BHARAT 3D: 3D Land Administration Architecture for India
3D ULPIN Mapping System — From 2D Parcels to Vertical Property Research · Engineering · 3D Cadastre From a 2D Parcel to a 3D Property Our journey towards building a 3D ULPIN Mapping System for representing vertical, underground and elevated property. We started with a simple question: What happens when land is no longer just a flat piece of land? A conventional cadastral map is fundamentally two-dimensional. But modern cities are not. Apartments occupy different floors. Parking can exist below ground. Metro lines can pass beneath properties. Roads can pass below buildings. Tunnels, pipelines and elevated structures can occupy the same geographic location at different heights. This made us realize that the problem was not simply about drawing buildings in 3D. The real problem was understanding how a property identity could be ...
