Yahoo! has been a surprising leader in online geo APIs, with
Placeinder
for converting addresses
or place names into coordinates,
GeoPlanet
for getting category and neighborhood information
about places, and
Placemaker
for analyzing text documents and extracting words or phrases that
represent locations. You'll need to
sign up for an app ID
,
but after that it's a simple REST/JSON
interface.
You can also
download a complete list
of the locations that Yahoo has in its database, holding
their names and the WOEID identiier for each. This can be a useful resource for doing oline
processing, though it is a bit hobbled by the lack of any coordinates for the locations:
curl "http://where.yahooapis.com/geocode?\
q=1600+Pennsylvania+Avenue,+Washington,+DC&appid=<App ID>&flags=J"
