Instructions

For a selection using polygons select 'Polygon' from the Area Selection menu and draw the desired area by polygon directly on the map. When done drawing the polygon, click the first point or double click the desired last point. You can always delete your current selection using 'Clear Canvas'. Changing the Area Selection from 'Polygon' to 'Map Extent' will also delete any former polygon input.

For a selection with map extent select 'Map extent' from the Area Selection menu and zoom to desired area and submit.

When you are satisfied with your input click "Submit" to generate the results.
