Geospatial Analysis

Geospatial Analysis enables you to perform a deterministic risk analysis with your own view of risk on accumulations of property exposures and workers' compensation information in given areas exposed to natural and man-made catastrophes. It combines powerful spatial visualization with exposure, hazard, and loss data, providing you with important insights into the risks to your exposures. You can get a quick geographic view of where your property exposures are accumulated, and you can drill down to key locations to understand the surrounding areas. In addition, you can run a geospatial analysis on property exposures in regions, and for perils, which have no catastrophe models.

Touchstone enables you to import and add offshore exposure information for accumulation purposes. Although Touchstone does not model these offshore regions, you can include these regions in geospatial analyses.

You can also perform a Geospatial Analysis on accumulations of workers' compensation information, enabling you to view, by ring, the total number of insured employees and the total number of day shift, evening shift, and night shift employees.

While you can run an analysis on exposure views that contain both property exposures and workers' compensation information, you must run the analysis separately for each type of exposure. If you select "Property Exposure" as the exposure type and the exposure view contains workers' compensation data, the system filters out the workers' compensation data during the analysis. If you select "Worker's Compensation" as the exposure type and the exposure view contains property exposures, the system filters out the property exposures during the analysis.

Geospatial Analysis requires a license. If you do not license it, it does not appear in the product. Click here for more information about licensing considerations.

Geospatial Analysis enables you to accumulate global property exposures by risk-based values (replacement, number of locations, number of risk, and location limits and deductibles) and by exposed limits (ground up, gross, net of pre-CAT, post-CAT net). It uses the Touchstone Financial Module to evaluate the impact of contract terms, limits, and deductibles along multiple dimensions of exposure characteristics, hazard information, historical event parameters, and modeled loss results. This supports better underwriting decisions, for example when you want to analyze how underwriting new property exposures contributes to existing exposed limits.

Since Geospatial Analysis results are deterministic, you should view them by one accumulator at a time. AIR recommends that you run a Geospatial Analysis with one accumulator (zone, ring, event, or boundary) at a time. If you run the analysis with multiple accumulators, AIR recommends that you view the results through the Accumulation Display rather than through the Interactive Browser. However, if you want to run an analysis with multiple accumulators and you want to view the results through the Interactive Browser, make sure that you include the accumulator name as either a row, column, or filter when you create an advanced widget to view the results. If you do not include the accumulator name, the widget display may make it appear that the values are being double counted because of locations that fall in more than one accumulator.

You run a Geospatial Analysis on an exposure view, which becomes the analysis target.
