CRESTA zones provide a universal standard for the exchange of aggregated, insurance-related information among insurers and reinsurers. This year a comprehensive reform goes into effect that will expand the previous 43,000 zones to more than 250,000 zones and extend to a total of 137 countries worldwide. GfK GeoMarketing is the official supplier of the digital CRESTA zone maps.
In order to provide insurers with a more unified, up-to-date and streamlined reporting standard, the CRESTA organization no longer defines CRESTA zones based on perils and disaster incidences. The zones are now based on official postcode and administrative maps from GfK GeoMarketing, the largest provider of digital maps of postal and administrative boundaries on the market. As of May 2013, the new CRESTA zones were subdivided into high-resolution ("HighRes") and low-resolution ("LowRes") zones. The high-resolution zones are ideally suited to data exchange and natural catastrophe modeling, while the low-resolution zones are intended for accumulation control and data visualization. Zones were previously available for 86 countries, along with supplementary subzones. The CRESTA database has been expanded to include 137 countries and can be accessed freely by users from the insurance and reinsurance industries at www.cresta.org. This service is sponsored by Munich Re and Swiss Re. "Postcodes and administrative zones offer greater detail and a more clearly defined data basis," says Dr. Jürgen Schimetschek, head of the CRESTA secretariat and risk manager at Munich Re. "This is an important prerequisite for accurate, up-to-date risk analyses." "The highly detailed 2013 CRESTA maps are a direct response to the demand for precise and reliable maps and data sources by reinsurance companies," explains Simon Luehr, coordinator for map projects at GfK GeoMarketing. Worldwide demand for a precise cartographic basis for estimating risk and damages from natural catastrophes continues to grow. The new CRESTA maps offer users from across the entire insurance and reinsurance industries a valuable basis for calculating insurance policies. CRESTA.org – online database for the reinsurance industry CRESTA additionally offers assignment tables (so-called "mapping tables") for correlating the old and new zones. Users can also visualize aggregated insured sums per CRESTA zone by uploading a standardized ACORD (Association for Cooperative Operations Research and Development) table. One useful new feature lets users quickly and easily determine the CRESTA zone for any entered coordinates. Applications in GIS applications and other mapping solutions Digital maps serve as the foundation for the geographic analysis of data in specialized mapping software. The branch-specific CRESTA maps support reinsurers in estimating regional damages and risks from natural catastrophes such as storms, floods and earthquakes. GfK GeoMarketing offers worldwide digital maps illustrating postcodes and administrative regions such as municipalities. GfK GeoMarketing’s regularly updated and expanded maps comprise the largest collection of digital administrative and postcode maps on the market. GfK GeoMarketing has established a reputation in the industry for global coverage, attention to detail and precisely rendered boundaries that fit together without gaps and overlaps. GfK GeoMarketing also provides regionalized market data that fits seamlessly with their maps, such as detailed, Europe-wide data on purchasing power, inhabitants and households. This geodata makes it possible to estimate potential damages and claims on a regional basis.
