Historical Analysis Overview

3vG can conduct a data archive search of all of the relevant satellite image databases to determine data availability over your specific area of interest. If sufficient imagery is available, we can conduct an InSAR analysis of these images to measure displacement over the associated time frame. An example of the type of InSAR results generated from historical archive images for a portion of a major U.S. city is shown in the figure to the right.

We are very impressed with this data. We realized that we have problems right now in several areas caused by rain. We saw them shown in red on the map.”
