Tactical Urban Vector Surveillance

Offline-first mosquito tracking. 100m discretized risk intelligence.

Engineered for cellular dead-zones in Mirpur-2, Dhaka. Powered by SQLite transactional queues, FMTC raster tile caching, and hazard-evasive shortest path routing.

Core Innovations

Engineered for real-world field defense

Storage Protocol

Zero-Loss 4-Phase Sync

Anchor metadata before binary media payloads. Uses client-side UUIDs for strict idempotency and preserves verified status flags via safe field merging.

Spatial Math

100m Discretized Lattice

Snaps GPS reports using floor bounds into 0.0009° lattice cells. Applies a conservative highest-wins severity model so single high-risk pools are never masked.

Pedestrian Safety

Hazard-Aware Routing

Evaluates an 8-connected grid using weighted soft penalties (Low: 1.0, Medium: 100.0, High: 1000.0) with diagonal normalization to steer pedestrians away from vectors.
