Insurance companies can underwrite millions of locations and having too much risk in one place can mean the difference between profit and loss. In this session we will explore the business challenge and understand how a geospatial platform based on Elasticsearch and the Uber H3 spatial index can help insurers make better decisions. Insurance companies can underwrite millions of locations through complex distribution networks of brokers and direct channels and having too much risk in one place can mean the difference between profit and loss, In extreme cases a catastrophic event such as 9/11 could bring down the company completely. In this session we will explore the business challenge and understand how a geospatial platform based on Elasticsearch and the Uber H3 spatial index can help insurers make better decisions and avoid accumulation issues. The techniques that we will demonstrate are applicable to many real-world problems where we have large amounts of data that need to be visualised and analysed in real-time.
