What is Drupal?

Why Drupal for Web Mapping?

Core Drupal Concepts

Mapping modules for Drupal

Requirements: GeoPHP / GEOS

Store data: Geofield, PostGIS Get data: Address Field (+ Autocomplete), Geocoder, GDAL Serve data: Views GeoJSON Map data: Leaflet, OpenLayers

3 recommended approaches: Leaflet -or- OpenLayers -or- Views GeoJSON + custom code

Leaflet

Lightweight, but less customizationRecommended modules: Leaflet, Leaflet More Maps, Leaflet Views

Example: warmshowers.org

OpenLayers

Lots of control via GUI, but corresponding overheadSee also: cartaro.org (bundling OpenLayers, PostGIS, etc. in a docker container)

Example: contratados.org

Views GeoJSON + custom code

"Headless Drupal" approach -- expose data via geojson and then map it yourself

Example: Durham's Civil Rights History

Demo

Spinning up a live site using drush (www.drush.org)Prerequisites: MAMP/LAMP/WAMP stack, drush installed

$ drush dl drupal
Project drupal (7.39) downloaded to /Users/tim/htdocs/mapping_demo/drupal-7.39.                                                     [success]
...

$ mv drupal-7.39/ docroot
$ cd docroot/

$ drush si --db-url=mysql://user:passwd@localhost/db_name
