MGN V RDRS 5 GLOBAL DATA RECORD SLOPE V1.0
Listed in NASA Data Portal
This data set contains the Magellan Global Slope Data Record (GSDR).
Description
The surface meter-scale slopes are derived by fitting altimeter echoes from the fan-beam altimetry antenna as a function of time to Hagfors' radar backscatter model templates. The data are then re-sampled into sinusoidal, Mercator, and north and south polar stereographic projections at a resolution of about 5x5 kilometers per pixel.
Each GSDR image pixel is represented by a 8-bit unsigned integer.
