Distance or area can be measured from any georeferenced raster dataset, mosaic dataset, or image service. A DEM is required if you're making measurements in 3D.
Measuring distance
The Distance tool measures the distance between two or more points.
- Click the layer in the Image Analysis window.
- Click the Distance tool.
- Click two or more points along the feature you're measuring.
- Double-click the last point to stop measuring.
Measuring area
The Area tool calculates the area and perimeter of a feature.
When 3D is checked, it will use the DEM to refine the calculation.
- Click the layer in the Image Analysis window.
- Click the Area tool.
- Click three or more points along the feature you're measuring.
- Double-click the last point to stop measuring.
