Very detailed map/plan of town. It shows mostly every structure that is in town and is used by developers. If a new building or development is made, town plan must be updated to show correct structure again. You can also see town plans in 3D to get better understanding of how town really looks like. It is used for political purposes like urban environment design, transportation networks, strategic thinking, air and water infrastructure, but may also be used to navigate around town if you don’t have street and road map near you.
