This week (much to the liking of many) Multimap released their OpenAPI. This now puts Multimap fare and sqaure in the community mapping scene and against the likes of Google and Yahoo who have established and well tested APIs. Multimap API has a few features that others don’t and it will be interesting to watch and discuss mashups as they get built.
As I write this post the Multimap forum has a discussion brewing about geocoding and decluttering. This looks to be the first mashup using the Miultimap API. Once the author has finished dev work I will surely put up a link.
