To zoom in to an area, use the zoom bar on the left side of the map or the wheel of your mouse. To move around the map (pan), click on the map and drag.

To select Projects, use the 'Draw Polygon' button below.  Click on the map to form the beginning of the polygon and move the cursor to draw the selection area.  Release the mouse to finish. The map will be queried for all Treatments that intersect the polygon.
Hint: Zooming in will speed up your search.
