Description:

Abstract:

The World Vector Shoreline (WVS) dataset was developed by the National Geospatial-Intelligence Agency (formerly the U.S. Defense Mapping Agency - DMA) as a digital data file, at a nominal scale of 1:250,000 and referenced to the World Geodetic System (WGS-84) datum. The WVS is divided into ten ocean basin area files. This data layer is a subset of the eastern north Pacific basin region WVS dataset and provides a shapefile of Mexico and Central America.

Purpose:

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).

Supplemental_Information: Shoreline based on Mean High Water (MHW).

Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 1; ESRI ArcCatalog 9.1.0.722

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

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.

Logical_Consistency_Report:

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.

Completeness_Report:

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.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

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.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

There is no elevation data in the WVS product, therefore vertical accuracy is not applicable.

Source_Contribution:

The main source material for the WVS was DMA's Digital Landmass Blanking (DLMB) database which was derived primarily from the Joint Operations Graphics and coastal nautical charts produced by DMA. The DLMB data consisted of a land/water flag file on a 3 by 3 arc-second interval geographic grid. This raster database was converted into vector form to create WVS and explains the 3 arc-second stepping interval apparent in the coastline when plotted out at high scale. For areas of the world not covered by the DLMB database, the shoreline was taken from the best available hard copy sources at a preferred scale of 1:250,000 (or up to 1:125,000 where the source data allowed).

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.

Process_Description:

Program 'getcoast' was used to extract the vector coastline information from the eastern north Pacific ocean basin World Vector Shoreline dataset.

Process_Description:

The vector text data files were imported into a vector segment in the PCI database. The WVS data for Mexico and the Central America region was extracted from the eastern north Pacific region and stored in a new vector segment of the PCI file. Vector polyline information were visually checked and verified to correct overshoots and undershoots and verify closures.
