| Open-File Report 97–470 A: Introduction |
The CD-ROM was compiled according to the methodology developed by the
U.S.
Geological Survey's World Energy Project . The goal of the project
was to assess the undiscovered, technically recoverable oil and gas resources
of the world and report these results by the year 2000. A worldwide
series of geologic maps, published on CD-ROMs, was released by the U.S.
Geological Survey's World Energy Project during 1997 - 2000.
Specific details of the data sources and map compilation are given in
the metadata files on this CD-ROM.
These maps were compiled using Environmental Systems Research
Institute Inc. (ESRI) ARC/INFO software. Political boundaries and
cartographic representations on this map are shown (with permission)
from ESRI's ArcWorld 1:3M digital coverage: they have no political significance
and are displayed as general reference only. Portions of this database
covering the coastline and country boundaries contain proprietary property
