Suitability Index Guided Tool
Instructions
This is a beta version of the Suitability Index Guided Tool, please contact Jim Perdue and/or Tim Young with any questions, comments or suggestions. Thank you in advance for your participation.

Please go through Step 1 and 2 to select and review the Suitability Analysis factors.
Select the "Forest" tab in Step 2 and the suitability results for Forest land use will be displayed on the map.
Select the "Agricultural" tab in Step 2 and the suitability results for Agricultural land use will be displayed on the map.
In Step 3, enter a Zip Code (sets the spatial center of the suitability index search) and select a one-way truck driving distance (sets the spatial extent of the suitability index search).
Note the results are displayed on the map at a ZCTA resolution, not a Zip Code resolution. The map displays ZCTAs boundaries from the 2010 Census. You can learn more about ZCTAs by following this link.
The ZCTAs (if any) corresponding to your selections in Step 2 will be displayed on the map.
If you select one-way truck driving distance > 40 miles, it may take some time to display the results on the map as the number of ZCTAs increase dramatically with the driving distance radius.
If you click on one of the ZCTA on the map, this ZCTA will be highlighted, if you click once more on the same ZCTA, an information window will appear, displaying several socio-economical and landscape factors.

Step 1:
  • Forest
  • Agricultural
Select Exclusion Factors for Forest land use
According to the litterature, the following criteria should be selected to exclude areas that are unsuitable for forest land uses. Though it is not recommended, you may leave the checkboxes unchecked.
Select Exclusion Factors for Agricultural land use
According to the litterature, the following criterion should be selected to exclude areas that are unsuitable for agricultural land uses. Though it is not recommended, you may leave the checkbox unchecked.
