Description:

Abstract:

Contains information that defines the composite polygons of the areas for the Gulf of Mexico region. This file is based on the OCS Marine Survey Group Official Protraction Diagram (ODP). Each offshore area is defined by an API Number corresponding to those in the API Bulletin Number D12A.

Purpose:

Outlines of the Protraction Diagrams for the Gulf of the Mexico OCS region.

Supplemental_Information:

The MMS Gulf of Mexico OCS Region stores all its mapping data in longitude and latitude format. Therefore all dumps or files produced will have the coordinates stored in lon/lat format . If the official coordinates (x,y format) are needed, then the Oracle dump of the data must be purchased from MMS.
