Planimetric Maps







Planimetric maps are maps that show no relief features. They convey strictly 2D information; therefore, a feature, such as elevation, will never be found on a planimetric map. A common type of planimetric map is a street map. The picture above is an example of a planimetric map of Austin, TX. This map displays roads, landmarks, and bodies of water, but the main purpose of the map is to display major powerlines running throughout the city. It also includes the locations of dams found on the rivers. The map scale or ratio is 1:100,000.
