Using 3D Mapping Technology to Predict and Protect Against Flood Risks

The video discusses the severe floods in Shrewsbury in 2000 and the subsequent challenges faced by homeowners. A British insurance company is now using advanced 3D mapping technology to predict flood risks for individual properties, rather than entire neighborhoods. This involves creating virtual floods to assess potential impacts. Data is collected using airborne radar and aerial photography to create a digital elevation model, which is combined with software to predict flood occurrences and spread. The project, welcomed by Shrewsbury's local government, will expand across the UK. With climate change potentially doubling flood frequency in 50 years, accurate data is crucial for property protection.
