About Aerial Detection Surveys
These maps are based on cooperative aerial surveys conducted by Forest Health staffs of the Oregon Department of Forestry, Washington Department of Natural Resources, and the USDA Forest Service Pacific Northwest Region.
Each map is a 1 to 5 MB pdf file - select a year (above), then click on a quad to view a map. You can save the file to your local disk and view/print as needed. 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.
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.
