Commercial Fishing Blocks - R7 - CDFW [ds3093]

The basic 10 minute grid was created using the ARC/INFO generate fishnet command. The input coordinates were in decimal degrees and the resultant coverage was subsequently projected into Teale Albers. The coastline derived from the 1:100K hydrology was incorporated to the 10 minute grid. The trawl logbook developed by the Pacific Fishery Management Council, the States of Washington, Oregon, and California, and the National Marine Fisheries Service was used as the reference. Many grids, therefore, are 30 x 30 or larger or are partial representations of a 10 grid. Islands, bays, deltas and estuarine waters that occurred in the 1:100K hydrology were included in the coverage. Any features not in fishable waters were given an ID of zero. All other features correspond to the ID shown in the Trawl Logbook. The field containing the ID is called block10-id.
