Description:

Abstract:

This GIS overlay is a component of the U.S. Geological Survey, Woods Hole Science Center's, Gulf of Mexico ArcView GIS database. The Gulf of Mexico GIS database is intended to organize and display USGS held data and provide on-line (WWW) access to the data and/or metadata. Additional GIS overlays downloaded from the WWW, such as the one described here, are also included in the Gulf of Mexico GIS database. Attempts to properly attribute such GIS overlays with the WWW address and data compilers has been made.

Purpose:

Contains the information that defines the Federal lease blocks for the Gulf of Mexico OCS region.

Supplemental_Information:

The Minerals Management Service 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.
