Example of data voids in SRTM data for an area in southeastern Utah
Detailed Description
Example of data voids in SRTM data for an area in southeastern Utah. Comparison of NED shaded relief (top image) and SRTM shaded relief (bottom image), with SRTM voids shown in light blue. Note how the voids occur at sharp changes in the topography. The area shown is about 32 km east-west by 19.7 km north-south.

Filtering of Elevation Difference Mask to Identify True Topographic Changes
The output of the differencing and thresholding procedures described above was a set of pixels with elevation differences large enough to be judged significant. Ideally, these differences would represent the set of true topographic changes that could then be used for further analysis. In reality, this was not the case, as the selected differences included areas that clearly did not reflect...
