Topographic map of the Coronae Montes region of Mars - MTM 500k -35/087E OMKTT
This map is part of a series of topographic maps of areas of special scientific interest on Mars. The topography was compiled photogrammetrically using Viking Orbiter stereo image pairs. The contour interval is 250 m. 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).
Results of land cover change detection analysis in and around Cordillera Azul National Park, Peru
The first product of the Optimizing Design and Management of Protected Areas for Conservation Project is a land cover change detection analysis based on Landsat thematic mapper (TM) and enhanced thematic mapper plus (ETM+) imagery collected at intervals between 1989 and 2002. The goal of this analysis was to quantify and analyze patterns of forest clearing, land conversion, and other disturbances
Geologic map and coal stratigraphy of the Blue Gap quadrangle, eastern Washakie Basin, Carbon County, Wyoming
This report provides a geologic map of the Blue Gap 7.5-minute quadrangle, located along the eastern flank of the Washakie Basin, Wyo. Geologic formations and individual coal beds were mapped at a scale of 1:24,000; surface stratigraphic sections were measured and described; and well logs were examined to determine coal correlations and thicknesses in the subsurface.

Geohydrology of the Valley-Fill Aquifers between the Village of Greene, Chenango County and Chenango Valley State Park, Broome County, New York
This set of maps and geohydrologic sections depict the geology and hydrology of valley-fill aquifers in the 14-mile reach of the Chenango River valley between the Village of Greene and the area south of Chenango Valley State Park, N.Y. This map report depicts the aquifers; locations of domestic, production, and test wells; surficial geology; water-table altitude; potentiometric-surface altitude; g
Geologic map of northwestern Seattle (part of the Seattle North 7.5' x 15' quadrangle), King County, Washington
This map is the first of four new geologic maps covering the city of Seattle that are based on field exposures and an extensive database of subsurface geologic explorations. The landforms and near-surface deposits here record a relatively brief, recent period in the geologic history of the region that was dominated by the last advance of the continental ice sheet that covered the region about 17,0
