FloodMap.net website

FloodMap.net is a well-known web-based simulation tool launched to visualize the potential impacts of global sea-level rise and flooding. The platform's origins are closely tied to the work of British software developer Alex Tingle, who originally created a similar "mashup" tool known as Firetree.net in 2006. This tool used Google Maps combined with NASA's Shuttle Radar Topography Mission (SRTM) data to show how different levels of sea-level rise could submerge coastal areas worldwide.

Over time, FloodMap.net emerged as a dedicated portal for this technology, expanding on the original concept by offering more precise elevation analysis and high-resolution modeling. While the site is often cited by international organizations like the UN-SPIDER for disaster risk management, it remains an independent project rather than a government-owned service.

Today, the platform is operated as a global digital service, with its development and administrative oversight rooted in the United Kingdom. It provides both free educational features and a premium "FloodMap Pro" subscription service for users requiring professional-grade elevation data and ad-free simulations.
