The Radar System (RDRS) Topographic Maps, Planetary Radius, Harmonic Coefficient (TOPO) data products include a 360th degree and order spherical harmonic topography model, and a digital map of the topography. The topography model of Venus was produced by a spherical harmonic analysis of the most complete set of Magellan altimetry data, augmented by Pioneer Venus and Venera data. A detailed report on this harmonic analysis and its scientific implications is in Rappaport and Plaut, 1994 (doi:10.1006/icar.1994.1167).
TOPO data files. Unless otherwise noted, files have a detached PDS label (.XML in PDS4 and .LBL in PDS3).
