The Yahoo PlaceFinder API gives developers multi-language global geocoding of named places.
PlaceFinder supports building-level address recognition in over 75 countries, and points of interest, airports, cities, and other place names (including administrative areas) for these countries and the rest of the world.
In addition to supporting free-form, single-line, and multi-line address inputs, PlaceFinder also supports queries that include cross streets, WOEID, and IATA airport codes. It also supports reverse geocoding: you can give it a longitude/latitude coordinate and get back the nearest address.
Almost every app that uses a mapping API needs latitude/longitude points. To get geocodes you need to convert an address to a point on the earth. That's where you'll need one of the 54 geocoding APIs in our directory. This post covers seven free geocoders and compares them on several aspects.
Yahoo has added to its suite of useful geographic tools with a brand new geocoder called PlaceFinder. This replaces Yahoo's old geocoding API and joins another 7 Yahoo mapping APIs in our directory for a total of 43 Yahoo APIs.
