We derived near‐global lunar topography from stereo image data acquired by the Wide‐angle Camera (WAC) of Lunar Reconnaissance Orbiter (LROC) system. From polar orbit tracks, LROC WAC provides with a mean ground resolution at nadir 75 m/pixel substantial cross‐track overlap. images one‐year nominal mission and first months science phase are combined to produce digital terrain model (DTM) pixel spacing 100 m, Global DTM or “GLD100.” It covers 79°S 79°N latitudes, 98.2% entire surface. compare...

Automated procedures for ground processing of Mars Express HRSC data have been developed and are applied systematically immediately after download in order to provide calibrated sets as well photogrammetric image 3D products within a short time frame.

The High Resolution Stereo Camera (HRSC) on the European spacecraft Mars Express is first camera a planetary mission especially designed for photogrammetric and cartographic purposes. Since January 2004 has been taking image data from Martian surface, characterized by high-resolution, stereo capability color. These provide an enormous potential generation of 3D surface models, color orthoimages, topographic thematic maps, additional products. acquired undergo calibration systematic...
Abstract We carried out an extensive cartographic analysis of the Apollo 17 landing site and determined mapped positions astronauts, their equipment, lunar landmarks with accuracies better than ±1 m in most cases. To determine coordinates a body‐fixed coordinate frame, we applied least squares (2‐D) network adjustments to angular measurements made astronaut imagery (Hasselblad frames). The measured networks were accurately tied provided by 0.5 m/pixel, controlled Lunar Reconnaissance Orbiter...
Newly acquired high resolution Lunar Reconnaissance Orbiter Camera (LROC) images allow accurate determination of the coordinates Apollo hardware, sampling stations, and photographic viewpoints. In particular, positions from where 17 astronauts recorded panoramic image series, at so‐called “traverse stations”, were precisely determined for traverse path reconstruction. We analyzed observations made in surface photography as well orthorectified orbital (0.5 m/pixel) Digital Terrain Models...
Aims. New astrometric measurements for Phobos are reported on the basis of 69 SRC (Super Resolution Channel) images obtained during 28 Mars Express flybys executed between 2004 and 2007.
Between July 2005 and 2011 Mars Express performed 50 Deimos approaches. 136 super resolution channel (SRC) images were acquired used for astrometric (positional) measurements of the small Martian satellite. For this study, we have developed a new technique, in which center-of-figure odd-shaped is determined by fitting predicted to observed satellite limb. The prediction limb was made based on moon's known shape model. camera pointing verified corrected means background star observations. We...
Abstract. Planetary Cartography does not only provides the basis to support planning (e.g., landing-site selection, orbital observations, traverse planning) and facilitate mission conduct during lifetime of a observation tracking hazard avoidance). It also means create science products after successful termination planetary by distilling data into maps. After mission’s lifetime, higher level like mosaics digital terrain models (DTMs) are stored in archives – eventually maps higher-level form...
