MnModel Topographic Wetness Index, Minnesota

This dataset was developed for use in Mn/Model4 archaeological predictive model. NOTE: The compressed dataset is near 1 GB in size due to the high resolution scale and statewide extent of the data.<br/> <br/>The Topographic Wetness Index (TWI) raster feature dataset was calculated using TauDEM (Terrain Analysis Using Digital Elevation Models) software. TauDEM is a collection of surface hydrology processing tools available from Utah State University, created by David Tarboton, version 5 of the software can be accessed here: http://hydrology.usu.edu/taudem/taudem5/index.html<br/><br/>

dsPurpose The purpose of this dataset is to provide a MnModel with a raster dataset that can be used to help assess the potential for wetlands or hydric type soils statewide and to serve as input to the MnModel Phase 4 archaeological predictive model. The information herein was used for predicting the potential for finding unknown archaeological sites early in the transportation construction planning process, so that impacts on these sites can be avoided.

This dataset is best suited for general reference only. It is not suitable for precise land measurements or ground surveys.
