Multnomah County • Portland Metro • City
Portland sits where the Willamette River meets the Columbia, on flat river terraces below the steep, forested Tualatin Mountains on its west side. Buttes such as Mount Tabor and Rocky Butte rise on the east side.

Sun and terrain in Portland
South-facing slopes get the most sun, especially in winter when the sun stays low. North-facing slopes and the floors of narrow valleys can stay in shade for much of the day. The Sunlight tool shows where the terrain around Portland casts shade, and Slope & Aspect shows which way each slope faces.
The winter solstice on December 21 has the lowest sun and the longest shadows, and the summer solstice on June 21 has the highest sun. Compare the two to see how a site changes through the year.

About the elevation data for Portland
The tools read the USGS 3D Elevation Program (3DEP) bare-earth elevation model, built from airborne lidar: 3.3 ft per pixel where lidar has been flown, with buildings and vegetation removed, and elevations above NAVD 88. Most of Oregon’s lidar was flown through the Oregon Lidar Consortium, run by DOGAMI. The data suits:
- GIS users: Import contour lines straight into QGIS, ArcGIS or other GIS software
- Architects, engineers and surveyors: Terrain for site design and planning
- Hikers and trail runners: Plan routes with accurate elevation profiles
- Property buyers and rural landowners: Check slope, sun and drainage before you buy or build
- Teachers: Geography, geology and earth science lessons
- 3D printing: Make a physical terrain model of Portland
USGS 3DEP data is in the public domain, so it can be used commercially. Every file you download from this site still names its sources. The elevation on this page is the bare ground at Portland’s point in the USGS Geographic Names Information System, rounded to the nearest 100 ft, and can differ from signs and printed maps.
