Process_Step:
Process_Description:
The first step in producing the image was the creation of a digital elevation model (DEM) of Venezuela using data from the Shuttle Radar Topography Mission (SRTM). These same data are currently available from the EROS Data Center. The original DEM's have a resolution of 3 arc-seconds in the horizontal (approximately 90x90 m). Visible flaws in the spliced data set were repaired using techniques such as data interpolation. Patched data was reprojected to an Equidistant Conic projection, having a grid-cell size of ~90m. The final step in generating the based DEM was to delimit the elevation data at sea level by adding a coastline digitized from 1:500,000-scale geologic maps of Venezuela. Data processing preformed by Christopher Garrity, USGS Eastern Energy Resource Team.
