Viewing & Printing Quad Maps

After you have opened a map by clicking on a rectangle (above), you can save the file to your local disk and view/use/print it from there. Zoom views can be printed on 8.5 x 11 printers, while full maps are best printed at 36" x 36" on a full scale plotter.


Aerial Detection Surveys

The above map is based on annual cooperative aerial surveys conducted by Forest Health Protection staffs of the Oregon Department of Forestry, Washington Department of Natural Resources, and the USDA Forest Service Pacific Northwest Region.

The maps can also be used with the Avenza PDF Maps Mobile App. This application is a geospatial reader for Apple and Android mobile devices and allows for interaction with spatially referenced maps to view your location, record GPS tracks, add placemarks, and find places.
