The SRTM is a raster product assembled by the U.S. Geological Survey, designed to provide elevation with a consistent datum, elevation unit, and projection The cell values represent a composite illumination value from 0 - 255 and elevation classification. Color shaded relief surfaces are mainly used as background in mapping and displaying data. A color elevation image was created by slicing the elevation data using the ranges (meters) and RGB color values below.

Before producing all, but the shaded relief data sets the 30m DEM want through a 4 step conditioning process. These steps include: the Delta Surface Fill Method, stream burning, 3x3 spatial smoothing, and hydrologic sink filling process. The original SRTM DEM has gaps or voided data values throughout its coverage area. These gaps were a result of a number of issues such as topological shadowing, phase unwrapping anomalies, or other radar-specific causes (USGS, 2006). These gaps were filled with existing lower resolution DEM data sets using a SRTM/DEM merge process called Delta Surface Fill (DSF) developed by the United States National Geo-spatial-Intelligence Agency (NGA) (Grohman 2006). The lower resolution DEM used to fill the gaps were a combination two data sets. These data sets include a 90m DEM derived from contour lines based off NGA's Vector Smart Map (Vmap) level 1 product where available and CGIAR-CSI SRTM 90m filled SRTM data was used (CGIAR, 2004). For details on CGIAR method for filling data gaps visit http://srtm.csi.cgiar.org/SRTMdataProcessingMethodology.asp. The stream burning was only applied to areas of the DEM were preliminary drainage networks were not consistent with the natural drainage network represented in orthorectified Landsat ETM imagery or were physical barriers needed to broken such as dams or elevation anomalies that would of caused excessive filling during the fill process. The 3x3 spatial smoothing was applied to minimize any anomalies that occur in SRTM DEM data sets while preserving the linear drainage network (Lehner, 2006). The final step in conditioning the DEM was to fill all anomalous sinks using ArcGIS Hydrology Fill process. Natural sinks were identify and preserved.
