SPHERESPHERE is an open, auditable framework for structure-level natural hazard risk analysis across tsunami, flood, hurricane, and more.Structure-Level Hazard Risk, Backed by Open MethodsSPHERE is Niyam's open, auditable framework for high-fidelity natural hazard risk analysis at the structure level. Tsunami, flood, hurricane, and beyond, quantified with transparent methods that hold up in peer review, grant applications, and budget meetings.Client ResultRecognized by Federal Partners and the Resilience CommunitySPHERE has been demonstrated to FEMA leadership and presented across the emergency management, geospatial, and academic communities as a viable, open, auditable alternative for high-fidelity hazard risk analysis.

FEMA: Tsunami module demonstrated directly to FEMA leadership.

AGU: Talk accepted at the American Geophysical Union, confirming the underlying scientific rigor.

National Reach: Featured at NSGIC, FLHUG (Florida HAZUS User Group), and Climate Week NYC.

What SPHERE ProvidesSPHERE empowers decision-makers with actionable intelligence for mitigation, planning, and response. By leveraging open data and transparent methodologies, it delivers structure-level hazard risk analysis that any team can review, audit, and extend. No black boxes, no proprietary lock-in.Multi-Hazard CoverageOne Framework, Many ThreatsSPHERE is built to expand. Each hazard module shares the same transparent methodology and structure-level resolution.

Tsunami (icon: FaWater): Demonstrated to FEMA leadership, extending multi-hazard reach beyond legacy tooling.

Flood (icon: FaCloudShowersHeavy): Integrates FEMA's National Flood Hazard Layer and the National Structure Inventory for fast, structure-level loss estimates with full data provenance.

Hurricane (icon: FaWind): Pairs high-resolution weather data with proven Hazus loss methodology for precise, point-level wind risk.

Why It WorksSPHERE replaces census-tract approximations with building-by-building insight. Its open, auditable foundation supports peer review and extensibility, so agencies can integrate new datasets, add new hazard types, or contribute back without fighting a vendor. And because every result is traceable from input through output, SPHERE analyses hold up to stakeholder scrutiny in mitigation plans, grant applications, and capital decisions.Outcomes

Defensible Results (icon: FaShieldAlt): Transparent methods that stand up to scrutiny, ideal for grant applications and capital planning.

Targeted Investment (icon: FaTachometerAlt): See where mitigation dollars buy the most risk reduction.

Repeatable Analysis (icon: FaSyncAlt): Standardized assessment teams can rerun as data, hazards, and policy evolve.
