The final maps show that there is an extensive amount of land highly suitable for switchgrass crops whether the factors considered are weighed differently or the same.
Considering slope to be the most important factor did cause the magnitude of areas to become less suitable but the overall amount of area that was considered highly suitable is still similar to the all equal map.

The most suitable area looks to be near the center of the inset in both the equally and unequally weighted maps.


Sources of error:

• Soil data was from scale of 1:1000000 whereas the DEM and Landcover data were of 1: 250,000, thus for the soil data to be rasterized to the same cell size (75m) the data was more generalized than the other two rasters.

• Since the landscape and soil data were not continuous data the normalization of them was subjective and changing the values of their attributes could impact the overall outcome of the weighted overlay.
