It primarily consists of lines and polygons collected as part of the State Addressing and Mapping project. As such, most of the data is current as of the year 2003. This dataset also contains features from the high resolution (24,000 Scale) NHD dataset. See Data Quality - Process Step(s) for more information. Purpose: This is an iterative dataset produced as part of the development of local resolution NHD in West Virginia. It is not intended to be a final dataset for hydrologic modeling. It is geometrically complete and contains only basic, skeletal attributes.

Lineage: Process_Step: Process_Description: Data acquired from West Virginia State Addressing and Mapping Board. Process_Date: 20060401 Process_Step: Process_Description: We visually compared the 4,800 and 24,000 scale lines to determine the completeness of the new data. These comparisons revealed that a significant portion of the streams represented in the high resolution NHD had no corresponding feature in the 4800 scale data. To remedy these discrepancies, the WVGISTC compared the data statewide and, using ancillary data such as aerial photography and coal mine permit boundaries, we included those 24K arcs that were missing from the 4,800 scale data but appeared hydrologically unchanged. From here, using the existing attributes, we standardized the attribute information, topologically enforced the vector data, divided the data into 8-digit watersheds and edge matched all lines and polygons.

Line files include all lines, including polygon boundaries. Both line and polygon shapefiles contain basic attributes. Of most importance are the 2 major/minor DLG pairs, which describe the basic category of each feature. We have also included a text field that describes the value of each major/minor pair set. These values were derived from provided attributes in the case of 4800 scale data and from the FCODE value of 24000 scale features. The attribute SCALE describes the source of the feature. Those features with the value 4800 in the SCALE field were collected by the West Virginia Statewide Addressing and Mapping project from 2003 aerial photography. Those features with the value of 24000 were added to the dataset from high resolution (24,000 scale) NHD due to the lack of a corresponding line in the 4800 scale data.
