Alas of Mars chart, Mare Tyrrhenum Quadrangle, MC-22
United States Geological Survey
1973, Open-File Report 73-338
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
Interagency Report: Astrogeology 58, television cartography
Raymond M. Batson
1973, Open-File Report 73-21
The purpose of this paper is to illustrate the processing of digital television pictures into base maps. In this context, a base map is defined as a pictorial representation of planetary surface morphology accurately reproduced on standard map projections. Topographic contour lines, albedo or geologic overprints may be super imposed...
Atlas of Mars, Iapygia Quadrangle, MC-21
United States Geological Survey
1973, Open-File Report 73-337
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
Atlas of Mars chart, Aeolis Quadrangle, MC-23
United States Geological Survey
1973, Open-File Report 73-339
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
Atlas of Mars, Mare Acidalium quadrangle, MC-4
United States Geological Survey
1973, Open-File Report 73-328
This mosaic is made with computer enhanced Mariner 9 pictures, rectified and scaled to a Lambert conformal projection. Computer processing was performed by the Image Processing Laboratory (IPL) of the Jet Propulsion Laboratory (JPL). Processing included contrast enhancement and high-pass filtering which accentuates topographic features while subduing albedo variations. Photographic...
Atlas of Mars chart, Argyre Quadrangle, MC-26
United States Geological Survey
1973, Open-File Report 73-341
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
Atlas of Mars chart, Thaumasia Quadrangle, MC-25
United States Geological Survey
1973, Open-File Report 73-340
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
Regional gravity and magnetic surveys in the Albion Mountains area of southern Idaho
Don R. Mabey, Carol W. Wilson
1973, Open-File Report 73-165
Fault-bounded basins containing several thousand feet of sedimentary and volcanic rock of Cenozoic age are indicated by gravity lows in the Oakley area and in Upper-Raft River and Raft River Valleys. A gravity low and a magnetic high in the north end of Raft River Valley extends over the Cotterel...
