  6. Title: Color North America Shaded Relief: 1-Kilometer Resolution

    Contributors:

    Summary: The North America Shaded Relief data were derived from the GTOPO30 elevation data. GTOPO30 is a global digital elevation model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer). GTOPO30 was derived from several raster and vector sources of topographic information. It was developed between 1993 and 1996 through a collaborative effort led by staff at the U.S. Geological Survey's EROS Data Center (EDC). The following organizations participated by contributing funding or source data: the National Aeronautics and Space Administration (NASA), the United Nations Environment Programme/Global Resource Information Database (UNEP/GRID), the U.S. Agency for International Development (USAID), the Instituto Nacional de Estadistica Geografica e Informatica (INEGI) of Mexico, the Geographical Survey Institute (GSI) of Japan, Manaaki Whenua Landcare Research of New Zealand, and the Scientific Committee on Antarctic Research (SCAR). This file is a replacement for the January 2003 map layer. This map layer was previously distributed as North America Shaded Relief. This layer is part of the 1997-2014 edition National Atlas of the United States. The Shaded Relief image was developed to portray the terrain of North America. It is intended for visual purposes only. The original GTOPO30 data must be used for conducting analysis and determining elevation values. National Atlas of the United States. (2003).

  11. Title: Alaska Geologic Formations, 1997

    Contributors:

    Summary: Alaska Geologic Formations is a polygon theme representing geologic formations throughout Alaska. This dataset consists of a polygon coverage and associated attribute data derived from the 1980 Geologic Map of Alaska compiled by H.M. Beikman and published by the US Geological Survey. The map is a regional summary of geologic formations and units that can be shown cartographically at 1:2,500,000. This digital dataset includes all (184) map units from the original map. 182 are geologic units; the others are polygons for large glaciers and lakes. This coverage is not intended to be a complete representation of the printed geologic map. It does NOT include the following features: faults, locations of volcanoes or volcanic vents, the map explanation, correlation charts or description of map units.

  13. Title: NASA Surface Meteorology and Solar Energy

    Contributors:

    Summary: A renewable energy resource web site of global meteorology and surface solar energy climatology from NASA satellite data on one by one degree resolution. NASA's Prediction of Worldwide Energy Resource (POWER) Project is developing data sets from Earth Science Enterprise climate research to support renewable energy industries. The Surface meteorology and Solar Energy (SSE) data set contains solar parameters principally derived from satellite observations and meteorology parameters from an atmospheric model constrained to satellite and sounding observations. It is a 22-year climatology (July 1983- June 2005) on a one-degree latitude by one-degree longitude grid. The global coverage of the SSE data set fills the gap where remote locations lack ground measurement data. Most ground measurement stations are located near populated regions that may have natural or urban influence on the local climate. The SSE data set can augment ground measurement data affected by microclimates. There are parameters for sizing and pointing solar panels, solar thermal applications, cloud information, temperature, humidity, and wind parameters. The SSE data are considered accurate for preliminary feasibility studies of renewable energy projects. Shapefile data downloaded from OpenEI (http://en.openei.org) on June 16, 2014. System requirements: Geographic Information Systems (GIS) software that reads ESRI shapefile format.

  15. Title: World Wildlife Fund Terrestrial Ecoregions, 2005

    Contributors:

    Summary: World Wildlife Fund Terrestrial Ecoregions represents global terrestrial ecoregions. Ecoregions are defined as relatively large areas of land or water in the world containing a characteristic set of natural communities that share a large majority of their species, dynamics, and environmental conditions. This data set contains all terrestrial ecoregions, which include those of the Global 200. Global 200 ecoregions are a collection of the Earth's most outstanding and diverse terrestrial, freshwater, and marine habitats where the Earth's biological wealth is most distinctive and rich, where its loss will be most severely felt, and we must protect if we are to preserve the web of life.

  17. Title: North America: River Network, 30s resolution, 2009

    Contributors:

    Summary: This river network (stream lines) map for North America is derived from the flow direction map for North America. The flow accumulation map for North America is used for selection and attribution. Only rivers with upstream drainage areas exceeding a certain threshold are selected: for the 15 arc-second resolution a threshold of 100 upstream cells has been used. The vectorized river reaches are attributed with the maximum flow accumulation (in number of cells) occurring within each river reach. This data is derived from elevation data of the Shuttle Radar Topography Mission (SRTM) at 30 arc-second resolution approx. 1km at the equator. The goal of developing HydroSHEDS was to generate key data layers to support regional and global watershed analyses, hydrological modeling, and freshwater conservation planning at a quality, resolution and extent that had previously been unachievable. HydroSHEDS has been developed by the Conservation Science Program of World Wildlife Fund (WWF), in partnership with the U.S. Geological Survey (USGS), the International Centre for Tropical Agriculture (CIAT), The Nature Conservancy (TNC), and the Center for Environmental Systems Research (CESR) of the University of Kassel, Germany.
