Hello rcrajapp , Keep in mind that the DISP-S1 data is in the line of sight of the SAR sensor, which is a side-looking instrument. As such, there are both horizontal and vertical components to displacement values. You may need to take this into consideration when correlating the data to hydrologic p...

The NISAR mission will be generating only the nearest-neighbor GUNW products (12-day interferograms). These products will be processed automatically as new data is acquired, and archived for public use. Custom pairings for other date ranges would currently need to be generated by users themselves. I...

If you're interested in comparing the NISAR GCOV products to similar Sentinel-1 data, the OPERA RTC-S1 products provide terrain-corrected radar backscatter in gamma-nought power for Sentinel-1 acquisitions.

Have you evaluated the GCOV products , or are you looking specifically for non-terrain-corrected data? While the GCOV products present normalized radar backscatter in gamma-nought power, they also include a layer for conversion to sigma-nought. They also contain the calibration layers used, includin...

iwa103 , The NISAR mission makes some higher-level products available directly in the archive without the need for additional processing. This includes Geocoded SLCs (GSLC), 12-day Geocoded Unwrapped Interferograms (GUNW), and Geocoded Covariance (GCOV) products, which can be used in place of an RT...

This may have to do with the recent update of the EGIS platform from ArcGIS Enterprise 11.4 to 11.5. Here's some guidance from the EGIS team: EGIS URLs Issues: If you’re seeing errors when accessing gis.earthdata.nasa.gov/portal/home or other EGIS URLs, it is most likely due to cached web files from...

Hi gdervin , To generate a DEM from SAR, it's best to have two images that are acquired very close together in time, but from slightly different places in space. You could try generating DEMs from ALOS PALSAR L1.1 products, but there are a number of issues that may be problematic: - ALOS had a repea...
