Geocoding involves converting a description of a physical address into coordinates that represent that location on a map to perform spatial analysis. This tutorial on the Google Maps APIs blog describes the two approaches to geocoding with Google Maps APIs, and when to use them.
Eleven APIs have been added to the ProgrammableWeb directory in categories including Blockchain, Location, and File-Sharing. Featured is an API from the US Department of Veterans Affairs for Veteran health data, and an API that tracks user location using artificial intelligence.
Google continues to expand its third version of the maps API to include features already in the second version. Most recently, they've added driving directions, which gives programmatic access to the routing data between two points. As with the rest of Maps V3, which was released in May, the team took a fresh approach, so some interfaces have changed.
