IPPUC calls it the same mapping technology NASA and the US military use. What's verifiable is plainer: a live 47-layer cadastral map and a laser-scanned 3D model that measures shadows on buildings the public still can't edit.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

IPPUC's GeoCuritiba platform, launched in March 2022, replaced static maps with a live cadastral GIS: a 47-layer parcel, zoning and boundary database plus Curitiba 3D, a photorealistic model built from aerial and laser survey data that simulates shadows and measures building height, street width and façade area for planners and engineers.
🎓 Lesson
Access is tiered — full editing stays inside IPPUC's own technical team and a restricted layer, while the public-facing version is a viewer onto curated map galleries, not an open, editable dataset.
