Description:This product assembled for FEMA by New Light Technologies (NLT) and ImageCat http://www.imagecatinc.com/ represents a point on each building in the Sandy inundation zone (319,575 total buildings), as well as points where visible aerial imagery damage determinations were made outside the inundation zone. Where available, the visible aerial imagery damage determination (15,256) overrules the inundation based damage assessment, “Destroyed” determinations were only based on imagery determinations, and imagery based damage determinations helped calibrate the depths we used to estimate inundation damage levels.
