Index of Mariner 9 Albedo mapping pictures of Mars Index of Mariner 9 Albedo mapping pictures of Mars

This photoindex shows locations of the Mariner 9 pictures that are the primary source materials for the albedo marking, overlays in the U.S. Geological Survey's "Atlas of Mars." All pictures were taken by the "A" camera. The individual pictures were selected to provide complete coverage of the planet at the smallest scales possible with a minimum of overlap. They thus provide the most...

Index of Mariner 9 mapping pictures of Mars Index of Mariner 9 mapping pictures of Mars

This photoindex shows nominal locations of the set of Mariner 9 pictures taken by the "A" camera that are the primary source materials for the 1:5,000,000 Mars maps. These pictures were selected because they have the highest resolution of any set with contiguous coverage of the planet. Most or the pictures were token according to sequences designed for mapping by the Mariner 9 imaging...

Land-use classification of the greater Denver area, Front Range Urban Corridor, Colorado Land-use classification of the greater Denver area, Front Range Urban Corridor, Colorado

The Greater Denver area, in the Front Range Urban Corridor of Colorado, is an area of rapid population growth and expanding land development. At present no overall land-use policy exists for this area, although man individuals and groups are concerned about environmental, economic, and social stresses caused by population pressures. A well-structured land-use policy for the entire Front...
