Harris SRTM-90 Gap Filled DEMs

The Harris ImageLinks 3 arc second (approximately 90m) void filled SRTM elevation data set is composed of 14277 one degree by one degree DTED “cells” covering approximately 80% of the earth’s landmass between 60 degrees North and 56 degrees South latitudes.

• Large SRTM voids were filled with 1km GTOPO while small srtm voids were interpolated.
• Filled voids common to multiple tiles were edge matched to ensure continuity.
• Horizontal and vertical accuracies match source SRTM except in void filled or interpolated regions.
• 3 arc second post spacing (approximately 90m).
• Longitude/Latitude lower left naming convention ie:e104n12.dt1.
• Total dataset size is approximately 36 GB (DTED format (not structure).
