Howto: Creating user friendly mapping for non-drupal nerds
This howto will help you create a simple method for your clients to add locative information to a travelogue. I've been fiddling with a lot of options for doing this, including using feeds with gmap macros. Though gmap macro feeds have the advantage of offering specific marker types for the different feeds, I ended up using a method which does away with that feature, but gains tremendously in useability, due to the fact that the writer doesn't need to know the exact feed syntax and gmap macro syntax to make it work.
Read moreUse cases
I wonder if we could come up with a bunch of use cases.
I've been working on mapping for a client, and it's a very hot area at the moment. There are loads of projects in the wild and a whole host of back end tools. Coming up with a decent list of what we expect to be able to do with Drupal seems like a good place to start. Of course lots of these use cases will already be covered in the existing modules.
Put your ideas in the comments. If this is a successful strand of conversation, then we'll probably need to work out which of the use cases are most important.

Locationfield module: does this exist?
Wondering if this has been built yet, or if I should start from scratch.
I'm looking for a CCK text field that takes a "nice" value for location such as "Montreal, QC" and converts it in the back-end to "45.518376,-73.56308" so that it can be displayed in a Google Map, or searched via proximity or etc. I've attached a mock-up so you know what I mean. 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).

Community Almanac - RFP to build an online mapping platform
The Orton Family Foundation, which we frequently work with, just put out an RFP to build an online mapping platform that helps them do community asset mapping in cities and towns they work in. Read more >>. We feel like it's a great match for Drupal and are planning to put a proposal together, but would love to partner up with someone who's involved, or wants to get involved in the gmap rewrite, to make sure we can use this opportunity to help move this effort forward.

User Map
Hi,
I'm using the gmap module for generating a map of user locations, but I'm getting a weird error on the map. It says :
warning: array_intersect() [function.array-intersect]: Argument #1 is not an array in /var/www/html/cms.projectpier.org/sites/all/modules/gmap/gmap_location.module on line 96.
Can any offer some help? I noticed in the locations table there were some errors with lat/long = 0.0, so I deleted them hoping it might clear up the problem but no luck.

Type based distinction for events, location information
Currently, our event listing is a flowing river of information and it is quite hard to distinguish between different types of events. 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:
- User group meeting
- Regional conference
- International conference
- Virtual meeting (IRC meetings, Drupal dojo)
- Training
GMap API.txt 5.x rewrite
Hello! Bdragon here.
Benjamin Melançon suggested using a wiki page to rewrite gmap's API.txt for Drupal 5. I think it's a great idea.
Therefore, I'm asking for assistance with the rewrite. Please help rewrite and expand the document to describe how things actually work in 5, and I'll commit them to CVS.

Event content type, Locations, and GMap
I am trying to create a map of node locations, but only for nodes of type Event and Event with Volunteer Timeslots. I've got Location and GMap configured with the API key in all the right places. I'm using the latest dev releases of these modules.
However, when I create a new event node with location data, no geocoding occurs. If I query the location table, I can see my node with the correct location, but the latitude and longitude fields are null.
I looked at location.module in the location_nodeapi() function. Around line 842, I see:

?>googlemaps api versus gmaps
Hi all, newbie question.
I would like to add maps to my drupal site. 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".
I am trying to understand the best way to implement googlemaps on my site.
Would it be better to code directly with the googlemaps api?
Or better to use the gmaps+locations modules?
Module showing visitors plotted on a world map?
Is there a module that can plot site visitors on a map based on their IP address, sort of like Google Analytics? It seems like there should be, but my searches have been fruitless. Anyone heard of such a thing?
