Description:
Abstract:
This geodatabase contains basin boundaries and sites used to delineate basin boundaries. In particular, the basin boundares in this geodatabase are used by the Colorado Water Science Center to generate numeric drainage areas published in the annual Water Data Report and on NWISWeb. This dataset was published with a U.S. Geological Survey Techniques and Methods report entitled "Digital Database Architecture and Delineation Methodology for Deriving Drainage Basins, and Comparison of Digitally and Non-Digitally Derived Numeric Drainage Areas."
Purpose:
This geodatabase was developed in 2009 to be a digital archive for basin boundaries developed by the U.S. Geological Survey (USGS) Colorado Water Science Center. The geodatabase contains a topology and three feature classes inside a feature dataset "container." The geodatabase and its contents were generated for the purpose of determining accurate drainage-basin areas for publication in NWISWeb and in the Annual Water Data Report.
This geodatabase includes a single feature dataset, BasinsFD, which, itself, contains three feature classes: BasinLines, BasinPolys, and Sites. The feature dataset also contains topology rules stored as a topology called BasinsFD_Topology.
The original, prototype geodatabase included linework from various sources and was changed in 2009 to rely on the National Watershed Boundary dataset (WBD) of the U.S. Department of Agriculture, Natural Resources Conservation Service. The WBD was used because it is a nationally consistent dataset that is seamless across the conterminous United States. Other linework needed to generate a basin boundary for a specific site was manually digitized from USGS digital raster graphics (DRG) maps at a scale of 1:24,000.

Use_Constraints:
Polygons represent the entire upstream area from each site, and therefore are 'nested' on top of each other. Some spatial analysis operations will not produce accurate results for nested polygons. This dataset is intended for archival of drainage-basin areas and boundaries.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Not applicable: there are no attributes at the geodatabase-level of GIS data organization.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Value: Not applicable.
Attribute_Accuracy_Explanation: Geodatabases have no attributes.
Logical_Consistency_Report:
The geodatabase contains a feature dataset that includes one topology. Two topology rules are used to constrain the spatial 'behavior' of features in the BasinLines feature class: (1) the BasinLines features are constrained to not have dead ends ("dangles"). (2) the BasinLines features are constrained to not overlap one another and that any lines forming an intersection in this feature class are split at the intersection to form a node point. Two additional topology rules ensure that lines in the BasinLines feature class are always coincident with a polygon boundary in BasinPolys feature class: (3) all features in the BasinLines feature class must be covered by a basin boundary in the BasinPoly feature class. (4) all basin boundaries in the BasinPoly feature class must be covered by a line feature in the BasinLines feature class.
Completeness_Report:
The geodatabase is updated as needed and is used to maintain an archive of basin boundaries, particularly those for active discharge-measurement locations in Colorado.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Basin boundaries are a combination of lines derived from the National Watershed Boundary Dataset (WBD) or by manually digitizing lines from USGS 1:24,000 digital raster graphics (DRG) source maps. Linework was derived by interpretation of DRG topographic contour information in order to correctly position the basin divide. Both the WBD and digitized lines inherit an error of +/- 40 feet (a topographic contour interval) according to National Map Accuracy Standards for 1:24,000 topographic map products. Whether originating from the WBD or from on-screen digitizing, boundary locations are interpretive and somewhat subjective even though general rules of hydrology were used (for example, natural water flows downhill). Interpretive accuracy of these data varies somewhat on the contour spacing in the original DRG source material. Digitizing of new lines proceeded generally at a scale between 1:6,000 to 1:10,000.
If the basin area differed by 3 percent from the published NWIS area, the basin was reviewed for accuracy, using the topographic maps as a guide for accuracy determination. Basins areas also were compared with those for the nearest upstream and downstream basin for consistency.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: 0
Horizontal_Positional_Accuracy_Explanation:
0 is used as a placeholder for unknown and variable horizontal accuracy.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Vertical accuracy is also assumed to be variable, depending on relief. Accuracy is assumed to be within one-half a contour interval (40 feet for most of Colorado), or 20 feet.
Quantitative_Vertical_Positional_Accuracy_Assessment:
Vertical_Positional_Accuracy_Value: 20
Vertical_Positional_Accuracy_Explanation:
20 feet - accuracy assumed to generally be one-half a contour interval; the contour interval for most topographic maps in Colorado is 40 feet.

Process_Description:
Basin delineation for the dataset occurred by copying lines or polygons from the WBD. Lines digitized from the 1:24,000 were added to connect the basin outlet site to the nearest WBD lines. Linework was reviewed by comparison to basin areas upstream or downstream from the new basin.
