deformation NASA ASF Level 1 active
In plain English

What it measures. An elevation map of the terrain, showing surface height for an imaged scene.

How it's made. Produced from the airborne UAVSAR radar flown on a Gulfstream-III aircraft, delivered as a simple image file. (The provided description is very brief.)

How & where you'd use it. Used as a terrain-height reference, for example to support analysis of the radar imagery it accompanies.
