Mapping in Drupal 7 using OpenLayers
25 likes16,781 views
This document discusses using the OpenLayers mapping framework with Drupal. It introduces OpenLayers and describes how it can be used to add mapping capabilities to Drupal. The key steps are to add geospatial data using the Geofield module, create maps using the OpenLayers module, and display maps through Views. Additional modules like Geoserver can integrate external map services with Drupal. The document provides examples and discusses ways to customize maps through OpenLayers modules, code, and contributed projects.
Mapping in Drupal 7 using OpenLayers

- 4. OpenLayers is ... ‣ a framework for building map applications ‣ javascript ‣ open source (BSD licensed) ‣ your escape from Google Maps
- 7. maps.ed.gov
- 8. Under Development 7 drupal
- 9. 6 drupal 7 drupal ‣ OpenLayers CCK ‣ Geofield ‣ OpenLayers Geocoder ‣ Geocoder ‣ OpenLayers Filter ‣ ? ‣ Geo Taxonomy ‣ ? ‣ OpenLayers Plus ‣ ? ‣ OpenLayers Proximity ‣ ? Note that this list is incomplete
- 10. Modules ‣ ctools ‣ openlayers openlayers_ui, openlayers_views ‣ geofield geoPHP ‣ views
- 11. Example
- 12. Geo Data ‣ CCK Field: ‣ Data with ‣ Can be geofield latitude/ anything that is supports points, longitude available in lines & polygons (e.g. integers) Views! field storage input field type
- 13. Adding geo data with lat/lng fields with OpenLayers Map Widget Data is stored in geofield
- 14. And our rendered node
- 15. Mapping in 3 steps 1. Layer Services: Google Maps, MapBox, ... Files: KML, XML, ... Drupal nodes via Views 2. Map Configuration for a single map 3. View Displays the map using Views
- 16. 1. Layer 2. Map 3. View use Views to select data from CCK
- 17. 1. Layer 2. Map 3. View configure data source to pick up the location
- 18. 1. Layer 2. Map 3. View pass additional data to the layer
- 19. 1. Layer 2. Map 3. View use OpenLayers module to configure map
- 23. 1. Layer 2. Map 3. View use Views to display map
- 24. 1. Layer 2. Map 3. View select map to display
- 26. Step by step Add geofield (Field) 1. Create data overlay (Views) 2. Create map (OpenLayers) 3. Render map style (Views)
- 27. Improvements
- 28. Map Behaviors ‣ Pop Up ‣ Zoom to layer ‣ Cluster ‣ Write your own (javascript)
- 30. Change Layers ‣ Google Maps ‣ MapBox ‣ Create your own (e.g. via TileMill)
- 32. Geoserver 1. Drupal outputs WFS via Views 2. Geoserver reads WFS and creates map 3. Openlayers reads Geoserver map, displays and facilitates interaction ! 6 drupal http://drupal.org/project/wfs http://geoserver.org

- 36. geocoder 7 drupal ‣ From address to location ‣ Use geocoder services (e.g. Google Geocoder) ‣ Can take values from Address Field or any other text !
