Description:

Abstract:

This GIS overlay is a component of the U. S. Geological Survey, Woods Hole Field 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.

Purpose:

This ArcView GIS layer is intended as a backdrop to the Gulf of Mexico area map. It contains the U.S. state boundaries in a polyline format.

The World Data Bank II political boundary information (state, coastline and international boundaries) were used to generate a vector dataset for the United States Gulf of Mexico coastal state boundaries.

Process_Step:

Process_Description:

The World Data Bank II coastline information has been stored in a format for use with the U.S. Geological Survey's MAPGEN prorgam. The vector latitude/longitude coordinates were extracted from from the Mapgen file with the area coordinates of -99.5, 31.1 and -79.5, 22.5. This retrieval was done for the U. S. state boundaries, coastline and international boundaries creating three ASCII files. The three individual files were combined to create one ASCII data file.

Process_Step:

Process_Description:

The ASCII file generated from the MAPGEN coast files were imported to PCI Remote Sensing Software's Imageworks program. The vector information was then checked for digitizing errors using PCI's Imageworks. Errors found from digitizing overshoots and undershoots in the original digitizing were corrected. All polygons were checked for closure. The corrected segment was exported in the ARC export format (usstates.e00) with the nodes recorded as latitude/longitude coordinates in decimal degrees.

Process_Step:

Process_Description:

The ARC export file, usstates.e00, was imported to ARC as coverage usstates. No clean was applied to the dataset as it has been verified clean in the previous processing steps. The ARC polygon coverage was created and a new field, state, was added to the attribute table. Polygons were grouped together and the table field was updated by identifing the state name in the added field.
