Description

These datasets include point locations and quality descriptions for the geolocation analysis section of the Synthetic Aperture Radar (SAR) radiometric terrain correction (RTC) comparison project led by NASA-USAID SERVIR. 'True' points were collected using DigitalGlobe high resolution MAXAR imagery. The geolocation measurement error for each location was compared across 7 analysis ready SAR products at 10 global locations and measured using ArcMap Desktop.

SAR Analysis Ready Data software/methods compared:

  • RTC: GAMMA, SNAP, ISCE-2
  • GTC in Google Earth Engine
  • GRD in Google Earth Engine
