Creating Maps with Visualforce

Maps communicate information more clearly than mere location data. Visualforce mapping components make it simple to create maps that use third-party mapping services. Visualforce maps are interactive, JavaScript-based maps complete with zooming, scrolling, and markers based on your Salesforce or other data. Create stand-alone map pages, maps that you can insert into page layouts, and even mobile maps for Salesforce1.

Create Visualforce maps with a set of related mapping components. <apex:map> defines a map canvas, including map size, type, center point, and initial zoom level. <apex:mapMarker> child components define markers to place on the map, by address or geolocation (latitude and longitude).

Maps that you define generate JavaScript code to render onto the page. This JavaScript connects to a mapping service and builds the map by fetching map tiles, placing markers, and even geocoding addresses if you don’t have a latitude and longitude. After the map renders, your users can interact with the map by panning and zooming, just like they’re used to with other popular map sites. The effect is if you wrote your own custom JavaScript to interact with a third-party mapping service, but without needing to actually write that JavaScript. You define the map in Visualforce and get the mapping JavaScript for free.

Visualforce mapping components aren’t currently available in Developer Edition organizations.
