Political maps show you the lines that define political entities like countries, states and territories. These maps, generally, do not indicate any topographic features of the landmass. Even though people might think these lines are insignificant in our day to day life, that is not correct. Even things like where you are allowed to drive, how much tax you pay, and which side on the road you drive are based on these political boundaries. Most navigation software uses a combination of topographic and political maps. These maps show important political boundaries along with geographical features like rivers, roads and water bodies.
