Redacted counties. Real geometry.
Operational clients don't want their response gaps published — so names, coordinates, and case numbers are redacted. What stays is the part that matters: the geometry, the method, and the numbers the work produced.
Re-positioning a SAR team on slope, not road.
A rural county's SAR response sectors were drawn from the road network — asphalt-distance — because road data is clean and terrain data isn't. We pulled 18 months of incident logs and re-ran every staged response against terrain-distance: slope, surface by season, snow and ice windows. About 14% of calls had a closer unit that was never dispatched.
The rebuild took a weekend. Across the first eleven incidents on the new sectoring, mean recovery time dropped 28% — a real number from a small sample, published with that caveat attached.
- Revised sector maps — gridded by terrain-distance, with seasonal overlays
- A one-page decision rule for IC — laminated, lives on the wall
- A terrain-weighted assignment layer for CAD, refreshed quarterly and during named risk windows
Case files publish when redaction allows.
Every engagement produces a written deliverable; not every deliverable can be published. When one can, it lands here and in Field Notes — geometry intact, identities removed.
