Impact of terrain analysis components on the land use classes
Project Leader: Dr. Mohamed Hegazy (L) and Mr. Hesham El-Askary, GMU
Background:
Terrain Analysis employs elevation data to generate 2-D and 3-D perspective views, slope or aspect maps, stereo images, and shaded relief maps, and determines watersheds, drainage basins, and volumes under surfaces. Results from Terrain Analysis may be used as input with other GIS layers for Land Use classification or modeling. Terrain analysis for Virginia terrain can be helpful relating: ecological and environmental analyses, land planning and management, natural resource management, and site analysis and evaluation.Technical Approach
Our goal is to use a digital topographic map for Virginia in order to generate and run the terrain analysis components on it. The result is expected to be a classification of Virginia terrain based on its slope and aspect and the impact these parameters have on the land use characteristics of different classes as a function of crop productivity.A slope map is generated to classify the county areas into different classes based on the slope of the terrain. Different areas of different slope surface can be chosen for different land use purposes. An aspect map is generated to classify the county areas based on its slope directions. Areas facing different directions can be chosen or neglected for different land use purposes.
