This is a compilation of ARC/Info coverages and grids from various sources, and of varying accuracies, which have been cropped to the Sedgwick study area.  These can be used for all kinds of terrain analysis or graphical presentation of spatially referenced data using Arc/Info, ArcView, Idrisi, or any other software that will accept ARC-formatted data.

• Datasets:  geology, watersheds, aerial photos, digital elevation model, slope grid, aspect grid, etc
• Errors in digital elevation models, how they propagate, and ways to deal with it (important for any analyses run on any DEM derivative grids)
• Animation showing Monte Carlo simulations of DEM error over the Sedgwick area
• Format of downloadable files and data projection information
• Examples of how these datasets can be used
