For this lab we were examining and area and performing a suitability analysis. We utilized both vector and raster analysis tools. We began with the Boolean method which break the area into "yes" and "no" areas for suitability. Next, we used a method of scoring and weighting. With this method you don't have a simple yes and no but rather a range from least to most suitable depending on the criteria met. Weighting also allows rank the criteria in the order of what is most important. For example, near a water source is more important than being near a road and so forth.
The scenario we were given was to conduct an analysis for a property developer for areas best suited for development bases on Land cover, Soils, Slopes, Streams and Roads.
The side-by-side layout below illustrates how different the results are when you use an alternate weighted scenario versus an equal weighted scenario.
