Siren Coverage Modeling
Field-validated coverage estimates for outdoor warning systems
A FEMA CPG-1-17–anchored planning tool that models real-world siren audibility across terrain, foliage, and wind effects.
Outdoor Warning System Planning
A FEMA CPG-1-17–anchored planning tool that models real-world siren audibility across terrain, foliage, and wind effects.
Line-of-sight shadowing from Copernicus elevation data, with diffraction-aware onset so valleys behind ridges read correctly.
FEMA distance-doubling & frequency correction baseline with an ISO 9613-2 atmospheric correction — calibrated against field-experience, not idealized models.
Branded coverage studies, 3D terrain views, and multi-siren reinforcement modeling.
