Utilizing Remote Sensing and Digital Elevation Models to Estimate Historic Wetlands.

Accounting for wetland loss after European settlement is diffucult due to the dreastic changes in land and water managememt. This research explores utilizing terrain attributes derived from a digital elevation model, legacy data from soil survey and present day remote sensing. The results from this study demonstrated that a decision tree based on high topographic wetness indices, poor and very poor drainage classes and NDVI could be used to construct pre-European wetland extent for portions of the glaciated midwest.
