Chapter Three: Google Maps View with Custom Overlays

Maps are a common feature many websites want to implement, and depending on requirements, often it is enough to simply embed the map. However, what if you want to create map markers using your own site data or use custom overlays to display additional geographic information? Drupal makes this quite easy with modules like Views and Gmap for Drupal 7.

A Drupal 8 port of GMap is in the works, and there is also the Geolocation D8 module which has Views and Google Maps support. For this article we will review a D7 implementation, although the Javascript code should be easy to adapt for D8 and Geolocation.
