About Authority · 3D Bhu-Aadhaar
The Authority is a specialized 3D Cadastral & Vertical Property Authority engineered by Team AeroNerds for the Smart India Hackathon 2026 (SIH26011), in alignment with the Department of Land Resources (DoLR), Ministry of Rural Development. The platform pioneers 3D Bhu-Aadhaar and assigns discrete 3D spatial identifiers (3D ULPIN) to multi-storey buildings, vertical property units, and subterranean infrastructure across India. Height signals are derived from satellite DSM and DEM and never presented as an exact floor count without field verification. Statutory aspects such as legal title, tax dues, and encumbrance are formally declared not determinable (NOT_DETERMINABLE).

Cadastral Khasra & Bare-Earth DEM Terrain Fusion Specification v1.8
Automated FSI/FAR municipal violation detection across 6 pilot cities
Across the gated pilot regions of Bhopal and Bengaluru, exactly 6,163 buildings carry the full evidence-fusion output: 2,326 PASS, 3,652 CORRECT, and 185 FLAG. The remaining four regions (Indore, Navi Mumbai, Kalyan-Dombivli, and Coimbatore) represent earlier-stage pilots where raw building geometries and cadastral parcels are indexed prior to supervised AI gating. Height signals are derived from satellite DSM and DEM and never presented as an exact floor count without field verification. Statutory aspects such as legal title, tax dues, and encumbrance are formally declared not determinable (NOT_DETERMINABLE).

Have Questions?
View All FAQ →How does 3D Bhu-Aadhaar assign an identity to a multi-storey flat?
It fuses 2D Khasra parcels, Copernicus bare-earth DEM ground datum, and building footprint heights to calculate vertical floor boundaries and assign a hierarchical 3D ULPIN.
What is the difference between bare-earth DEM and surface DSM?
Bare-earth DEM captures ground elevation above Mean Sea Level (MSL), whereas DSM includes rooftop heights and vegetation canopy, allowing precise slab extraction.
How are FSI/FAR violations flagged for town planners?
The automated compliance scanner evaluates total constructed floor area against permitted municipal plot coverage and zone ceilings in real time.
Can a citizen dispute a vertical parcel boundary?
Yes. Citizens can lodge an official grievance directly to the Sub-Divisional Magistrate (SDM) desk with supporting sanction plans and mutation proofs.
