This is a vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.01. Longitudes are given to the nearest 0.01. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is Geodetic Reference System 80.
The semi-major axis of the ellipsoid used is 6378137.
The flattening of the ellipsoid used is 1/298.257.

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.

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.

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.
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.
