Vangrid's smartphone network for 3D spatial data collection

One post describes Vangrid as a smartphone network for real-world 3D captures, with provenance anchored on-chain. Another cites 1.25M-plus captures, 450K-plus users, 4,700-plus attestations and $600K-plus USDC settled. A third argues that the tougher challenge may be keeping spatial data current as physical environments change.
