DEMs Created from Airborne IFSAR – An Update

  title={DEMs Created from Airborne IFSAR – An Update},
  author={Bryan Mercer},
The factors affecting the wide-scale use of DEMs (Digital Elevation Models) and their associated ORRIs (Ortho-Rectified Radar Images) created from airborne IFSAR (Interferometric Synthetic Aperture Radar) have been evolving rapidly over the past few years. These factors include both technical and non-technical characteristics. In this paper we review several of these characteristics including vertical accuracy, sample spacing, image resolution, bald-earth extraction, vegetation penetration… CONTINUE READING
