Every Instagram Photo Becomes Raw Material for 3D World Maps

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.
