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.〔Wade, T. and Sommer, S. eds. A to Z GIS〕 Overlay analysis is a common method for creating a suitability model which involves using GIS techniques and software.〔“Understanding overlay analysis”. Esri. http://resources.arcgis.com/en/help/main/10.2/index.html#//009z000000rs000000〕 Overlay techniques were originally advanced by Ian McHarg who used a manual overlay cartographic process which he describes in his 1969 book Design with Nature.〔Malczewski, J. 2004. “GIS-based land-use suitability analysis: a critical overview”. Progress in Planning, 62(1), 3-65. http://ced.berkeley.edu/courses/fa11/ldarch254/www11/readings/Malczewski_2004.pdf〕 With the advancement of computer mapping software, suitability modeling has become much easier and faster to implement, and today it is used for many varying tasks.〔 == Overview == There are seven general steps required to create an acceptable suitability model: # Define the problem # Break the problem into submodels # Determine significant layers # Reclassify or transform the data within a layer # Weight the input layers # Add or combine the layers # Analyze 〔〔Mitchell, A. 2012.
