When looking for a place to live, the surrounding area matters. Knowing if the property has easy walking access to shops, places of interest or public transport can definitely sway a buyer's purchasing decisions. Walk Score is a service that measures walkability within specific locations and also provides neighbourhood maps to the real estate industry. Walk Score's Travel Time API makes this functionality available to be easily integrated with other applications.
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.
