Service Description: The DEM mosaics provided in this data set were generated from very-high-resolution (VHR) along- and crosstrack stereoscopic imagery from DigitalGlobe satellites. To generate DEM mosaic tiles, over 4000 DEM strips were merged with a weighted-average mosaicking routine that reduced errors and removed seams. Mosaic tiles are 100 km by 100 km with 12500 x 12500 pixels at 8 m. This data set reports elevation in meters above the WGS84 ellipsoid. The mosaics are derived from all available DEMs, regardless of date or sensor. The values represent a weighted average of all valid elevations at each pixel. Weights are assigned to penalize isolated pixels or “islands,” so that values from more spatially continuous DEMs have higher weights. The fill value for pixels containing no data is -9999.
