Mest, Geologist 2014 1 map U.S. Geological Survey Scientific Investigations Map SIM 3245 Mars Transverse Mercator (MTM) –30247, –35247, and –40247 quadrangles cover a portion of southern Hesperia Planum and the highlands of eastern Promethei Terra, east of the Hellas basin. The map area (lat 27.5–42.5° S., long 110–115° E.) consists of cratered ancient highland materials of moderate relief, isolated knobs and massifs of rugged mountainous materials, extensive tracts of plains, and surficial deposits. Waikato and Reull Valles extend through plains and highland terrains. Regional slopes are generally to the southwest toward the Hellas basin, but local slopes (for example, highlands to plains dominate the landscape. To produce an up-to-date global geologic map for the Reull Vallis Region of Mars using modern bases including the Mars Global Surveyor (MGS) Mars Orbiter Laser Altimeter (MOLA) digital elevation model (DEM) (463 m/pixel resolution at lower latitudes to 115 m/pixel near the poles) (Smith and others, 2001) and the Mars Odyssey (ODY) Thermal Emission Imaging System (THEMIS) daytime infrared (IR) image mosaic (100 m/pixel) (Christensen and others, 2004).

URL: https://pubs.usgs.gov/sim/3245 none Unclassified none Esri ArcGIS 10.0 For the digital product presented herein, we used Mars Orbiter Laser Altimeter (MOLA) dataset to register the geologic map. The average accuracy of each point is originally ~100 meters in horizontal position and ~1 meter in radius (Neumann and others, 2003). However, the total elevation uncertainty is at least ±3 m due to the global error in the areoid (±1.8 meters) and regional uncertainties in its shape. The digital lines were drawn at approximately 1:2M scale. Geologic layers are horizontally tied to MOLA at a 1:20M scale. MOLA is horizontally accurate to the surface of Mars at 100 meters. Information has been obtained from sources believed to be reliable, but its accuracy and completeness and the opinions based thereon, are not guaranteed. As every effort is made to provide accurate information in this database, USGS would appreciate it if users could call to our attention any errors that may occur by communicating with the contact person. 20011025 1 document Journal of Geophysical Research: Planets Volume 106, Issue E10 http://onlinelibrary.wiley.com/doi/10.1029/2000JE001364/references onLine Mars Orbiter Laser Altimeter—Experiment summary after the first year of global mapping of Mars The MOLA-derived shaded relief image used for the base represents more than 600 million single altimeter measurements gathered between 1999 and 2001, adjusted for consistency and converted to planetary radii values. Using these values, elevations above the areoid were determined from the Martian gravity field solution GMM-2B (Lemoine and others, 2001). The average accuracy of each point is originally ~100 m in horizontal position and ~1 m in radius (Neumann and others, 2001). However, the total elevation uncertainty is at least ±3 m due to the global error in the areoid (±1.8 m) and regional uncertainties in its shape. The measurements were converted into a digital elevation model (DEM) using Generic Mapping Tools software, with a resolution of 128 pixels/degree (or 463 m/pixel at the equator). A shaded relief image was generated from the DEM with a sun angle of 45° from horizontal and a sun azimuth of 335°, as measured clockwise from north. The artificially illuminated MOLA DEM serves as the base for the printed geologic map. 20021206 1 document Space Science Reviews 110 http://www.mars.asu.edu/christensen/docs/christensen_themis_ssr.pdf onLine The Thermal Emission Imaging System (THEMIS) for the Mars 2001 Odyssey mission The THEMIS daytime and nighttime IR 230 m/pixel global mosaics (credit: Christensen, P.R., N.S.

We used the Environmental Systems Research Institute, Inc. (Redlands, CA) ArcGIS software package to co-register and analyze available datasets. Transverse Mercator versions of MOLA and THEMIS IR mapping bases were created in lossless PNG and GeoTiff format. Linework was drafted for the final scale at 1:1,000,000. 20110608 Planetary Science Institute Scott C. Mest mailing
