This product has been superseded by Magellan Global Topography 4641m v02 (1997). Global Topographic Data Record (GTDR). The range to surface is derived by fitting altimeter echoes from the fan-beam…

The images used for the base of this globe show the northern and southern hemispheres of Venus as revealed by more than a decade of radar investigations culminating in the 1990-1994 Magellan mission.…

Product Information: Global Reflectivity Data Record (GREDR). The power reflection coefficients are derived by fitting altimeter echoes from the fan-beam altimetry antenna as a function of time to…

Product Information: This Global Emissivity Data Record (GEDR) includes all Magellan measurements in which the high-gain antenna followed the nominal look-angle profile, in which the observed…

We present a GIS package for the 1:2,500,000 geological map of the Alpha Regio (V-32) quadrangle, Venus. The V-32 quadrangle extends from 0° to 25 S, 0°to 30° E with an area of approximately…

Product Information: In this Global Slope Data Record (GSDR) the surface meter-scale slopes are derived by fitting altimeter echoes from the fan-beam altimetry antenna as a function of time to…
