The National Hydro Network (NHN), for which the standard was officially adopted by the Canadian Council on Geomatics (CCOG) in August 2004, focuses on providing a quality geometric description and a set of basic attributes describing Canada's inland surface waters. It provides geospatial vector data describing hydrographic features such as lakes, reservoirs, rivers, streams, canals, islands, obstacles (e.g. waterfalls, rapids, rocks in water) and constructions (e.g. dams, wharves, dikes), as well as a linear drainage network and the toponymic information (geographical names) associated to hydrography.The NHN forms the hydrographic layer of the GeoBase. The best available federal and provincial/territorial data are...

This raster file represents classification and mapping results for priority area 1 of the Cody Region and Yellowstone National Park land cover remote sensing project. Extensive field collected reference data describing the range of plant communities and habitat types comprising the Bighorn Basin have been analyzed to produce a classification of land cover types based on the Wyoming Game and Fish Department (WGFD) Wildlife Observation System (WOS). Corresponding land cover classes were subsequently spatially modeled using a non-parametric Classification and Regression Tree (CART) algorithm that integrated both spectral data from Landsat Thematic Mapper satellite imagery and a variety of ancillary environmental data...

This dataset contains polygons describing photo interpreted map classifications of the Tongass National Forest developed in 1978. The dataset's primary objective was to delineate major land types and their attributes. The land types were mapped at a polygon level - areas generally homogenous in character. Mapping was done to a 10 acre minimum except for non-commercial and non-forest types which were mapped to a 5 acre minimum. The classification identifies water as well as land. It segregates land into non-forest and forest. Polygons in forested areas were assigned a single, representative set of attributes; species composition, age, and volume class. Tim86 was updated in the 1980's (mostly in 1986) to reflect timber...

This web mapping service displays the Vegetation Class attribute of the Pacific Northwest GNN Forest Structure Model. Many other attributes are available in the data set. For more information about these other attributes, and to download the data, please visit the LEMMA site here:http://lemma.forestry.oregonstate.edu/data/structure-mapsGNN models for individual species are also available at http://lemma.forestry.oregonstate.edu/data/species-maps. The GNN models apply only to forest land (areas currently or with the potential to support at least 10% tree cover), because a consistent regional plot sample of non-forest areas is unavailable. Most users will want to use "masked" versions of the GNN maps, which are...

Raster file of land use and land cover mapping in the 'Lander' study area at 30m pixel level. Map extent corresponds to 6,490,062 acre area of central Wyoming in the counties Fremont, Natrona, Carbon, Sweetwater, and Hot Springs. A 3km buffer was applied to map extent extending the raster file into the counties of Washakie, Park, Teton, and Sublette.

Raster file of land use and land cover mapping in the 'Rawlins' study area at 30m pixel level. Extent corresponds to the area of the USDI Bureau of Land Management Rawlins Field Office within Sweetwater County, Wyoming plus an average buffer of 5km.

Annual raster-based maps of LULC conditions for the years 1938 to1992 were created based on information on historical patterns and prescriptions of LULC change. The intent of these historical LULC projections was not to recreate exact past LULC conditions, but to provide useful maps of simulated historical land-cover for use in secondary analysis. The baseline LULC condition was derived from a modified version of the 1992 National Land Cover Dataset (http://www.epa.gov/mrlc/nlcd.html). Historic data and others were used to guide a spatially explicit (FOREcasting SCEnarios of land-cover change) land-cover forecasting model in allocating LULC change distributions on the landscape, based on logistic regression analysis...

This file geodatabase includes the 2013 Land Use/Land Cover (LULC) and the Marxan target rasters that were derived from it. For an explanation of why targets were selected and how they were derived, please refer to the report. The Python scripts used to generate the layers are also available via the GNLCC portal.
