Contiguous zone (12-24M)
This zipfile contains the boundaries and limits of the contiguous zone of the Netherlands on the North Sea. This is the area that lies between 12 and 24 miles off the North Sea coast. More information on this zip file is available below the download.
Specifications of the geographic data
The data are expressed in the geodetic datum WGS84. For this application, it may be assumed equal to ETRS89 and NAD83.
Each zip file contains three data formats:
- ESRI SHAPE for ArcGIS (extensions DBF, PRJ, SHP and SHX, including metadata in XML format).
- KML for Google Earth (extension KML).
- A simple ASCII format (extension DAT). This format contains degrees, arc-minutes and arc-seconds for first geographic latitude and then longitude.
Reduction of density
The curved shape of the normal baselines and the limits requires a high nodal density. For some applications, lines with less nodes are necessary. The TSP program reduces nodal density of ASCII files with a DAT extension.
