A new service for city planners and others requiring detailed demographic and regional data has a great way of accepting geographic input. Cubit uses the Google Maps API to determine the area in which its user is interested. Then, it queries its own data sources based on the path or shape the user selects.
It's cleverly simple. The API provides a way to react to clicks on the map. Then, it draws lines along those clicks. When the user is drawing a polygon, Cubit automatically fills in the area. The Cubit Tour shows a video (embedded below) of the tool in action.
