Title:
U.S. Coast Guard Marine Safety Office (MSO) Zones Encompassing Louisiana, Geographic NAD83, LOSCO (2000) [zongeog3dbmso]
Description:
Abstract:
This is a polygon dataset delineating the boundaries of the three U.S. Coast Guard Marine Safety Office (MSO) zones that encompass the state of Louisiana. The MSO zones are: New Orleans, Morgan City, and Port Arthur.
Purpose:
Delineates the jurisdictional boundaries of MSO zones. For the purposes of responding to an oil spill emergency (a LOSCO concern) it identifies the MSO office to be contacted for assistance that is dependent on the area of Louisiana in which the spill occurs. This data set is appropriate to identify MSO zones pertinent to Louisiana. It is not appropriate to identify the MSO zones pertinent to other states.
Supplemental_Information:

LOSCO gratefully acknowledges the Minerals Management Service for providing the Exclusive Economic Zone component of this data set and the USGS for providing the county boundary and hydrography data necessary to delineate other parts of the MSO zone boundaries.

Data_Quality_Information:

Logical_Consistency_Report:
Topological and labeling tests, and attribute statistics were obtained with a quality assurance AML (qa_report.aml). This report is used to expose inconsistencies and problems in the data and its attributes, and to verify correction of those errors when corrections are possible. No errors were detected in labeling or topology.

These data represent what the data processor (3001, Inc.) believes was intended by the boundary description from the Code of Federal Regulations, even though that description is, in cases, logically inconsistent, discontinuous, or ambiguous.

Completeness_Report:
Includes the MSO zones which cover Louisiana except for a sliver of the Mobile MSO covering a small piece of southeast Louisiana offshore territory. The northern boundary of the New Orleans MSO was constructed somewhat arbitrarily because the description in the Code of Federal Regulations was not clear.

Provided delineation of state shoreline (sea/land boundary) for Texas and Mississippi. The sea/land boundary, in combination with lines of fixed longitude, provide several inflection points for the MSO zone boundaries. The shoreline was used as a buffer object to build a boundary portion at 10.3 nautical miles from the coast. Provided delineation of county boundaries when the MSO zone boundary followed them.

Provided line (HYDROGL020) and polygon (HYDROGP020) water features defining portions of the MSO zone boundaries, namely the Trinity River (TX) and Lake Livingston (TX).
Process_Step:
Process_Description:
The CFR description was used as a guide to produce those portions of the zone boundaries defined by lines of longitude and points of latitude and longitude. The CFR description was used to select those counties whose boundaries comprised a portion of an MSO boundary from the COUNTYP20 dataset. The COUNTYP20 data set was used as a buffer source to produce a portion of MSO zone boundary defined as 10.3 nautical miles from the coast, and the means to define turning points in the boundary at lines of fixed longitude. The Trinity River was selected from the HYDROGL020 data set and Lake Livingston was selected from the HYDROP020 data set. The arcs comprising those features selected (or built) as described above and the EEZ data set were attributed to encapsulate the source name.

The arcs described above were placed into a common data set and edited to remove all arc segments extraneous to the MSO zone delineation. Short arcs were constructed as necessary to bridge gaps between the component data. A long arc was constructed at 30.5 degrees north latitude to close the New Orleans MSO zone to the north. This was necessary to resolve incomplete description of that boundary in the CFR source and does not impact the delineation of MSO zones across the state of Louisiana.

The arcs were built into polygons and densified with intermediate vertices at 1 minute (0.01667 degree) intervals.
