    Hello everyone, I am performing PS Interferometry analysis on a stack of Cosmo-Skymmed Images. When reaching the Geocoding step, the PS Map (.shp and .kml files) is properly generated providing the information I'm interested in. However, I have checked the Make Geocoded Raster flag in order to obtain the displacement velocity map as a raster, and It has not been created ( note I have also unchecked the Create Geocoded Shape). And, by the way, is it possible to make the PS map less dense? It has consumed a lot of computing time. Only by increasing the coherence threshold the number of points can be reduced? Thanks, Santiago

    I have responded to this question in our SARscape forum. Although there I did not address the density of PS points. SARscape will return all of the persistent scatterers it finds that meet the criteria you set. The only way to have it return less persistent scatterers is to adjust the coherence threshold so that only the points with the highest coherence are found. - Peg Exelis VIS
