This enhancement would allow for computing the interferometric coherence contained within custom geospatial features (e.g., polygons, lines with a buffer, points with a buffer). The output of this can be the input to change detection algorithms available in external software packages. The following processing steps are proposed:1. Import vector data (with support for shapefile).2. Backgeocode to get radar coordinates. Note that a DEM is required for this step.3. Select azimuth/range pixels contained within the vector data.4. Compute interferometric coherence for selected pixels.5. Export as vector data (shapefile), now including a new attribute corresponding to the interferometric coherence.
