oh_blocks

Format

A spatial features (sf) data frame with 5,596 features and 24 fields:

block_id

unique block identifier (integer)

block_key

unique block identifier (character), comprised of v{zone_version}{zone_key}{PROTRACTION_NUMBER}_{BLOCK_NUMBER}

block_type

one of either "lease" or "plan" depending on data source

zone_version

zone version from oh_zones containing the block

zone_id

zone id from oh_zones containing the block

zone_key

unique zone from oh_zones containing the block

PROTRACTION_NUMBER

the BOEM area defined by the roughly 2° longitude by 1° latitude containing up to 1,200 blocks. Computed using the International UTM Zone Numbering system, e.g. NJ is North (N); Lat 36-40° (J); 18 is UTM zone 18; and 02 is the 2nd of 12 possible maps

BLOCK_NUMBER

Each whole block is approximately 3 nautical miles (nm) by 3 nm. For renewable energy purposes only, blocks can be leased down to the 16th of a block.
