', 'zoom' =&gt; 13, 'width' =&gt; '100%', 'height' =&gt; '400px', 'type' =&gt; 'Satellite', 'shapes' =&gt; $shapes, 'markers' =&gt; $mymarkers); theme('gmap', array('#settings' =&gt; $mymap)); </del> </pre><p>BDragon must have misunderstood– I'm an <em>idea</em> person ;-) - it's the <a href="http://AgaricDesign.com/">Agaric way</a></p> <p>To get this started here's the consolidated issues relating to this documentation.

The maps would be configured dynamically depending on the particular user query, eg "show me all parks in France" or "show me all libraries within 50 miles of my home".</p> <p>I am trying to understand the best way to implement googlemaps on my site.<br /> Would it be better to code directly with the googlemaps api?<br /> Or better to use the gmaps+locations modules?</p> <p>At first newbie-glance, the googlemaps api looks relatively simple, and I imagine would offer the most flexibility. I am guessing, though, that the apparent simplicity of the googlemaps api is misleading, and that going with gmaps+locations would save me a lot of work.</p> <p>Any thoughts on the relative pros and cons of these two approaches?</p> <p>Thank you!!<br /> Mindy</p> <div class="og_rss_groups"><a href="/mapping">Location and Mapping</a></div> http://groups.drupal.org/node/6522#comments googlemaps gmaps Location and Mapping Wed, 10 Oct 2007 18:42:33 +0000 kobnim 6522 at http://groups.drupal.org http://groups.drupal.org/node/6452 <p>Is there a module that can plot site visitors on a map based on their IP address, sort of like Google Analytics?
