- Abstract:
-
This data set contains OCS block outlines in ESRI Arc/Info export
and Arc/View shape file formats for the BOEM Pacific Region. OCS blocks
are used to define small geographic areas within an Official Protraction
Diagram (OPD) for leasing and administrative purposes. These blocks
have been clipped along the Submerged Lands Act (SLA) boundary and along
lines contained in the Continental Shelf Boundaries (CSB) GIS data
files.
Because GIS projection and topology functions can change or
generalize coordinates, these GIS files are NOT an OFFICIAL record for
the exact OCS block boundaries. Only the paper document or a digital
image of it serve as OFFICIAL records.
- Purpose:
-
OCS blocks and other cadastre information the BOEM produces are
generated in accordance with 30 Code of Federal Regulations (CFR) 256.8
to support Federal land ownership and mineral resource management.
- Supplemental_Information:
-
The BOEM is making its existing cadastre data
available at <http://www.boem.gov/Oil-and-Gas-Energy-Program/Mapping-and-Data/Index.aspx> and on CD-ROM. These data
will include digital images of BOEM data at the regional, planning area,
Official Protraction Diagram (OPD), and Supplemental Official OCS Block
Diagram (SOBD) levels and digital spatial data in Arc/Info export or
Arc/View shape format at the regional or planning area levels.

- Logical_Consistency_Report:
-
Coordinates for OCS blocks and projected
boundaries are calculated quantities and have been defined to be correct
to 3 decimal places of a meter. The OCS block polygon coverage was
topologically cleaned with Arc/Info s CLEAN command using a fuzzy
tolerance of 0.000002 applied to the coverage in longitude/latitude
coordinates. The data was then converted to Arc/View shape files.
- Completeness_Report: All NAD83 Federal Pacific OCS blocks are shown.

OCS block corners are calculated
values to 3 decimal places of a meter in the TIMS database. However,
GIS functions which build topology, change projection, etc. may
degrade coordinate values, For that reason, these GIS files are NOT
an OFFICIAL record.

- Process_Description:
-
The source data for the OCS block coverage is a
theoretical mathematical derivation. In-house computer programs are
used to generate a grid of blocks for each appropriate UTM zone.
These blocks were clipped along the Submerged Lands Act (SLA) boundary
and along lines contained in the Continental Shelf Boundaries (CSB)
GIS data files to show only those blocks or portions thereof within
federal jurisdiction.
