Geographic Mapping Data
in Digital Format
The geographic data are built from
the Technical Information
Management System (TIMS). TIMS is the computerized information system that
automates all business and regulatory functions of the Offshore Minerals
Management program of the Minerals Management Service (MMS).
TIMS consists of
two separate databases: an attribute database and a spatial database.
The
attribute information for offshore activities is stored in the
TIMS database. The spatial database is a combination
of the ARC/INFO and FINDER databases and contains all the coordinates and
topology information for geographic features. The attribute and spatial
databases are interconnected through the use of common data elements in both
databases, thereby creating the spatial datasets.
The data in the mapping files are made up of straight-line
segments. If an arc existed in the original data, it has been replaced with a
series of straight lines that approximate the arc. The Gulf of Mexico OCS Region
stores all its mapping data in longitude and latitude format. All coordinates
are in NAD 27.
Data can be obtained in three types of
digital formats:
-
ASCII:
American Standard Code for Information Interchange is plain text format where
a string of 7 binary digits represents each character.
-
E00: An ArcInfo
interchange file format used for system independent exchange of geographic
information system (GIS) coverages and associated data.
-
DXF: Drawing Exchange File is a two-dimensional graphics file
format supported by PC-based CAD products. DXF data includes no topology.
Please read our disclaimer prior to downloading files.
