Forest cover types (deciduous forest (41), evergreen forest (42), mixed forest (43), shrub/scrub (52), woody wetland (90)) were isolated from the 2001 National Land Cover Dataset (1 = forest, 0 = non-forest). To improve processing time of running a large focal mean across an expansive region, the “aggregate” tool was applied to the forest grid and re-sampled the 30 m pixels to 90 m using the mean aggregate option (i.e., the result is new 90 m pixels representing the proportion of forest in 9 pixels). A 10 km circular focal mean was applied to the aggregated grid resulting in a new floating point raster containing the proportion of forest within 10 km of each 90 m pixel. These values were multiplied by 100, rounded...
Mineral Information Layer for Oregon-Release 2 (MILO-Release 2) is a geospatial database that stores and manages information regarding Oregon's mineral occurrences, prospects, and mines. Understand that recreation in or around inactive mine sites is extremely dangerous, and can result in serious injury or death. Stay out and stay alive!
This digital map shows the areal extent of surficial deposits and rock stratigraphic units (formations) as compiled by Trimble and Machette from 1973 to 1977 and published in 1979 under the Front Range Urban Corridor Geology Program. Trimble and Machette compiled their geologic map from published geologic maps and unpublished geologic mapping having varied map unit schemes. A convenient feature of the compiled map is its uniform classification of geologic units that mostly matches those of companion maps to the north (USGS I-855-G) and to the south (USGS I-857-F). Published as a color paper map, the Trimble and Machette map was intended for land-use planning in the Front Range Urban Corridor. This map recently (1997-1999)...
Mineral Information Layer for Oregon-Release 3 (MILO-Release 3) is a geospatial database that stores and manages information regarding Oregon's mineral occurrences, prospects, and mines.
This digital map shows the geographic extent of rock stratigraphic units (formations) as compiled by Colton in 1976 under the Front Range Urban Corridor Geology Program. Colton used his own geologic mapping and previously published geologic maps to compile one map having a single classification of geologic units. The resulting published color paper map (USGS Map I-855-G, Colton, 1978) was intended for land-use planning and to depict the regional geology. In 1997-1999, another USGS project designed to address urban growth issues was undertaken. This project, the USGS Front Range Infrastructure Resources Project, undertook to digitize Colton's map at 1:100,000 scale, making it useable in Geographical Information Systems...
This dataset consists of records for over 1,500 mineral facilities in Africa and the Middle East. The mineral facilities include mines, plants, mills , or refineries of aluminum, cement, coal, copper, diamond, gold, iron and steel, nickel, platinum-group metals, salt, and silver, among others. Records include attributes such as commodity, country, site, company name, plant capacity if applicable, and generalized coordinates. The data were compiled from multiple sources, including the 2004 USGS Minerals Yearbook (Africa and Middle East volume), minerals statistics and information from the USGS minerals information Web site (http://minerals.usgs.gov/minerals/), and data collected by USGS minerals information country...
