Creating a New Geospatial Analysis

You run a Geospatial Analysis 5.0 on an analysis target, which can be a single exposure view or contract. Refer to the Geospatial Analysis 5.1 Help for information about creating the analyses in Touchstone 5.1.

AIR recommends that you always review your exposure data by opening the exposure view before you configure and run an analysis. The Exposure Summary Dashboard provides a visual overview of your exposure data.

Process overview

To perform a Geospatial Analysis:

1.     Create a project or open an existing project.

2.     In the Project Data pane, select Exposure Views, and then highlight the exposure view for which you want to configure and run an analysis.

3.     In the New Analysis area of the navigation pane, click Geospatial. The New Geospatial Analysis pane displays the name of the analysis target and indicates how much of the exposure data has not been geocoded. If the percent of non-geocoded data is high, you may want to fix the data before running the analysis.

4.     Optionally, select a Geospatial Analysis Template in the Templates field to pre-configure the analysis.

5.     Under Analyze Exposure Type, select Property Exposure or Workers' Compensation, depending on whether you want to analyze property exposures, or accumulate workers' compensation information in rings. When you select Workers' Compensation, the only available options are to accumulate values by Rings and to enable dynamic results.

6.     For a Property Exposure analysis, specify the values you want to analyze: Exposure Attributes and/or Exposed Limits.

7.     Specify what to accumulate the values, by: Zones, Rings, Custom Boundaries, AIR Event Footprints, Custom Event Footprints, or Hazard Boundaries. For a Workers' Compensation analysis, you can select only one method of accumulation: Rings.

8.     Optionally, for a Property Exposure analysis, select the spatial outputs you want to include: Static Hazard, Custom Hazard, Detailed Loss Results, and Additional Attributes.

9.     Optionally, for a Property Exposure analysis, select Settings & Save By, which, by default, accumulates analysis results by contract, layers, and locations. Currently, you cannot change the Save By setting. You can turn Disaggregation on or off (the default); if you leave the default setting, there is no automatic disaggregation for any countries (this is different for loss analyses). You can also apply location terms for residential contracts (using the AIR Default Behavior or by applying deductibles before limits).

10.  Optionally, for a Property Exposure analysis, apply reinsurance programs.

11.  Optionally, select the Enable Dynamic Results check box if you want to try"what if" scenarios" in many different ways. When you select a spatial output (for a Property Exposure analysis), Geospatial Analysis automatically selects this option and you cannot clear it.

12.  Click Analysis Management to configure analysis-specific functions.

13.  In the Analysis Name field, leave the default name, which includes the exposure view name and the type of analysis, or enter a unique, alphanumeric identifier.

14.  Click Run. Touchstone adds the project to the Activity Monitor queue for processing when the required system resources are available.

15.  View the analysis results.
