California accuracy study test areas

California accuracy study test areas:

PhotoSat has tested the elevation surveying accuracy of a number of stereo satellite data sets using highly accurate LiDAR data in SE California.  This data is available from opentopograpy.org.

Image of the Opentopography.org bare ground LiDAR elevations over the Honda Test Track PhotoSat stereo satellite accuracy test area. This is very high quality LiDAR data. On areas of bare ground with slopes of less than 20% grade this data is probably accurate to better than 5cm in elevation.
