The challenge
The disaster management team was relying on manual effort that could not keep up with volume, and every miss had a direct cost.
What we built
We owned the whole stack — hardware, firmware, models and dashboards — using PyTorch, GDAL, PostGIS so there was one accountable team.
Delivery timeline
Phase 1
Discovery sprint and site survey
Phase 2
Prototype built and tested in the Motera lab
Phase 3
Pilot on site with before/after measurement
Phase 4
Scale-out, training and handover
Highlights
- Integrated with existing PLC, ERP or GIS systems — no rip-and-replace
- Before-and-after measurements agreed with the client up front
- Runs on-premises; no data leaves the site unless agreed
- Documentation, drawings and source handed over at close
