From flood to freeze: mapping natural perils for insurance/ conveyancing
Track: Insurance
Authors: Jill Boulton

As financial regulations have changed insurers are required to understand the risks they are underwriting at a much more granular level than ever before. For residential/commercial properties one of the key descriptors is location. Also as insurance prices/underwrites to property level, home buyers need to understand what they are buying and the impact that will have on future insurance costs and property value. The complexity of natural perils modelling for flooding, freeze and wind means ArcGIS. Is a natural choice to build the models on a national scale but at 5m resolution to enable the property level delivery of results. JBA have pioneered new methodologies to model all these perils and deliver the complex multi- layer results as a simple index insurers can use in their pricing and underwriting engines.
