Gulf of America Offshore Geographic Mapping Data

Geographic mapping data from the Gulf of America OCS Region, built from the Technical Information Management System (TIMS). The data integrates an attribute database with a spatial database containing coordinates and topology for features like blocks, leases, and units. It is available in multiple digital formats including interactive ArcGIS web maps, Shapefiles, and Geodatabases.

Use Cases

• Analyze spatial relationships between features like Block, Active Lease, and Unit polygons for offshore resource management.
• Create interactive web maps using the ArcGIS format to visualize and query geographic layers such as Lease Line and Protraction areas.
• Perform geospatial analysis on Clipped polygon data stored in Shapefile or Geodatabase formats using NAD 27 coordinate reference system.

Strengths

• Data originates from the authoritative Technical Information Management System (TIMS) managed by the Department of the Interior.
• Offers data in three distinct digital formats (ArcGIS interactive maps, Shapefiles, Geodatabases) catering to different user needs.
• Spatial data is explicitly stored in the NAD 27 coordinate reference system, providing a consistent geographic framework.

Limitations

• Geographic coverage is limited to the Gulf of America OCS Region, which may not be suitable for analyses of other offshore areas.
• Arcs from original data are approximated with straight-line segments, potentially reducing geometric precision for curved features.
• The dataset's update history and temporal coverage are not specified in the provided input.
