The TownMe API, at GeoAPI.com, has now been fully incorporated into Twitter's services. Before the acquisition, it included both read and write geo-related services. The read side had a reverse geocoder which helped translate coordinates (AKA lat/longs) into human readable elements or associations. For instance, give the API "37.78093,-122.409415" and it returned information about the census tract, neighborhood, city, MSA, and state that contains these coordinates.
The POI Finder took a lat long and gave a set of points of interests including businesses close to that point. This meant anyone could build services that allowed users to broadcast location or otherwise interact with their "real location".
The write components of the API included:
MSHT3 is a pure Google Maps version 3 mashup utilizing new Google Geocoding and Elevation services, combined with Yahoo! Query Language accessing Yahoo! Geoplanet. US Zip Code and County polygons are...
There is a new wave of mapping APIs that are helping developers provide better location feedback to users. These "reverse geocoders" do more than just return an address. Instead, they provide meaningful names associated with the place, such as a business. In some cases, it gets even more specific.
If you are as optimistic as we were about Twitter's location features, you should be downright giddy now. Twitter has acquired the company--and staff--behind one of the most innovative mapping-related APIs. Mixer Labs' GeoAPI , previously known as TownMe, hosts your geographic data and allows spatial queries such as "find the closest location" (for more see our earlier TownMe news coverage and our TownMe API profile).
It's been less than a month since Mixer Labs released the first version of its read/write location API, formerly know as the TownMe GeoAPI. Now Mixer Labs has rebranded the TownMe GeoAPI as GeoAPI.com and released several new features as part of the rebranding.
