ENVI SARscape Analytics: Persistent Scatterers

Megan Gallagher Tuesday, March 17, 2020

This blog is the third in a series that highlights one of the easy-to-use tools in the new ENVI SARscape Analytics (Persistent Scatterers). The first two blogs in this series featured videos about the Flood Mapping tool as well as the Time Series tool. ENVI SARscape Analytics was designed to make it quick and easy for those that may not be SAR experts to utilize SAR data for some of the most common applications.

This video focuses on the Persistent Scatterers tool. Persistent Scatterers uses time-series analysis to measure and monitor displacements of the Earth's surface over time. This tool is great at tracking changes at millimeter scale accuracies and finding areas where ground surface deformation has occurred. Many things can cause land deformation such as oil & gas and mining operations, or natural disasters like earthquakes, volcanoes, and landslides. Persistent Scatterers works best in urban environments, or rock face, which makes it a unique indicator of subterranean change in areas of high human population.
