MarineMap is a web-based decision support tool for open and participatory spatial planning in the marine environment, it is particularly helpful when there is the need for simultaneous consideration of multiple objectives and associated trade-offs.

In July of 2010 Ecotrust was retained by the Oregon Department of Land Conservation and Development to lead the development of Oregon MarineMap to support the State’s marine spatial planning efforts. MarineMap is a product of the MarineMap Consortium, which is composed of developers at the University of California Santa Barbara, Ecotrust, and The Nature Conservancy.

Oregon MarineMap development will support the on-going public process to update the Oregon Territorial Sea Plan (TSP), which requires the State “to conserve marine resources and ecological functions for the purpose of providing long-term ecological, economic, and social value and benefits to future generations”. Goal 19 requires the State “to protect and encourage the beneficial uses of ocean resources such as navigation, food production, recreation, aesthetic enjoyment, and uses of the seafloor—provided that such activities do not adversely affect the resources protected”.

Data LayersAs part of the OCMP's support work for the various public processes on-going in the Oregon territorial sea, the following list of data sets has been assembled from a variety of public, academic and other research sources.

At the moment, the majority of the data available below is available in GIS shapefile format. We are working to also make many data sets available as KML, so that they are visible in Google Earth. To browse data in a Google Earth interface please visit the Oregon MarineMap project.

Several help videos have been produced to assist users to become familiar with the MarineMap tools and provide background and information about the program capabilities.
