Mapping InSAR Displacement

Illustration of a subsidence cone with an interferogram underneath it.

Detailed Description

Interpreting interferograms is a three-step process.  The first step is to map the InSAR displacement.  This is done by counting the number of InSAR fringes between two points on the interferogram, where one fringe is one complete color cycle (i.e. red, orange, yellow, green, blue, purple).
