Compares Rockville, Then and Now
Ever wanted to see a side-by-side map comparison of how Rockville looked during two different periods? Now you can, with a new online “orthophoto” map tool, one of the city’s numerous geographic information system maps.
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. Both images side by side can be compared by moving the slider bar back and forth, or by panning the map. For complete instructions, open the “About” tool on the map toolbar.
Find the new map among the featured maps at maps.rockvillemd.gov, or search “orthophoto” in the search field of the map gallery.
