Process_Description:

A. Coverage creation (Jason Seifert, NOHRSC, 981117) Compiled in Arc/Info using whatever format of the most recent data were available for each region (RFC). IHABBS (Integrated Hydrologic Automated Basin Boundary System) generated basins were received in .gen/.att format (ARC/INFO generate and associated text attributes) from AB, CN, LM, MA, NE, and WG. The remaining source data were digitized by RFCs using various map sources and software packages. Some data were digitized at NOHRSC prior to 1994. Accuracy and precision from one region to another is highly variable. Basins for some regions are extremely crude and not highly accurate. At NOHRSC we manually imported and edited the data from each region to correct errors and remove all edge-matching and "sliver polygon" problems. The "truth" against which the edited product was compared with was the previous year's (1998) basin coverage and the IHABBS-derived RFC boundary coverage. Review comments from staff at NOHRSC and input from RFCs were used in resolving remaining discrepancies. Our intent and expectation is to improve this coverage through the increased use of IHABBS and further integration of IHABBS-generated basin boundaries. fields (specifically, the elevation attributes for all RFCs and the DESCRIPTION attributes for the non-IHABBS RFCs) were populated using data received separately from basin boundary data or gleaned from the 1998 gisrs database at NOHRSC. These values were matched to the appropriate basins using the SHEF_ID as a unique identifier. Instances of mismatches or missing data were rectified on an RFC-by-RFC basis. Consequently, complete data sets exist for SHEF_ID, RFC, and elevation fields. A complete data set exists for DESCRIPTION with the notable exception of basins in SERFC. Some of these "basins" are actually flood zones or water management districts with no corresponding english basin name. (JMS, 18 November 1998).

Process_Description:

Secondary_Process_Step (Ira Graffman, NWS, 19981217) The shapefile from NOHRSC was rectrieved, and those fields neccessary for AWIPS were retained. Centroids of the polygons were added as the lat/lon fields.
