Data Set Abstract |
This data set contains the Magellan Global Topographic Data
Record (GTDR). The range to surface is derived by fitting
altimeter echoes from the fan-beam altimetry antenna as a
function of time to Hagfors' radar backscatter model
templates. The ranges are subtracted from the spacecraft radial
coordinate (derived from Doppler tracking), yielding measurements
of planetary radius. The data are filtered to remove
low-frequency errors in the in-plane elements of each spacecraft
orbit, and then re-sampled into sinusoidal, Mercator, and north
and south polar stereographic projections at a resolution of
about 5x5 kilometers per pixel. |
