Latitude longitude API's

Question

i have a address database and i tried to find latitude and longitude using google geocoding and yahoo API. Is there any other popular API's or programs are there.I'm using ubuntu platform.

Answer 1

I'm aware of at least one other geocoding system, OpenStreetMap. The only major differences I've found with any of these API's is the level of detail in each. OpenStreetMap has significantly less data, but is much easier to integrate with custom data. Also, I think the maps produced by google are the most beatiful of the three.

Answer 2

I was usually using Google Maps geocoding service over HTTP which returns you Json or XML as you like. Browse around here for more information about this.

Another option may be GeoNames.org. It also provides some interesting services and client libraries.

Answer 3

You might also find geocoder.us useful.
