MapBuilder.net is an Web2.0 service or rapid mashup development tool to build custom Google and Yahoo maps without any knowledge of the Google/Yahoo Maps API and JavaScript. MapBuilder provides a decent visual interface for the map building process with geocoding and import features. Also MapBuilder lets users tag locations on their maps, and then publish the map either on MapBuilder.net or their own website.
As a short summary I would like to say that Map Builder is:
- a great tool for webmasters, webdevelopers, people who likes mapping at all.
- an excellent resource to get started with Google or Yahoo maps.
- a good resource to build communities around your maps or just start collaborated map development.
