MapQ is an easy to use wrapper for the Mapquest Geocoding API. It advises developers to interact with the API by making the environment variable in the local environment. Developers can also interact with the Geo class to work with the API.
Yesterday, Yahoo announced its new Internet Location Platform API, "a resource for managing all geo-permanent named places on Earth" that "provide[s] the Yahoo! Geographic Developer Community with the vocabulary and grammar to describe the world's geography in an unequivocal, permanent, and language-neutral manner."
MapQuest's recent entree into mobile developer tools is an interesting one. Choosing Android over iPhone means going toe to toe with Google, a familiar competitor to MapQuest on the mapping front. Mapping is logically MapQuest's turf. The company was helping people find directions online before Larry and Sergey were even in graduate school, let alone leaving to found Google. Of course, another way of looking at it is that Android is in line with MapQuest's latest push to open up mapping data.
Anyone who lives in even a smaller city knows the importance of neighborhoods. Portland (where I live), for example, is really more like a collection of many connected small towns. Each has its own handful of coffee shops and restaurants. The people behind GeoReach API (our GeoReach API profile) understand this. The API provides neighborhood boundaries, along with local content.
