Overview of Creating a New Geospatial Analysis

You open a project and select or highlight the exposure view on which you want to run a Geospatial Analysis. You can also open the contract on which you want to run the analysis. You can create a single exposure view that contains both property and workers' compensation exposures and run a Geospatial analysis against that view: this is called a combined exposure view. You cannot run a Contract Geospatial Analysis against a combined exposure view.

Under Run Analysis, you select Geospatial. The New Geospatial Analysis pane lists the selected exposure view or contract in the Analysis Target field and the default template in the Template field.

At any time during the process, you can select additional targets in the Analysis Target list. You can select any existing template that is available within your business unit to run your analysis. Templates streamline the configuration process for analyses that you run frequently. You can create a new template or save changes to an existing template at any time during the configuration process.

Geospatial Analysis includes a map, with map tools in a vertical column to the right of the map. The map enables you to visualize what you are configuring before you run the analysis. For example, you can visualize:

  • Events and hazard layers, along with associated exposures, to see whether there is any overlap.

  • Where Touchstone will place rings, for the top number of risks by total replacement value (TRV), AIR landmarks, or user-supplied addresses.

  • Multiple analysis targets, one at a time, by clicking (the eye icon) next to the target in the target list. You can do this only for targets for which exposure summaries were generated; the eye icon does not appear next to the target if an exposure summary was not generated. To run an analysis on targets for which no exposure summary was generated, you select the check box next to each target.

There are three clearly marked workflow steps in Geospatial Analysis. After you select an analysis type (Step 1 - Choose Analysis Type), Geospatial Analysis offers you options appropriate to that analysis type. For example, when you select Ring Accumulation as the analysis type, the configuration options appropriate for a ring analysis appear in the Step 2 - Configure pane. In addition, options in Step 3 - Modify Settings and Reinsurance vary according to your choices in Steps 1 and 2. The following list provides a link to each workflow step:

The bottom of the New Geospatial Analysis pane includes an area where you name the analysis, specify the Result database, and run the analysis.
