Browse Interferometric (InSAR) Data Format

Browse InSAR images are intended to give users an idea of the quality of data collected for repeat pass interferometry and a rough indication of whether an interferogram contains useful signal. Each product contains a meta data file (ann) describing the files and kml/kmz representations of the following ground projected multilooked products:

  • interferogram phase (int)
  • correlation (interferometric coherence) (cor)
  • amplitude of acquisition 1 (amp1)
  • amplitude of acquisition 2 (amp2)
  • ampcor range offsets (osr)
  • ampcor azimuth offsets (osa)
  • DEM used to ground projection (hgt)

UAVSAR browse RPI products are always processed with no residual motion correction with azimuth resolution of 3 meters.
