Data Model Usage Guide
S-121 Theoretical Example Dataset (.XML) for ArcGIS
The following example was created for the purposes of illustrating one possible GIS implementation of the S-121 standard. The XML schema was created using fictional data, and should not be interpreted in any way as being the maritime limits and boundaries of any real state. As the schema was created for example purposes, at this time metadata has not been produced in conjunction with the XML shell. The S-121 project team strongly recommends that any geospatial information produced in a S121, or other standard format, have accompanying metadata, and further recommends that the Open Geospatial Consortium specifications for metadata be adhered to, as well as the ISO TC/211 international standards.
This example depicts, using the S-121 data model, the core Maritimes Limits and Boundaries of three different States. This example shows only part of the data model capacities, mainly how fully enclosed geospatial components are linked to the administrative components, and how the same extent can be shared between two or more parties (see the 2 joint development areas defined).
