Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.3.1.1850 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: This product is directly derived from the USGS DLGs, which according to the National Mapping Program do not currently carry quantified accuracy statements. However, procedures used by the NMP to validate the attribute accuracy involve computerized checking of attribute codes against a table of valid codes to endure that each attribute in a file is valid for the category. A manual process involving proof plots is used to verify correct application of codes. The additional attribute added by Wyoming Gap Analysis, stream order, automatic generation by a ordering program. The coding was checked by displaying each order as a different color on screen, and special attention was paid to braided streams or other complicated areas of stream connection. The Strahler order attributes are correct only so far as the connectivity and completeness of the hydrographic network is represented due to generalizations at the 1:100,000-scale. Obviously, there will be differentiation in order at the larger 1:24,000-scale because of the more accurate representations of streams at that scale. Attributes were also checked by visual color displays for intermittent and perennial attributes, as well as natural vs. man-made (all ditches, canals and aqueducts were removed). One section of Wyoming should be noted in particular for incorrect attributing which was corrected by Wyoming Gap Analysis: streams in Weston county, particularly the Lance Creek 1:100,000 quadrangle, were incorrectly labeled as perennial when, according to USGS 1:24,000-scale topographic maps, they were actually intermittent streams. Some linear features were corrected where they were man-made ditches/canals but incorrectly labeled as natural streams (primarily in the Pinedale quadrangle). Approximately 12% of the 1,792 1:24,000-scale topographic maps for Wyoming were used to verify the 1:100,000-scale DLGS, however these quads were not statistically selected for verification but rather were selected to check areas that had already been identified as "problem areas". Logical_Consistency_Report: There are no unclosed polygons, intersections without nodes, or polygons without labels or with more than one label. Arc/Info's topological checking program CLEAN was used to correct intersections without nodes, identify unclosed polygons and remove duplicate lines with the same beginning and ending nodes. Checks were not made for possible errors such as sliver polygons or duplicate lines missed by CLEAN, though if any such errors exist they are likely to be minor due to the topological tests performed on the raw DLG data by the USGS NMP. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The USGS NMP identifies these procedures used to qualify the positional accuracy of their DLG products: the data are either manually digitized using equipment with a resolution of 0.001 inch and an absolute accuracy of from 0.003 to 0.005 inch, or are scanned on an automatic device with a resolution of 30 points per millimeter, or 0.0013 inch. The positional accuracy of the data and complete- ness of the file are checked by visually comparing proof plots with the original stable-base source material. These proof plots are generated using automated drafting machines with a resolution of 0.001 inch and an absolute accuracy of from 0.003 to 0.005 inch. Wyoming Gap Analysis converted raw DLG data into Arc/Info format with a 2 meter fuzzy tolerance (minimum distance between coordinates). Wyoming Gap Analysis also performed manual edge-matching along boundaries of 1:100,000-scale quadrangles of the source DLG data in Arc/Info, any positional offsets less than or equal to 200 meters being snapped together by splitting the distance between the two arcs. Other editing performed by Wyoming Gap Analysis which may or may not have an effect on the positional accuracy included adding or moving arc vertices and adding or lengthening arcs to join existing features in the edge-matching process. Grain tolerance used in adding/editing arc vertices was < 50m. Approximately 12% of the 1,792 1:24,000-scale topographic maps for Wyoming were used to verify the 1:100,000-scale DLGS, however these quads were not statistically selected for verification but rather were selected to check areas that had already been identified as "problem areas", areas where its was not possible to determine how to connect streams along quadrangle edges by referring to the 1:100,000-scale maps alone. Lineage: Source_Information: Source_Contribution: U.S. Geological Survey, National Mapping Program Process_Step: Process_Description: Raw DLG data (optional format) for Wyoming was converted to Arc/Info format 1:62,000-scale quads with a 2 meter coordinate resolution (fuzzy tolerance). These quadrangles were then tiled together into 1:100,000-scale quadrangles. During the process of tiling the 1:100,000-scale quadrangles into a statewide coverage, checking was done for proper feature alignment along the edges of the quads (edgematching). Streams or other hydrographic features with a positional offset (edge mismatch) of less than or equal to 200 m were snapped together by splitting the difference between them. In certain areas, it was necessary to refer to USGS 1:24,000-scale topographic maps to correctly determine the method of joining arcs. Editing changes included snapping endpoints of arcs together, adding or moving arc vertices, and adding new arcs to join or lengthen existing features. All arc features representing canals, ditches, or other man-made features were removed. Label errors which were identified by visual comparisons with paper maps were corrected. Process_Date: 199501 Source_Used_Citation_Abbreviation: DLG Process_Step: Process_Description: Following edgematching and other corrections to the original DLG data, all natural linear features were ordered, by major drainage (the state wide data was divided into 7 different drainages: North Platte, Belle Fourche, Crow, Wind River/Bighorn, Snake, Bear, Yellowstone) using the Strahler ordering method. The direction of flow of natural hydrographic features was adjusted using the Arc/Info TRACE command to best approximate the direction of flow in the drainage and its basins. A Strahler-ordering fortran program developed by USGS hydrologist, K. Lanfear, was applied to assign stream orders based on directional flow within the drainage. In cases of wide rivers represented by shorelines (instead of a stream centerline), braided rivers or stream networks interconnected circularly, the ordering had to rectified by interactive checking and editing. Wetlands, lakes, ponds and terminal reservoirs are not ordered. Streams flowing into Wyoming from other states (North Platte and Bear River drainages) were ordered based on visual inspection of source streams on 1:100,000-scale USGS maps of adjacent states (Colorado and Utah). Following the ordering and checking process, the individual drainages were appended back into a statewide coverage.
