- Description:

- Abstract:
-
This feature dataset includes the three permanent feature classes in the geodatabase and the topology rules that govern their spatial behavior. A feature dataset also forces any feature classes inside it to have a consistent projection system, which is, in this case, an Albers-Equal-Area projection system. This geodatabase 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:
-
The feature dataset was developed in 2009 to contain feature classes for archiving new basin boundaries developed by the U.S. Geological Survey (USGS) Colorado Water Science Center. The feature classes and topology rules in this geodatabase were generated for the purpose of determining acccurate drainage-basin areas for publication in NWISWeb and in the Annual WaterData Report.
This feature dataset contains three feature classes: BasinLines, BasinPolys, and Sites. It 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.

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.

-
- Attribute_Accuracy:
-
- Attribute_Accuracy_Report: Not applicable because feature datasets have no attributes.
- Quantitative_Attribute_Accuracy_Assessment:
-
- Attribute_Accuracy_Value: Not applicable.
- Attribute_Accuracy_Explanation:
-
Feature datasets have no attributes, but the "XY Tolerance" set for the feature dataset, BasinsFD, matches that used in the versions of the National Watershed Boundary Dataset (WBD) that are in a UTM projection. The XY Tolerance used (based on the WBD) is 0.001 meters.
- Logical_Consistency_Report:
-
Feature datasets alllow inputting of topology rules to govern the spatial interrelations among any datasets contained in the feature dataset. Topology ensures that features across the entire extent of a dataset are consistent in their 'spatial behavior' and spatial interrelations. Topology can be set only for feature datasets, and this feature dataset includes one topology, called BasinsFD_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:
-
Regarding the topology rules, there are presently no exceptions to the rules saved in the topology. All new basins are tested as they are added to this archive to check that they conform to these rules.

Basin boundaries are a combination of lines derived from the National Watershed Boundary Dataset (WBD) or by manually digitizing lines from 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 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 and 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 were also 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-scale DRG topographic maps were added to connect the basin site to the nearest WBD lines. Areas for new basins were reviewed by comparison to areas for basins for sites upstream or downstream from the site used to delineate the new basin.
