Orthophoto map image. — An orthophoto map shows a portion of Rockville Town Center from 2017 (left) and 1998 (right).

Orthophotos are aerial images of the earth, looking down from a uniform height, and orthophoto images of Rockville date back to 1998, taken at intervals of every two or three years.

Find the new map among the featured maps at maps.rockvillemd.gov, or search “orthophoto” in the search field of the map gallery.
