Step 1: Choose a Focal Area
The tool provides high-resolution, coast-to-coast coverage of the lower 48 U.S. states and Alaska.
- You can select one of the predetermined Focal Areas:
- Contiguous U.S.
- Alaska (also Tongass National Forest, National Petroleum Reserve, Arctic National Wildlife Refuge)
- Search for a location by name in the search box (lower right)
- Or use the“polygon tool” icon (lower right) to plot the outline of your own geographic area. Within your desired area, you can hold down the “Shift” key and click on individual land parcels to add them to your analysis.
