Topographic Map of the Northeast Ascraeus Mons Region of Mars - MTM 500k 15/257E OMKT Topographic Map of the Northeast Ascraeus Mons Region of Mars - MTM 500k 15/257E OMKT
This map is part of a series of topographic maps of areas of special scientific interest on Mars. The topography was compiled photogrammetically using Viking Orbiter stereo image pairs. The contour interval is 250 meters. Horizontal and vertical control was established using the USGS Mars Digital Image Model 2.0 (MDIM 2.0) and data from the Mars Orbiter Laser Altimeter (MOLA).

Landsat yesterday and today: An American vision and an old challenge Landsat yesterday and today: An American vision and an old challenge
Since the late 1960s, the United States government has invested more than $1 billion in designing, launching, and operating the Landsat (land satellite) series of Earth-observing satellites. Global change researchers, geologists, and environmental scientists have used images gathered by the satellites for purposes ranging from human health research, energy exploration, and pollution...
Coastal-change and glaciological map of the Eights Coast area, Antarctica, 1972-2001 Coastal-change and glaciological map of the Eights Coast area, Antarctica, 1972-2001
Changes in the area and volume of polar ice sheets are intricately linked to changes in global climate, and the resulting changes in sea level may severely impact the densely populated coastal regions on Earth. Melting of the West Antarctic part alone of the Antarctic ice sheet could cause a sea-level rise of approximately 6 meters (m). The potential sea-level rise after melting of the...
