Frequency distributions of lunar slopes, part C

The metric and panoramic cameras aboard the Apollo 16 spacecraft provided photographs on which photogrammetric techniques may be used to obtain precise measurements of horizontal distances and elevations. It is reported that these measurements may in turn be used to obtain slope-frequency distributions of lunar surfaces at various slope lengths and for various types of terrain and geologic map units. Bistatic radar and photoclinometric methods were also used to obtain the same data.
