Color-coded map of SRTM data overlaying the topo map for
"Benjamins Butte" (Pk 500+ meters).
The max data points for the SRTM data are seven 495m (1624-ft) points. That is, there are no data point at or above 500m. Each data point is a point at a specific latitude-longitude with a reported average elevation for a 30m radius disk centered at that point.
The topo map contours have been labeled with large black text. The small contour labels are for the SRTM data. You will probably have to view the original size image to see this detail.
