Port of Portland GIS Open Data

Port of Portland GIS data is updated every Monday at 5:00am PST (if the file has changed from the previous upload). Metadata for each dataset is provided below.

If you're restricted to ArcGIS and need a Shapefile you can use the JSON to Features tool in the Conversion Toolbox in ArcMap (or better, just convert it in QGIS). If you don't know what a Shapefile is... probably best to turn the other way and run.

Data Disclaimer

Port of Portland geospatial data is gathered, maintained and primarily used for internal reference and analysis, and is only updated as resources permit. Geospatial data refers to data and information referenced to a location on the Earth's surface such as maps, charts, air photos, satellite images, cadastre and land and water surveys, in digital or hard copy form.

Geospatial data may be gathered and maintained by more than one person or department within the Port, and data distributed by one person or department may not reflect the most recent data available from the Port or from other sources. Port geospatial data is not intended for survey or engineering purposes or to describe the authoritative or precise location of boundaries, fixed human works, or the shape and contour of the earth.

The Port makes no warranty of any kind, expressed or implied, including any warranty of merchantability, fitness for a particular purpose, or any other matter with respect to its geospatial data.

The Port is not responsible for possible errors, omissions, misuse, or misrepresentation of its geospatial data.

Port geospatial data is not intended as a final determination of such features as existing or proposed infrastructure, conservation areas, or the boundaries of regulated areas such as wetlands, all of which are subject to surveying or delineation and may change over time. No representation is made concerning the legal status of any apparent route of access identified in geospatial data.
