Model exactly where water goes — coastal, riverine, glacial-lake outburst — over terrain accurate to half a metre.
Credible flood and hazard planning is a terrain problem: the answer to “what floods if water reaches this height” depends on elevation accuracy that public 30 m DEMs do not have, producing risk maps with error bands too wide to act on.
SkySpera runs inundation and discharge modelling over a globally-validated 1 m BaseDEM at 0.5–1 m vertical accuracy, rendered over Refined Reality 1 m imagery. Flood Simulation answers the height-to-footprint question anywhere; GLOF Early Warning models the water actually released by a breaching glacial lake and where it would travel.
The same terrain engine extends to dam-breach scenarios and post-fire debris cascades — one consistent worldwide elevation foundation under every water-and-hazard question.
