A weighted raster overlay service helps you identify locations based on your criteria and answer geographic questions. You can build these services from your vector and raster data using tools from the ArcGIS platform. Your portal can host these services, and your planners, stakeholders and others can use them in GeoPlanner for suitability modeling. This allows you to share your data and analysis tools with specific groups, organizations, or the public.
This document introduces the concepts you'll need to understand to set up your own weighted overlay service.
Hosted weighted overlay services are built from mosaic datasets that are shared as image services. This functionality uses various ArcGIS platform tools and components. You'll need the following components to set up your own weighted overlay service:
- ArcGIS Image Server 10.6
- ArcGIS Desktop
- Portal for ArcGIS
There are three general workflows you'll need to follow to configure and share your own weighted overlay service. The Weighted Raster Overlay Service toolbox contains analysis tools that will help you prepare and configure your data for a weighted overlay service. Use of these tools is recommended as they will apply the proper fields, properties, and metadata to your rasters and mosaic datasets.
Prepare your data
Add data to a mosaic dataset
Publish your data as a weighted overlay service
To make your mosaic dataset available as a weighted overlay service, you have to share it as an image service to an ArcGIS Image Server site. This step includes adding a tag, weightedOverlayService, when you share the item to your portal so that GeoPlanner can identify it as a weighted overlay service.
