The shift from curated image databases to billions of casually uploaded photos across social platforms collapses the cost and latency of building photorealistic 3D models of physical spaces. Modern structure-from-motion algorithms extract spatial geometry from overlapping images without metadata, turning Instagram's archive into an inadvertent surveying infrastructure. Real estate, urban planning, and navigation systems now access frequently-updated, crowd-sourced 3D models that outpace traditional satellite imagery. The trade-off: people's social media feeds become raw material for commercial mapping products, raising questions about consent and privacy that existing frameworks don't address.
