More on Zone Sets
A zone set comprises one or more zones based on geography; all the geographic areas in a single zone compose an accumulation area. You create zone sets to enable Touchstone to accumulate exposures in zones that you select during a Detailed Loss Analysis.
The Compatibility field indicates whether the zone sets you are creating are compatible for Detailed Loss analyses (Touchstone), for Aggregate analyses (Touchstone Re), or for both types of analyses. The green indicator tells you that the zone set is compatible for the specified type of analysis while the gray indicator tells you that the zone set is not compatible. Both indicators are gray by default when you launch Zone Set Manager. There are various cases where the Aggregate indicator is dimmed. The indicator will be green as long as you have selected areas with resolutions that are supported for Detailed Loss or Aggregate loss. For example, when you select North America > United States, the indicators remain green because the United States area contains supported resolutions for both types of loss. If you then, for the same zone, select North America > Alaska Offshore, both indicators remain gray because the zone contains unsupported resolutions for Alaska Offshore. The Aggregate indicator will also be dimmed in other cases, such as when aggregate losses are not supported for a particular region or country, such as for Africa.
If the zone set includes resolutions, such as "Country", supported in both products, the indicator will be green for both products. For detailed information about Touchstone Re options, refer to the Touchstone Re Help.
You can create zones with geographic areas up to Postal-level resolution.
You can create zones manually by selecting each geographic area to include in the zone set. However, you can also add a lot of zones much more quickly by using the Bulk Select option, which enables you to view loss results with greater granularity.
Touchstone retrieves label information for the geographic regions from the tGeolabel table in the AIRGeography database.
The default number of zones that you can view in the Zones panel is 1,000. However, administrators can configure the maximum number of zones that are displayed in the panel. When the number of zones exceeds that limit, the panel is 'frozen'. While the zones have been created, you cannot edit the zone set. You can, however, save the zone set that you created. Even if you cannot see zones in the Zones panel, you can select them when configuring a Detailed Loss Analysis.
