Land Use as it Relates to Land Slope
Description
The goal of this project is to analyze the relationship between the slope of land and agricultural land use. The output was analyzed to determine a threshold point at which agriculture practices drop off in relation to higher slope values. Slope of the land is important to agricultural practices because it impacts drainage and net crop primary production. Agricultural land was extracted from the 2001 National Land Cover Dataset using reclassification tools in ArcGIS 9.3. The slope of the contiguous United States was derived from the United States Geological Survey National Elevation Dataset by using the slope tool in the spatial analyst toolbox. Agricultural land was multiplied by the slope in order to determine the amount of agriculture for each degree of slope. The results of this project will be used to help guide future land use models.
