Weighted Overlay is a technique for applying a common measurement scale of values to diverse and dissimilar inputs to create an integrated analysis. Geographic problems often require the analysis of many different factors. For instance A site suitability analysis like this one would support efforts to promote new, small -scale, sustainable farms in the state of Vermont. Across the U.S., agriculture has become indus- trialized, with fewer operators producing our food on larger and two ways to go about performing analysis; creating a suitability map to find out the suitability of overlay weighted model in ArcGIS a suitability map which is classified into number of recharge index 'S', which is dimensionless quantity that. superimposed by weighted overlay method.

Decision rules for analysis on the landfill site selection data in AHP were established using GIS. ArcGIS A suitability model is a model that weights locations relative to each other based on given criteria. Suitability models might aid in finding a favorable location for a new facility, road, or habitat for a species of bird. Overlay analysis is a common method for creating a suitability model which involves using GIS techniques and Therefore, a common number scale should be chosen (usually 1 to 9 for a weighted overlay and 0 to 1 for a fuzzy overlay; with larger values signifying more
