 Average Annual Precipitation (1961-1990) (1998)
This ftp site contains vector and polygon coverages of average monthly and annual precipitation for the climatological period 1961-90. Parameter-elevation Regressions on Independent Slopes Model (PRISM) derived raster data is the underlying data set from which the polygons and vectors were created. PRISM is an analytical model that uses point data and a digital elevation model (DEM) to generate gridded estimates of annual, monthly and event-based climatic parameters. Detailed descriptions of the PRISM raster data can be found with the accompanying raster data sets. For further information, the online PRISM homepage can be found at .

 Hydologic Unit Code Boundaries, 4th Level (1994)
The Geographic Information Retrieval and Analysis System (GIRAS) was developed in the mid 70s to put into digital form a number of data layers which were of interest to the USGS. One of these data layers was the Hydrologic Units. The map is based on the Hydrologic Unit Maps published by the U.S. Geological Survey Office of Water Data Coordination, together with the list descriptions and name of region, subregion, accounting units, and cataloging unit. The hydrologic units are encoded with an eight- digit number that indicates the hydrologic region (first two digits), hydrologic subregion (second two digits), accounting unit (third two digits), and cataloging unit (fourth two digits). The data produced by GIRAS was originally collected at a scale of 1:250,000. This data set is a modification for Wyoming of the original United States HUC data produced by the USGS. The primary modifications made in this data set by the Wyoming Water Resources Center include 1) removal of hydrologic units that do not drain witi Wyoming and 2) modification of the hydrologic unit boundaries to better encompass streams and lakes represented in the 1:100,000 scale Digital Line Graph (DLG) of surficial hydrography. The HUC boundaries have not been "clipped" to the Wyoming border, in order to maintain the natural boundaries of the units. This metadata has also been altered from original USGS metadata to be more specific for Wyoming.

 Hydrography 100k (1996)
Hydrographic features for Wyoming at 1:100,000-scale, including perennial and intermittent designations and Strahler stream order attributes for streams. Does not include man-made ditches, canals and aqueducts. The data was originally produced by USGS, a Digital Line Graph (DLG) product, though this product was enhanced (edgematched, some linework and attributes corrected, stream order attribute added). A subset of this dataset is also available for distribution, including only major streams (order 4 to 7) and major lakes and reservoirs. In order to reduce the size of this subset, the line segments were dissolved to remove unncessary segments. Both datasets are available in Arc export file and shapefile format for download (see Onlink_Linkage) Statewide and tiled data: there is one export file, which when imported into ARC/INFO, will contain one coverage with both polygon (lakes, reservoirs) and line (streams) topology and two feature attribute files (.PAT and .AAT) along with three additional attribute filecontaining descriptive information. In shapefile format, there will be two shapefiles (polygons and lines separated), with all attribute files in Dbase format.

 Irrigated Land (2000)
This data set is a polygon coverage. It only contains irrigated acreage in the Green River, Little Snake, and Great Divide basin within Wyoming. The initial interpretation of irrigated lands due to the works of man was taken from 1982 and 1983 aerial infra-red photos. The interpretation was then revised with 1999infra-red satellite photography. Upon completion of digitizing these areas, StateEngineer personnel provided comments for proposed alterations to the delineation. The data structure for this data set is based on graph theory, in which a two-dimensional diagram is expressed as a set of spatial objects in a manner that explicitly expresses logical relationships. Applied to a map, this concept is used to encode the spatial relationships between the objects, including such concepts as adjacency and connectivity between objects. A topologically structured data file can support graphic applications,as well as computations and analyses involving the spatial objects and their spatialrelationships. Irrigated lands and sub-irrigated lands are differentiated.

 Land Ownership and Management (1996)
This data contains land cover ownership and management information for the entire state of Wyoming at 1:100,000 scale. Attribute fields describe land ownership, manager/administrator (if any), Gap Analysis management code (which denotes the relative degree of biodiversity aintenance for each tract of land), and additonal land information such as U.S.F.S. National Forests and U.S.G.S. 1:100,000-scale quadrangles. Ownership designations reflect surface features only and do not include mineral or water rights. Though the ownership data was updated to 1994, updates should not be considered comprehensive and ownership may only be as current as the publication date of the source maps. The data is available for distribution as one statewide file or tiled into 56 separate files by USGS 1:100,000 quadrangle. The format for distribution is either ARC/INFO export format or ArcView shapefile.
