The Lunar Reconnaissance Orbiter Camera (LROC) consists of one Wide Angle Camera (WAC) for synoptic multispectral imaging and two Narrow Angle Cameras (NAC) that provide high-resolution images (0.5…
The Cassini mission has returned an abundance of data about the surface of Titan. To maximize the science return from these data and to assist with planning for Cassini and future missions, we have…
RAND/USGS Planetary Geodesy (RUPG) Software ISIS QMATCH Program Measurement Input and Output File
Stuart has suggested that I draft some suggestions for the format and names to be used for parameters in the randlsq.F program. I previously implemented the limited naming of parameters in this…
The overall problem we’re solving is that we want to be able to set up the relationships between the coordinates of arbitrary physical points in space (e.g. ground points) and their coordinates on…
Cassini observations show that Saturn’s moon Titan is slightly oblate. A fourth-order spherical harmonic expansion yields north polar, south polar, and mean equatorial radii of 2574.32 T 0.05…
Cassini RADAR SARtopo and altimetry data are used to construct a global gridded 1 x 1° elevation map, for use in Global Circulation Models, hydrological models and correlative studies. The data are…
The USGS Astrogeology Science Center Honoring 50 Years of Public Service: Exploring the Solar System from Flagstaff, AZ
Since arrival at Mars in Sept. 1997 the Mars Orbiter Laser Altimeter (MOLA) on the Mars Global Surveyor (MGS) spacecraft has obtained a number of topographic profiles across the northern hemisphere…
The Pathfinder mission made use of a unique capability to rapidly generate and interactively display three-dimensional photo-realistic virtual reality (VR) models of the Martian surface. The Stereo…
