Values for the VV polarization are commonly driven by surface roughness and/or soil moisture, with rougher surfaces and higher soil moisture returning higher backscatter values. Surface water appears very dark under calm conditions, as the signal bounces off the surface away from the sensor.", "summary": "Radiometric Terrain Corrected (RTC) product in VV polarization generated in dB scale at 30 meter pixel spacing from Sentinel-1 SAR imagery, processed by ASF.", "title": "RTC dB Scale", "tags": [], "type": "Image Service", "typeKeywords": [ "Data", "Service", "Image Service", "ArcGIS Server" ], "thumbnail": "", "url": "", "minScale": 0, "maxScale": 0, "spatialReference": "", "accessInformation": "RTC products processed by ASF DAAC HyP3 2023 using GAMMA software.
