Instructions on How to Operate DownScan

Step 1: Draw your route

There are three ways to do this.

1. In the upper right corner of the map you will see a Search box. Enter your origin point address in the search box, and click the magnifying glass icon. DownScan will automatically plot this address as a point on the map. Erase the first address in the search box, enter your destination or next point address in the search box and click the magnifying glass icon. DownScan will draw a route between the two points, and any subsequent points you add using the search box.
2. Uncheck the “Set Point” box above the upper left column. Then, navigate and scroll over the map to locate your point; check the “Set Point” box; then, left click to set your point. Uncheck the “Set Point” box before proceeding to navigate to your next point on the route or destination point. Check the “Set Point” box. Then navigate again to your next or final point, check the “Set Point” box, and left click to set your next or final point. DownScan will automatically draw a route line between all points you scan- locate and set.
3. Enter coordinates of the origin point into the “Add Coordinates” box in the left hand column. Be sure to include the minus sign at the front end of your longitudinal coordinate. You won’t see the coordinates in the box as you type, but when you click on “Add,” this and any additional points will display in a list. Build your route by typing the coordinates sequentially into the Add Coordinates box. DownScan will automatically plot points in the list into a route on the map.

You can use any, or all of these methods, sequentially to set points in a specific route. As you set points, DownScan will automatically draw a route among those points, in the order you set them. If you make a mistake, or want to change what you’ve already set, no worries. Just click the “Undo” box, and DownScan will erase points one at a time in the reverse order to which you set them.

Step 2: Select or describe your aircraft

Do this by making a selection from the dropdown menu in the left hand column, or entering the physical and operational characteristics of your custom or specific vehicle.

Step 3: Calculate the DownScan values for your route

Do this by clicking the “Submit” button beneath the map. DownScan will calculate and display, under the map, the Property Risk (dollars), Human Risk (dollars), and the Exposure Risk (numbers of people) associated with your defined route.
