DTED (Digital Terrain Elevation Data) Study

reportActive / Technical Report | Accession Number: ADA269399 | Open PDF

Abstract:

Terrain height errors have significant effects on studies sensitive to atmospheric quantity and structure, such as USAFETACs atmospheric profiles point analyses. A recent study concluded that the primary source of degradation in atmospheric profile quality was caused by the coarse grid spacing of the eighth-mesh terrain data used in the Air Force Global Weather Central AFGWC Atmospheric Slant Path Analysis Model ASPAM. This report documents a study that determines the feasibility of incorporating the Defense Mapping Agency DMA high density Digital Terrain Elevation Data DTED into the AFGWC atmospheric profile model. The report also describes a procedure developed by USAFETAC to make the dataset smaller and save computer storage space.
