There are arrows pointing from the globe to one of the layers on the right. The right side has a set of six squares one on top of the other with space in between. The top has dots and is labeled customers. Second one is a street map and is labeled streets. Third is an outline of land areas. It's labeled parcels. Fourth layer is a grid with squares different colours. It looks like a river is running diagonally across it. Fifth layer is similar to the fourth, but has different colours. It's labeled land usage. The bottom layer shows different land heights, There's a river running though the middle with a city on one side and trees and rocks on the other. "/>
