Mapping solutions in Drupal range from powerful configuration options in OpenLayers to simple one-line address fields that display a Google Map. Leaflet is a lightweight, mobile-friendly Javascript mapping library that uses Geofield to store location data. Geofield plus Leaflet is a solution with more options and flexibility than the Simple Google Maps contributed module, for example, and far less complexity, and fewer configuration options, than OpenLayers. If you're looking for an easy way to dive into mapping without pulling your hair out, then this webinar is for you.
Join Amber Matz, as she walks through the process of adding a map to your Drupal site using Geofield and Leaflet. In this webinar, you'll learn:
