Description
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.
