Weighted Overlay Analysis in Arc GIS
In this video, an agricultural suitability analysis is performed via the most commonly applied GIS software Arc GIS using a test site in Ethiopia.
Multi-criteria weighted-overlay analysis is the process of allocating areas on the basis of a variety of attributes that the selected areas should possess. Slope, aspect, soil type, rainfall amount, vegetation condition, climate, river proximity, road proximity, borehole proximity, settlement proximity, and many more constraints might apply based on the type of suitability conditions.
Although this is a common GIS operation, it is best performed in the raster space using a grid-based approach.
