20240227 vector digital data https://wildlife.ca.gov/Data/BIOS https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/3100_3199/ds3153.zip These cells divide the 10-minute (10‘) grid or California trawl (Cal-Trawl) Blocks that are used in commercial fishing into 1-minute (1’) boxes. The California Recreational Fisheries Survey (CRFS) uses these Block-Box cells (commonly called Microblocks) as a reference for anglers to report location of recreational catch and effort data. The 1' Microblocks in this dataset extend inland to include many coastal areas, estuaries, and bays.Attributes:NM_INDEX: Unique identifier for each Microblock. Format is (10’ minute Block – 1’ minute Box). BLOCK10_ID: Identification number of the larger 10-minute Cal-Trawl Block.BLOCK1_ID: Numerical ID representing the number of the 1-minute box dividing each Cal-Trawl Block.X: Longitudinal centroid of the Microblock.Y: Latitudinal centroid of the Microblock. A systematic polygonal grid that divides the coastal waters of California into 1 minute latitude-longitude cells (approximately 1-by-1 nautical mile) which are used by the California Recreational Fisheries Survey (CRFS) project to gather recreational fisheries information statewide. Blocks are clipped to the California shoreline. In the survey data, these cells are referred as block-boxes, but more commonly they are referred to as Microblocks.
