Oregon Maps and Data

The Nature Conservancy has taken a close look at spatial data resources for Oregon’s ocean and coastal lands. The resulting report, Oregon Submersible and Submerged Lands Ownership and Leasing Spatial Data Assessment and Development (download pdf, 464k), reviews the available data in detail. In some cases, TNC obtained or created spatial data that is not currently available through the web (these are noted below). Please Contact Us if you would like access to this data.

GIS Portals

Oregon Coastal Atlas (web site). Internet map server and archive of over 3,300 geospatial datasets.
Oregon Geospatial Enterprise Office. (web site) Includes the Oregon Geospatial Data Clearinghouse (web page) with spatial data library, interactive mapping, and a list of Oregon map sites (web page). The site has a wide variety of GIS datalayers available for download or through on online data viewer. However, it does not include comprehensive data on parcel ownership or authorized uses in ocean and coastal waters.

Submerged Lands

The Nature Conservancy obtained a shapefile of the Oregon Territorial Sea through the GIS office at the Oregon Department of State Lands. The territorial sea overlies submerged and submersible lands. A similar representation can probably be derived from the downloadable layer below.

Data	Oregon State Boundaries.
Access	Download ESRI Arc/Info export file. (web page)
Detail	Includes both shoreline and seaward limit of state territorial waters. 2001.
Distributor	Oregon Spatial Data Clearinghouse.

Alternatively, one may view a representation of submerged and submersible lands online by turning on both of the following layers in the Oregon Coastal Atlas. Oregon’s coastal submersible and submerged lands are those areas of the coastal zone seaward of the shoreline.

Data	Hydrography.
Access	View online interactive map. (web page)
Detail	Streams, rivers, lakes, ponds and shoreline.

Ownership

Submerged Lands Parcels

The Nature Conservancy obtained from the Oregon Department of State Lands a shapefile showing Estuary Ownership as of 1997. Attribute data indicates private, state or other ownership. Data does not cover submerged or submersible lands along the ocean-facing coast. Specific requests to the Department of State Lands are necessary to obtain this data.

General Property and Parcel Data

Data	The Oregon Map.
Access	View interactive map and access PDF parcel maps. (web page )
Detail	Parcels and PDF parcel maps from all Oregon counties updated monthly or quarterly. As of September, 2007, no ownership or assessment information was available.
Distributor	Oregon Department of Revenue.

Public and Conservation Lands

Data	Public Land Ownership.
Access	Download ESRI shapefiles. (web page)
Detail	Shows fee-simple ownership by Federal, State, Tribal, County, and City agencies. 2003.
Distributor	Oregon Geospatial Data Clearinghouse.

Data	Land Management (Land Ownership and Land Stewardship).
Access	Download ESRI shapefiles. (web page)
Detail	Categorizes land by the general type of ownership. 1999.

Data	Oregon Marine Managed Areas.
Access	Download ESRI shapefiles and tabular data. (web page)
Detail	Boundaries of areas submitted by Oregon to the national Marine Managed Areas Inventory Database.
Distributor	National Marine Protected Areas Center, National Oceanographic and Atmospheric Administration.

Leases and Other Use Authorizations

Aquaculture and Shellfish

Working from hardcopy data at the Oregon Department of Agriculture, The Nature Conservancy developed a data layer showing aquaculture leases in Yaquina Bay. As of September 2007, The Oregon Department of Agriculture was reportedly digitizing all of the aquaculture leases in the state.

Other Use Authorizations

While there are approximately 400 waterways leases affecting submerged and submersible lands issued by the Oregon Department of State Lands , TNC found only limited, non-spatial data. The Nature Conservancy was able to obtain a shapefile of 208 permitted and unpermitted shoreline protection structures through the Oregon Department of Land Conservation and Development. The Oregon Department of Parks and Recreation, which reviews Ocean Shore Permits for such structures, has posted permit decisions dating from 2004 to 2007 on the web.
