Comparison Of Terrain Indices And Landform Classification Procedures In Low-Relief Agricultural Fields, Derek A. Evans, Karl W. J. Williard, Jon E. Schoonover Jan 2016

Comparison Of Terrain Indices And Landform Classification Procedures In Low-Relief Agricultural Fields, Derek A. Evans, Karl W. J. Williard, Jon E. Schoonover

Journal of Geospatial Applications in Natural Resources

Landforms control the spatial distribution of numerous factors associated with agronomy and water quality. Although curvature and slope are the fundamental surface derivatives used in landform classification procedures, methodologies for landform classifications have been performed with other terrain indices including the topographic position index (TPI) and the convergence index (CI). The objectives of this study are to compare plan curvature, the convergence index, profile curvature, and the topographic position index at various scales to determine which better identifies the spatial variability of soil phosphorus (P) within three low relief agricultural fields in central Illinois and to compare how two methods …


Electric Current: Siting A Wind Farm Off The Coast Of Maine, Ryan S. Clemens Jan 2016

Electric Current: Siting A Wind Farm Off The Coast Of Maine, Ryan S. Clemens

Atlas of Maine

Using ArcMap, I analyzed several operational factors that would lead to a successful wind farm off the coast of Maine. Through calculating Euclidean distances and reclassifying the distances to fit within a 10-point scoring system, much of the coastline is viable for a potential wind farm. However, the most suitable area is a 115 square mile location 8 miles off the coast of Lincoln and Cumberland counties.
