What changed in the city, and who signed off.
Planning and permits with a record that does not get rewritten. GovScope proposes, a planner signs off, and old parcel sheets land on the same map through automatic registration.

Real
Every layer is public satellite data over a public suburb. Green loss, new structures and the cluster are computed by a script in this site's repository.
Illustrative
The city on this page is a public example, not the client. The permit check is the action GovScope would propose, not a result from that city.
What runs here.
Each product below works on government and municipal today. Atlas is the engine they share.
GovScope
Permits and planning for a large Canadian city: planner sign-off on every AI result, a kill switch, and a full audit trail.
Sheet registration
Scanned parcel maps placed on the satellite frame automatically, and refused when the fit is poor.
Atlas
The engine under every product: fusion, registration, detection, and an agent on the map.

What it has shown.
Numbers from real runs, each with the caveat it needs. Nothing here is a claim the run did not make.
- 6.15 m
trusted leave-one-out error, scanned sheet to satellite, 8 control points
Internal measurement on one golden run. The in-sample figure is lower and never quoted.
- ~5 min

A cold job takes about 75 minutes on one GPU.

Beyond that it stops and asks.
How it works.
Open any part for the method, the numbers and where to read more.
The scanned sheets become a parcel graph: text masked out, ink skeletonised, junctions found. The satellite side becomes a road graph. A dense matcher searches zoom levels for a coarse fit, and the fit is scored by leave-one-out error, never in-sample.
A seed that fails the gate is refused, and a recovery search over cluster shapes takes over. The pipeline fails closed.
Every file is still checked against the by-law, but by a planner reading a pre-checked file with the gaps already marked, instead of finding them weeks later.

Why it matters.
Public figures on the size of the problem.
Municipal permit volumes range from under 500 a year in a small town to more than 3,000 in a large city, and every file is checked against the by-law by hand.
