MnModel Digital Terrain Model (Pits Removed), Minnesota

This dataset was developed for use in Mn/Model4 archaeological predictive model. NOTE: The compressed dataset is over 4 GB in size due to the high resolution scale and statewide extent of the data.<br/> <br/>The DTM10COND raster feature dataset that was generated from existing statewide LiDAR elevation data, and processed to remove man-made features such as roads and ditches, to the greatest extent possible. Bathymetric data were used to replace level lake places for large lakes with existing bathymetric survey data. Topographic data from 1899, digitized by Minnesota Geological Survey were used to replace a portion of the Mesabi Iron Range, restoring the pit mine lands to a more natural surface. DTM10CONDPR is a pit-removed version of the DTM10COND, that was processed with the TauDEM (Terrain Analysis Using Digital Elevation Models) Pit Removal Tool to fill-in all sinks so that state wide surface hydrology calculations could be performed using other TauDEM Tools. TauDEM is a collection of surface hydrology processing tools available from Utah State University, created by David Tarboton.
