Suitability modeling is one of the most common applications for a GIS analyst. It can be used to determine the best location to build a shopping center, housing development, or ski resort. You can also use it to find the best areas for parks, endangered wildlife habitat, or flood control. Suitability modeling is one of the first applications you are taught when learning GIS. It is the application that made you fall in love with GIS.
Traditionally, creating a suitability model is a linear process. You needed to understand the steps in the workflow in which you independently specify the parameters for each criterion with little knowledge of their effect on the output. You had to trust the process when creating the output.
The newSuitability Modeleris an interactive, exploratory environment for creating and evaluating a suitability model. It is available now for ArcGIS Pro 2.6 with a Spatial Analyst extension license.
The basic premise underlying the Suitability Modeler is that a model is a dynamic process. Constructing a suitability model is a nonlinear, iterative process. At each step of the workflow, analytical feedback is provided through interacting maps, plots, and panes. This allows you to make informed decisions on the parameters you specify and easily see how they will affect the final output.
The Modeler allows seamless back and forth movement between each stage of the model development. What you learn in one stage of the process may influence the decisions you make in another.
Because of the exploratory and interactive nature of the Suitability Modeler, you can justify each step of your modeling process. As a result, you will be more confident in the model output leading to better decisions.
The best way to understand the Suitability Modeler is to see it in action. The following video was presented at the Plenary of the 2020 Esri User Conference.
The content of the blog The new Suitability Modeler: Changing the way suitability models are created is written by Kevin Johnston. Kevin has been a Product Engineer on the Spatial Analyst development team for over 29 years. He has degrees in Landscape Architect from Harvard and in environmental modeling from Yale. At Esri, Kevin’s current focus is developing suitability and connectivity tools. He hopes the tools that he works on can help users make more informed decisions.
Sarmistha is a Senior Product Engineer in the raster analysis group at Esri, and works on raster and scientific multidimensional data analysis. Her primary interest is in the application of GIS for environmental and climate change modeling to study changes for conservation and improved decision making. When not making maps, Sarmistha likes to experiment with her cooking skills!
