These data are based on LP-DAAC, where each 3-as data point is the average of the nine 1-as samples surrounding the post and differ from the DTED1 subsampled data available from USGS SDDS seamless server or distribution DVD's. Automated process used to generate 8.3333333333333333333333333333333e-4 pixel size headers and ingest into Arc-Grid format using the exact geometric center of the lower left pixel for registration; correcting 1/2 pixel shift found in other distributions. Coastal masking based on 1-as SWDB data to set Oceans from zero to no-data and fill terrestrial voids also conducted. Update based on CIAT interpolated data also prepared, pending corroboration of shift. 1x1 tile to maximize AOI specific post-processing.
