Dynamic marker icons for Leaflet


I have a situation where I need to display content with different terms on a Leaflet map. These terms also are associated with images. At this point, I would like to ask you whether the below can be done.

1) Multiple layers: To show different images, I might need to have multiple layers. Is this possible?
2) Dynamic icons: Is this possible, either with token or something else?

Undefined index: title


I am trying to build a map thatuses postal address rather than lat/long. I am getting the notice Notice: Undefined index: title in openlayers_views_style_data->map_features() (line 330 of DRUPAL_ROOT/sites/all/modules/openlayers/modules/openlayers_views/views/openlayers_views_style_data.inc).

How to fix it?

EDIT: I accidentally created this as a user story, sorry about that.

Reusing a field across multiple content types, opinions please

I have multiple content types - restaurants, hotels, events for example, and each of them has a location field.

I want to show all restaurants on one map, all hotels on anther etc, and also all content types on one map. I've achieved this using separate location fields on each content type - field_hotel_location, field_event_location, etc - Openlayers and Views.

I was at last able to create and display a map with leaflet. I now have a question though. How can I create multiple layers with different markers? EDIT: So far, I've tried adding another block display to the view and filtering it with a term.

Support geospatial raster data in Cartaro

Right now Cartaro only supports geospatial vector data stored inside a PostGIS database. This project will add support for geospatial raster data by implementing a user interface to add, update and delete raster data. GeoServer will be used to publish any raster data as WMS layers.

Addresses in Turkey


I'm trying to display some addresses in Turkey on a map. For this purpose, I've created a few nodes with legit addresses and followed http://calibrate.be/labs/using-openlayers-and-geofield-display-maps-drup.... However, I couldn't get it to display any Turkey addresses (US addresses no problem though). Can anyone suggest a good read for doing that?

One content type, two map fields

I'm not sure whether this is an Openlayers or Geofield question.

I have a content type with two map based fields
trail - geofield - Openlayers map
start_points - geofield - Openlayers map

They both use separate input maps, both maps are set to 'Geofield - Fuels the geofield map-input form'.

I want to display all information on one map, which I've done, using a view.

use exif information from images to show locations in google maps

I want to use the exif that is uploaded with my images, to show the location of where the picture was taken.

Is there a simple tutorial for that.

with the module exif it is possible to extract the geo-information of my image and store it somewhere ......but....how to do that

then i have to create a view in which both picture and google map are show ...but..how to do that.
As you can see I am very new to this. Your help is very much appreciated.

Multiple content types, each with a map

I have 3 custom content types, each with a map.

I've created separate input maps - OpenLayers maps, each with the Geofield - Fuels the geofield map-input form checked - and associated them to the field on each of the content types - Manage Fields - Location Field - Field Type: Geofield - Widget: OpenLayers Map. These seem to be capturing the data.

To display the fields on a node page I've created views where the format is OpenLayers Data Overlay,

Best practice for geolocation: addressfield + geofield + geocoder vs text + geofield + geocoder

I am asking for input on the the best practice for having a user enter a location and then having the system geocode that location.

Addressfield + geofield + geocoder
Addressfield allows one to enter in each part the location if they know it
It allows a developer to access each piece of the address easily
Integrates with alot of other Drupal modules

You cannot have a piece of the address by required and the others not.
For example, I hardly ever know what the zip code of a venue or location is yet if addressfield is required, I have to enter it.
