The "Pesticide Use Limitations - 9th District Court Order" application provides users with interactive Geographic Information System (GIS) functionality using spatial data from a variety of sources. The application allows you to view spatial data for any county in Washington, Oregon, or California. A detailed map of rivers and streams for your window location is created, with those rivers or streams containing limitations on use of designated pesticides highlighted. You can manipulate and change the map that is displayed by zooming in, zooming out, identifying features, re-centering the map, and displaying a locator map. This On-Line Help module provides additional information on specific features of the Pesticide Use Limitations application.
To determine specific waters and usage limitations that may apply to a particular pesticide, choose a state and the specific pesticide active ingredient you intend to use. Then, click the "Submit" button.
Counties in which court-ordered limitations are imposed on streams for the selected pesticide are shaded. You can either click on a county to get information on Pesticide Use Limitations for stream segments found in that county, or select another pesticide from the pesticide drop-down menu (located on top of the state map) to highlight the counties in which limitations for the selected pesticide have been imposed.
Once in the interactive mapper, you can use the Select Pesticides drop-down menu (located next to the map in the middle right corner) to redraw the map based upon use limitation information imposed for each pesticide on waters in the county. The map will display water segments (in red) pertinent for the selected pesticide.
After making your selection, click on the 'GO' button next to the menu to have your information displayed on the map. Once the map has been redrawn, a legend will appear under the 'Map Features' header providing additional information about the newly created map.
The Zoom In selection allows you to view the map two times as close in than the size currently displayed on the screen. This is done by clicking on the toggle button and then clicking on the area of interest on the map. The map will then be centered on the point of interest you clicked on in the main map display.
The rubber band box can also be used to zoom in. To use the rubber band box, place your mouse on the map and then drag the red box that appears to your desired height and width.
The Zoom Out selection allows you to view the map two times further out than the size currently displayed on the screen. This is done by clicking on the toggle button and then clicking on the area of interest on the map. The map will be centered on the point of interest you clicked on in the main map display.
The Identify option allows you to click on a specific feature within the selected layer to see its name and other pertinent information. First, click on the Identify toggle button, then select the feature you want to identify from the "Select a feature" drop down box.
For example, if you want to identify a displayed Segment with Limitations, you need to click on the Identify toggle button and select the appropriate layer from the drop down box. Use your mouse to click on the point of interest; the map will regenerate, the point will be highlighted, and the name will appear on the map and under the main map display. If the name is hyperlinked, you may click on the name to view all pesticides that have court-ordered usage limitations for the selected stream segment.
The Recenter selection provides a view of a specific area on the map. To use this feature, click on the Recenter toggle button. You must then click on the desired area on the map. The map will be centered around the point of interest you clicked on the main map display.
To change your view of the map, click on the blue arrow in the direction that you want to go. The map will shift (pan) in that direction.
The Redraw Map button allows user to change and refresh the currently displayed map. This button is located at the top and bottom of the legend, which appears to the right of the main map display. Beneath the top redraw map button are located the layer controls which include two types of buttons, a checkbox for turning layers on and off and a box with a plus/minus symbol for hiding/displaying legend options. You can toggle on and off the layers that are displayed by clicking on the plus or minus sign next to Water Features, or Political Boundaries. Click on the checkbox (square) to make your layer selection for display; you may click on multiple checkboxes to select more than one layer, and you may de-select by clicking on the checkbox again.
Your map can display the following layers:
Click on the Locator Map checkbox to view a locator map within your window.
The Locator Map option allows you to display a higher level map that shows your window location.
The Legend option allows you to remove from view the mapping features on the right hand side of the map that have not been turned on. To use this option, click on the Legend check box. To redisplay the mapping features, just uncheck the Legend check box.
