Oregon/Washington Aerial Detection Survey (ADS) Data Review Tool


Browser_app OR/WA ADS Data Review Map


Forest Health aerial survey detection specialists collect geospatial data layers of forest insect and disease damage throughout the Pacific Northwest. After collection, these data are reviewed by local pathologists/entomologists/silviculturalists for verification of damage agent and host calls made by the aerial surveyors. Region 6 (OR/WA) Forest Health Protection personnel then compile these review comments and incorporate them into the final data layers.

This web browser map tool is designed to enhance this review process by delivering the survey data weekly to the local specialists, giving them a near-real-time look at damage detected from the air. The aerial survey data are posted on our GIS data server and the web browser map application connects to that server and displays the data with several possible basemaps and boundary layers.

Using the OR/WA ADS Data Review Map
Click the above link to open the map. The map will open in your web browser and will require no additional software. Zoom into an area of interest on the map by using the slider bar at the top left of the map, or hold down the shift key and drag a box with your mouse around the extent of interest. Zooming can also be done using your mouse scroll wheel. Pan the map display by holding the left button down on your mouse. Different Basemaps (Imagery, Street Map Topographic Map) can be displayed by using the buttons on the bottom right of the map display.

Visibility of the layers in the map can be controlled using the Content Panes at the right of the browser page. Activate a Content Pane by left clicking the title bar of the pane with your mouse. Map layers can be clicked on/off using the checkboxes in the Content Panes. Layers are organized logically in four Content Panes, e.g. Oregon survey data are in the 'Oregon ADS' pane, reference boundary layers are in the 'Boundary Layers' pane, etc. The most recent ForWarn layers are also included for reference.

NOTE: ADS damage polygons will appear at scales of 1:1,500,000 or more (approx 250 miles East-West).

The Tools Content Pane contains utilities to interact with the map. The Opacity Slider allows you to scale the visibility of a map layer by selecting a displayed map layer from the pull-down list and adjusting the slider tool. A pop-up window displaying attributes of a specific damage polygon can be displayed by using the Identify tool. First, select the damage polygon map layer from the pull-down list for the Identify tool. Next, right click on a polygon in that layer and the pop-up window will display. The Bookmarks tool allows you to save spatial extents for future reference. Zoom to an area of interest and click the 'Add Bookmark' text and give the bookmark a name. The bookmarks are saved locally to your PC browser. Currently it is not possible to email or otherwise transfer bookmarks.
The 'Export Map' tool will create map layout of the current extent in the selected graphics format. Use the pull-down menu to select the format (jpg, pdf, etc), then select the template using the pull-down menu associated with the 'Print' button. Clicking the 'Print' button produces a basic map-only layout. When the export is complete, click the 'Printout' link to open the exported map in your browser. The exported map will contain the legend for the 'Active Layer'. Right click on the exported map in your browser and select 'Save as..' to copy the map graphics file to your local drive.
