A data quality analysis is the most effective way to assess and enhance your portfolio-level catastrophe exposure data. The Touchstone® data quality diagnostics enable you to determine the strengths and weaknesses of the exposure data you are using for portfolio-level catastrophe modeling and even supplement that data when it is missing or weak. These diagnostics are fully customizable, enabling you to approach exposure data enhancement based on your individual underwriting strategy and business needs. Through rich graphics and maps, they provide high-quality and flexible capabilities for producing reports about exposure data for internal and external audiences.

Touchstone data quality analyses provide the following diagnostics:

• Validation and Scoring: Validation and scoring enable you to evaluate and quantify the completeness and reasonability of property location data, primary and secondary risk characteristics, and replacement values within a portfolio.
• Benchmarking: Benchmarking enables you to compare your exposure data to industry data based on lines of business, construction types, and occupancy types. This diagnostic also enables you to view or export industry exposure data.
• Augmentation: Through configurable rules, augmentation adds property-specific building information to your portfolio when this data is missing or when confidence in the data is low. You can augment building location, property value, and primary and secondary risk characteristics by using trusted data from AIR’s property-specific database, or you can update data using user-specified values.
