<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>🗺️ &#039;&#039;&#039;Geographic information system (GIS)&#039;&#039;&#039; is a technology platform that captures, stores, analyzes, and visualizes spatial data — and in the insurance industry, it has become an indispensable tool for evaluating location-dependent risks such as [[Definition:Natural catastrophe | natural catastrophe]] exposure, [[Definition:Flood insurance | flood]] zones, wildfire proximity, crime density, and distance to fire protection. Insurers have long understood that geography is one of the most powerful predictors of loss, and GIS transforms raw geographic data into actionable intelligence that feeds [[Definition:Underwriting | underwriting]], [[Definition:Rate-making | pricing]], [[Definition:Claims management | claims]] response, and [[Definition:Portfolio management | portfolio management]] decisions.<br /> <br /> ⚙️ In practice, GIS platforms overlay multiple data layers — property parcel boundaries, elevation models, historical weather patterns, soil liquefaction maps, coastal surge zones, and more — to produce a richly detailed picture of risk at any given location. An [[Definition:Underwriting | underwriter]] evaluating a commercial property submission can use GIS to assess its exposure to [[Definition:Hurricane | hurricane]] wind speeds, proximity to a fault line, or position within a [[Definition:Flood zone | FEMA flood zone]], all within seconds. [[Definition:Catastrophe modeling | Catastrophe modelers]] rely heavily on GIS to geocode insured locations and feed them into simulation engines from vendors like AIR, RMS, and CoreLogic. On the [[Definition:Insurance claim | claims]] side, carriers deploy GIS during large-scale [[Definition:Catastrophe | catastrophe]] events to triage affected policyholders, route adjusters efficiently, and estimate [[Definition:Incurred but not reported (IBNR) | IBNR]] exposure by mapping damage footprints against their in-force book.<br /> <br /> 📍 The strategic value of GIS extends into [[Definition:Portfolio management | portfolio accumulation management]], where [[Definition:Reinsurance | reinsurers]] and primary carriers monitor the geographic concentration of their exposures to avoid excessive aggregation in high-risk corridors. With climate change altering historical risk patterns — shifting wildfire perimeters, expanding flood plains, and intensifying convective storm zones — GIS-driven [[Definition:Geospatial analytics | geospatial analytics]] have moved from a nice-to-have to a core competency. [[Definition:Insurtech | Insurtechs]] are pushing the frontier further by integrating real-time satellite imagery, drone-captured data, and [[Definition:Internet of Things (IoT) | IoT]] sensor feeds into GIS workflows, enabling near-real-time risk monitoring that was unimaginable a decade ago. Carriers that invest in mature GIS capabilities gain a measurable edge in [[Definition:Risk selection | risk selection]] accuracy and speed to market.<br /> <br /> &#039;&#039;&#039;Related concepts&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Geospatial analytics]]<br /> * [[Definition:Catastrophe modeling]]<br /> * [[Definition:Flood insurance]]<br /> * [[Definition:Underwriting]]<br /> * [[Definition:Natural catastrophe]]<br /> * [[Definition:Risk assessment]]<br /> {{Div col end}}</div>
