The Topographic and Bathymetric Shaded Relief of North America map layer shows depth and elevation ranges using colors, with relief enhanced by shading. The image was derived from two pre-existing map layers; the Bathymetric Shaded Relief of North America, derived from ETOPO2 data, and the Color North America Shaded Relief, derived from GTOPO30 data.
This dataset was developed by the Crown Managers Partnership, as part of a transboundary collaborative management initiative for the Crown of the Continent Ecosystem, based on commonly identified management priorities that are relevant at the landscape scale. The CMP is collaborative group of land managers, scientists, and stakeholder in the CCE. For more information on the CMP and its collaborators, programs, and projects please visit: http://crownmanagers.org/This geodatabase contains all freely available spatial information on trails accessible by All-Terrain-Vehicles (ATV’s) as well as utility and logging cutlines in the Crown of the Continent area. Due to the free nature of the data, it is of mixed quality...
The Satellite View of the Conterminous United States map layer is a 200- meter-resolution simulated-natural-color image of the United States. Vegetation is generally green, with forests in darker green and grasslands or shrublands in lighter green. Areas of high reflectance, including urban areas, rock, and dry bare soil, are shown in shades of pink. Very bright areas, such as snow and ice, are colored blue. The image was produced by combining Landsat Thematic Mapper (TM) imagery from the Landsat 4 and Landsat 5 satellites. The National Atlas map layer released in December 2005 as Satellite View of the Conterminous United States is now called Satellite View of the Conterminous United States, with Shaded Relief.
Current as of April 4, 2013:This geodatabase contains all freely available spatial information on surface wellsites related to energy resources in the Crown of the Continent area. Due to the free nature of the data, it is of mixed quality and should not be considered inclusive of all wellsites actually in the region. Some wells may possess a “Cancelled” status and lack a drilled hole but may still represent a clearing made for the once planned activity.Alberta Source: current as of September 2009; Montana Source: 1998-2000 (Ground water wells: 2009); and British Columbia Source: 2007-2008.
This layer represents the stream network for the Crown of the Continent Ecosystem. The data are a compilation from multiple sources.
This map layer is an image of nighttime lights for North America, including the Caribbean and most of Mexico. The data were collected in 1996 and 1997 as part of the Defense Meteorological Satellite Program (DMSP). The data available through the National Atlas of the United States are in GeoTIFF format. This is a revised version of the May 2002 map layer, with a corrected shoreline for Greenland.
These data represent forest cover use for the Crown of the Continent Ecosystem. The data are a compilation from multiple sources. These data were derived from the CCE land cover map.
