Suitability Analysis revisited
A little while ago I posted the old handwritten Suitability Analysis notes from when Steve Strom used these techniques in his studio. This four page set of Suitability Analysis notes is online now as a PDF (broken link fixed). His description of weighted analysis lacks a graphic, so I created a digital version of both some of his graphics and a new Weight and Rate graphic that should help you work through it all as you look ahead to Monday's exam:To be clear, each grid shows the very same piece of land but being rated for a different issue (soils, slope, vegetation). Presumably that is fairly objective. But each individual criterion is then weighted based on relative importance. In this case, Slope has rather subjectively been weighted as 5 times more important that Vegetation. If you click on my graphic it will enlarge and be more readable.
