So in keeping with this week’s mapping theme, if you look at APIs sorted by type on ProgrammableWeb you can see there are now 44 APIs in the mapping category. That’s a lot of mapping-related APIs and constitutes nearly 10% of all the APIs listed at ProgrammableWeb. They may not all be what you expect. Here’s a breakdown for you:
- The big players: The ones you expect. Google Maps API, Yahoo! Maps API, Microsoft Virtual Earth API, AOL MapQuest API (and not to forget GIS encumbent ESRI ArcWeb).
- Specialized startups: Use the GeoIQ API for rich data visualization that builds on top of Google Maps. The HopStop API lets you integrate mass-transit and walking directions into your own website. For neo-geographic, social community mapping there’s the Platial API or the WayFaring API. If you want maps that understand neighborhoods you could use the Urban Mapping API. Share your location and discover others nearby with the Plazes API. Get 3D mapping capabilities with the Poly9 FreeEarth API. Or, a bit more unusual is the Where’s Tim API that let’s you track the location of Tim Hibbard 24×7.
- Geocoding services: to turn addresses into latitude and longitude: geocoder.us, geocoder.ca, Ontok and Yahoo! Geocoding (note that Google and others now offer geocoding within their own mapping APIs).
- Government sponsored: This includes APIs like the USGS Elevation Query Service from the Geological Survey returns the elevation in feet or meters for a specific latitude-longitude point. NASA provides mapping images via their satellite image API.
- Regionally focused: The European mapping leader is the Multimap, down under in Australia and New Zealand there’s the Whereis API and ZoomIn API, and in Korea you’ll want to use the Naver Maps API. There’s also the Nearby.co.uk geocoding API and also for the UK is the iShareMaps On Demand API that geocodes UK addresses to a postcode level.
There are many thousands of maps mashups out there and we’re now up to a catalog of 1100+ map mashups listed here.
Geo-anything is clearly a hot segment of the online web services space.
