Step 1 of 5 (choosing retrieval type and estimate type group)

Retrieval Type

The "State(s) retrieval" type is the default. You should only select the "Circle retrieval" type when the area of interest is a circular area around some point. If you choose the circle option you must also enter the latitude and longitude of the point center in decimal degrees (the latitude and longitude of Duluth, for example, is latitude = 46.78 and longitude = -92.12) and enter the circle radius in miles. A location's latitude and longitude can be obtained using Google Maps (opens in new window) (1. locate the point of interest using Google Maps, 2. right-click on the location, 3. Select "What's here?" to see the coordinates.).
Select state or circle retrieval

Please select the land basis from the drop-down list.

Please choose a numerator estimate group, and, for ratio estimates, a denominator estimate group.

Note: An example of a ratio estimate is "volume per acre" where net volume of live trees is the numerator and area of forest land is the denominator.

Numerator Estimation Group

Please select the numerator estimation group from the drop-down list

Denominator Estimation Group
