ENVI SARscape Analytics: Flood Mapping

Megan Gallagher Thursday, October 17, 2019

This blog is the first in a series that highlights one of the easy-to-use tools in the new ENVI SARscape Analytics. The second blog in this series features a video about the Time Series tool and the third covers Persistent Scatterers. 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.

The really cool thing about using SAR data for this application is that SAR can see through clouds and even rain, so you can get much more timely information instead of having to wait for a storm to clear for optical imagery analysis.
