This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.
Sequential unique whole numbers that are automatically generated.

This ArcView shapefile may be used as a general basemap data layer to illustrate Mexico and the Central America region and may be utilized in any Geographic Information System (GIS).
Review, International Hydrographic , 1990, World Vector Shoreline for the eastern north Pacific ocean basin.
The DMA WVS datasets were compiled into separate 'coast' format data files for use with the USGS Coastal and Marine Geology Program cartographic plotting program MAPGEN during the 1980's. These 'coast' format files were the source to retrieve the WVS datasets and is the result of what is presented here.

Data sources produced in this process:
Attributes were labeled by visual identification. Country name, sovereign and island name were identified from various map sources. Islands may be misidentified as to assignment of name and sovereign. The island attribute is incomplete.
The absolute horizontal accuracy requirement for WVS data is that 90% of all identifiable shoreline features should be located within 500 meters (i.e. 2mm at 1:250,000) of their true geographic position with respect to the WGS-84 datum.
There is no elevation data in the WVS product, therefore vertical accuracy is not applicable.
This is a subset of the World Vector Shoreline eastern north Pacific basin region. The polyline vector information representing the shoreline of Mexico and the Central America region were extracted to create an ESRI shapefile format data layer. This data set is intended to be a relatively accurate and medium-resolution representation of shoreline for use in GIS applications.
Polygon topology present. No duplicate features are present. All polygons are closed, and all lines intersect where intended. No undershoots or overshoots are present.
The shapefile was processed via a Build and Clean operation. This request verifies and enforces the correctness of shapes.
No additional checks for topological consistency were performed on the data.
