This allows multiple cells from different raster layers to be weighted and summed into a suitability score. Weighted overlay requires that input data ranges be mapped to an output common suitability scale. This information enables the service to display the criteria inherent in each raster layer for overlay and analysis. Define raster layer field data using the Configure Raster Fields toolĮach raster layer within the weighted overlay service's mosaic dataset must present certain information. This tool adds raster layers to a new mosaic dataset, populates fields specific to a weighted overlay service with information created by the Configure Raster Fields tool, and sets a key property value in the mosaic.īoth Configure Raster Fields and Build Mosaic Dataset are part of the Weighted Raster Overlay Service toolbox. It also details how to create a new mosaic and add your raster layers to it using the Build Mosaic Dataset tool. This document describes how to create that additional information using the Configure Raster Fields tool. Each raster layer added to a weighted overlay service must have this additional information. This includes a raster layer title, input value ranges, mapping to an output suitability scale, and range labels for display within the weighted overlay service. The additional information is used to describe raster layers within a weighted overlay service. Once you have prepared your data and generated a set of geoTIFF rasters, create some additional information about those rasters before adding them to a new mosaic dataset. Make sure you follow the instructions in that document before you continue with the workflow outlined below. See Prepare your data for information on how to create and configure your raster datasets for inclusion in a weighted overlay service. The mosaic dataset must contain specific fields, information, and properties to enable overlay based on location and criteria. The weighted overlay service allows you to overlay the raster layers within that mosaic to identify areas based on your criteria.
