GTDR	Global Topography Data Record - Global Topography and Surface Property Set (GXDR) This is an ODE Logical Product. NOTE: These products were initially distributed on tape and then CDs. The documentation terminology still reflects this form of distribution. More Information: Introduction to GXDR Archive GXDR README.TXT GXDR Product Software Interface Specification (SIS)	urn:nasa:pds:magellan_gxdr
GVDR	Global Vector Data Record (GVDR) - The GVDR is a sorted collection of scattering and emission measurements. The sorting is into a grid of equal area 'pixels' distributed regularly about the planet. For data acquired from the same pixel but in different observing geometries, there is a second level of sorting to accommodate the different geometrical conditions. The 'pixel' dimension is 18.225 km. The GVDR is presented in Sinusoidal Equal Area (equatorial), Mercator (equatorial), and Polar Stereographic (polar) projections. This is an ODE Logical Product. NOTE: These products were initially distributed on tape and then CDs. The documentation terminology still reflects this form of distribution.

Stereo-Derived Topo Data	Using a fully automated process, the left-left stereo data collected by Magellan were used to generate topography for ~20% of the planet. The map was generated by Robert R. Herrick at the University of Alaska, Fairbanks. Please see the document for more information.	urn-nasa-pds-magellan_stereo_topography

Type	Description	PDS3 Data Set
FBIDR	Full-Resolution Basic Image Data Record - The F-BIDRs are full-resolution images in the form of long, narrow, almost pole-to-pole swaths.
