A lot of Google Maps use cases require to plot regions, such as sales sectors, maintenance zones or potential
customer markets.
Doing this manually is often tedious and error-prone. Since a lot of use cases are based on
administrative boundaries (states, cities and others), our best option
is to use the administrative boundary as a starting point.
For example we have a customer whose sales representatives are deployed on specific zones. Each zone is typically based on a French "département" (an administrative region). It can be a full département, or half a département, or a third...
For a bit of fun I wrote a quick demo of this approach. The demo application allows you to split a département in two zones. Each zone will be affected to a sales representative.
You can then use Google Maps' geocoding feature to test any address you want and see if it lands on one of the zones you just created.
