Suitability modeling framework

Available with Spatial Analyst license.

The Suitability Modeler is a dynamic, interactive environment of panes, plots, and maps that you can use to create a suitability model. For an overview of the framework, the issues it addresses, how it does so, and the dynamic nature of the framework, see What is the Suitability Modeler.

A series of panes guide you through the suitability modeling process. A Suitability Modeler pane with the following tabs appears when you open the modeler:

  • Settings—This tab is used to define the overall model settings. You can specify the name of the suitability model, the range of the suitability scale, and whether to weight the criteria by a multiplier or percent.
  • Suitability—This tab is where you identify the individual criteria and weight them relative to one another to create the suitability map. Queries can be specified to explore the model input and output. The Transformation pane works in conjunction with the Suitability tab, allowing you to transform the criteria values to the common suitability scale.
  • Locate—This tab is used to identify the final locations from the suitability map created in the Suitability tab that best meet the subject's spatial requirements. Spatial requirements include the total area and number of regions, their minimum and maximum sizes, and the ideal distances between the regions.

The Transformation pane appears when you click the button next to a criterion in the Suitability tab of the Suitability Modeler pane. Use the Transformation pane and its plots when you are determining the best transformation method to apply to each criterion.
