Multipurpose Marine Cadastre

Geospatial data and tools for marine spatial planning

An increasing demand for alternative energy is focusing attention offshore. The Multipurpose Marine Cadastre, a marine information system for the outer continental shelf and state waters, is addressing these issues by providing direct access to authoritative marine cadastral data, and by demonstrating how boundary and other data are being used to support decisions on ocean uses.

Data Portal

Data are available in several common file formats such as ESRI and KML, and as Web services.

View Data Portal

U.S. Marine Cadastre Data Viewer

Data can be viewed through both ArcIMS and Google Earth applications. If using the Google Earth viewer, please download the Google Earth software. Options are also available to download data from their authoritative sources.

Example Uses

Alternative Energy Viewer
This data viewer contains marine cadastral and other data that have been identified as critical to alternative energy siting and research. Because of the large amount of data and links to external map services, the data are viewable through an ArcReader application. If you do not already have ArcGIS 9.x ArcReader installed, please download and install ArcReader before downloading the Alternative Energy Viewer.

Alternative Energy Viewer

Please note: The pmf file will only work with ArcReader 9.2. Please check back soon for a 9.3 version.

Web Services
Find Open Geospatial Consortium (OGC) Web services for a select set of data in the Data Portal. Website updates will be made as additional data become available as Web services.

Technical Services

Web Mapping and Support Services
Interested in building your own mapping application? Standard templates and documentation for visualization and analysis of geospatial data are available for your organization. Whether you are a user or provider of marine cadastral data, the Multipurpose Marine Cadastre project team can provide assistance in acquiring, using, and sharing offshore boundary data. Technical support is available on a case-by-case basis. A standards and best practices document will be completed by the end of 2009.
