The Geocodio Reverse Geocoding Clojure Sample Code demonstrates how to convert latitude and longitude into street addresses. A response would show number, street, suffix, postdirectional, formatted street, city, county, state, zip, and country as address components.
Our API directory now includes 61 geolocation APIs. The newest is the Onuma WFS API. The most popular, in terms of mashups, is the Panoramio API. We list 45 Panoramio mashups. Below you'll find some more stats from the directory, including the entire list of geolocation APIs.
Map mashup developers take note. Google has just announced that it has made several changes to the Google Maps base map, which now includes several new base layers as well as well as more detailed information.
