Spatial Analysis

Example of wide-area mapping of terrain deformations over mainland Greece. This GPS-calibrated deformation map covers 65 000 sq km – approximately half of the country’s territory. This map was created using 10 individual ERS-1/2 stacks, each stack being a time series of 58 to 76 SAR images acquired from 1992 to 2003 for a total of 671 images. Source: ESA.

Using Remote Sensing to Measure Land Deformation

The European Space Agency has developed a new land data processor to create maps of land deformation.  Called Wide Area Processor (WAP), the processes uses radar data to measure millimeter terrain deformations.  Changes in the surface height of a landscape occur over time.  Sinking of the earth can happen as a result of mining, […]
