In ArcGIS Pro's Suitability Modeler, the output layers are automatically updated whenever a transformation or weight is applied or changed, provided that the Auto Calculate option is checked on the Suitability ribbon. This is the default behavior. However, this automatic updating may not be desired in all cases. For example, if you are assigning the suitability values for each land use type, you may not want the maps to update with each assignment but instead wait until you assign all the suitability values for all the land use types.  To manually control when the updating is to take place, uncheck Auto Calculate., When unchecked the following occurs: the graph in the Transformation Pane will update when any parameter is changed, the Suitability map and the transformed raster layer will not update, which'll speed up things while you are exploring parameters, weights can also be changed without the maps being recalculated and redrawn.   Unchecking Auto Calculate, allows you to quickly refine your criteria without waiting for the maps to refresh after each adjustment. Once you are satisfied with your changes, simply click the Calculate button   on the ribbon to apply the changes and all the affected maps and graphs will also update. ... View more

I have criteria which are already transformed to a common scale, how can I use them in Suitability Modeler to create a suitability map and find the most suitable locations? We can use the Submodels input type and treat the transformed criteria as submodels and in so doing avoid the transformation step. On the Settings tab of the Suitability Modeler, change the Model input type from Criteria to Submodels Then on the Suitability tab, add the transformed criteria.   A suitability map is automatically created after each transformed criterion (or submodel), is added. Then click the Run button to convert the raster function suitability map to a persisted raster dataset. Then use the Locate tab to identify the best locations from the suitability map that was created by the transformed criteria. ... View more

When using the Suitability Modeler in ArcGIS Pro, the criteria must be transformed onto a common scale, and this is done on the Transformation Pane. These transformed criteria are combined to create the suitability map. Unless explicitly set, all these layers are processed as raster functions,  which processes raster data in real-time without creating a new file on disk. Instead of writing a new permanent raster, functions are applied "on the fly" as you view the data, which is faster and saves storage space.  However, if you want to use the transformed rasters outside the Suitability Modeler application, you should check the Save transformed dataset when model is run option. This "save" will take place when the Run button on the Suitability tab is clicked. This "Run" operation will also convert the suitability raster function to a raster dataset.       ... View more
