  7. Title: International Bathymetric Chart of the Arctic Ocean, 500-Meter Resolution GeoTIFF (Version 3.0)

    Contributors:

    Summary: This layer is a georeferenced image (GeoTIFF) of a digital bathymetric model (DBM) compiled with all multibeam, dense single beam and land data added at 500 x 500 meters resolution. The original (DBM) was compiled with all multibeam, dense single beam and land data added at 500 x 500 m resolution in a final step using the remove-restore method. Data were compiled from several multibeam cruises in the region dating from 1994 to 2011. The goal of this initiative is to develop a digital data base that contains all available bathymetric data north of 64° North, for use by mapmakers, researchers, institutions, and others whose work requires a detailed and accurate knowledge of the depth and the shape of the Arctic seabed.

  17. Title: Distribution Maps and Models for 13 Invasive Plants in Minnesota

    Contributors:

    Summary: This dataset consists of raster (.tif) and map (.png) files for 13 invasive plants in Minnesota. Species included consist of: common buckthorn, glossy buckthorn, multiflora rose, garlic mustard, Canada thistle, common tansy, leafy spurge, spotted knapweed, wild parsnip, purple loosestrife, Japanese knotweed, narrowleaf bittercress, and plumeless thistle. The rasters (.tif files) included here consist of the output of species distribution modeling (SDM) conducted for each species; these files depict the mean cross-model and cross-assumption distribution estimates for each species, on a scale of 0 to 1. Values near 0 indicate low likelihood of finding the species there, or low habitat suitability, and values near 1 represent a high likelihood of finding the species. The maps (.png files) included here depict the same information, but in a static non-GIS compatible format.

  18. Title: White-tailed deer density estimates across the eastern United States (2008)

    Contributors:

    Summary: In 2008, the Quality Deer Management Association (QDMA) developed a map of white-tailed deer density with information obtained from state wildlife agencies. The map contains information from 2001 to 2005, with noticeable changes since the development of the first deer density map made by QDMA in 2001. The University of Minnesota, Forest Ecosystem Health Lab and the US Department of Agriculture, Forest Service-Northern Research Station have digitized the deer density map to provide information on the status and trends of forest health across the eastern United States. The QDMA spatial map depicting deer density (deer per square mile) was digitized across the eastern United States. Estimates of deer density were: White = rare, absent, or urban area with unknown population, Green = less than 15 deer per square mile, Yellow = 15 to 30 deer per square mile, Orange = 30 to 40 deer per square mile, or Red = greater than 45 deer per square mile. These categories represent coarse deer density levels as identified in the QDMA report in 2009 and should not be used to represent current or future deer densities across the study region.

  19. Title: Global GIS : Geology of the conterminous United States at 1:2,500,000 scale : Geology

    Contributors:

    Summary: This datalayer is a polygon coverage representing geologic regions of the conterminous United States. It is a digital version of the geology features of H.M. Beikman and P.B. King's Geologic Map of the United States, originally published at a scale of 1:2,500,000 (1974). This version of the datalayer was published as part of the USGS Global GIS : global coverage database (2003). The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million. The U.S. Geological Survey (USGS) and The American Geological Institute (AGI) announced a cooperative agreement that will focus on making the USGS Global Geographic Information System (GIS) database readily available to educators and the general public in the form of a DVD based world atlas.
