Geocoding is an integral part of using mapping APIs, as it converts from human-readable addresses to latitude and longitude points that the providers understand. It’s also not particularly easy to do on your own, so you’ll likely need a provider.
Below you’ll find an extensive, categorized list of geocoding providers.
- Yahoo (built-in, or use GeocodeAddress function)
- Mapstraction (a wrapper for multiple providers–see it in action)
Free Geocoder Web Services
Commercial Web Services
- Geocoder.US (four lookups for one cent)
Got any more?
I know I’ve missed some. What other geocoders need to be added to this list?
