Measure distance or area from an image

Distance or area can be measured from any georeferenced raster dataset, mosaic dataset, or image service. A digital elevation model (DEM) is required if you're making measurements in 3D.

Tip:

The units for these measurements can be changed in the Mensuration Results .
