Continuous basin surveillance
Weekly multispectral satellite sweeps flag anomalies across entire river stretches, not just lease boundaries, so unauthorized activity is detected at the source.
Move from Gate Monitoring to Source Monitoring.
Detect, verify, and prove illegal riverbed sand extraction at basin scale using a layered workflow: weekly satellite alerts -> 0.5 m verification -> drone volumetrics -> LiDAR forensic audits.

A basin watchdog for enforcement, revenue protection, and scientific replenishment
Traditional approaches focus on transport gates and weighbridges. This framework adds basin-wide source monitoring to detect extraction at the river itself, then escalates only the highest-probability targets to expensive ground assets.
Rapid verification and volumetrics
0.5 m satellite imagery confirms flagged sites; drone photogrammetry computes extracted volume and compares it against permitted limits to quantify violations.
Evidence-ready enforcement
cm-level LiDAR audits provide tamper-proof, courtroom-grade depth proof. Every alert is traceable end-to-end: satellite -> drone -> LiDAR -> penalty.
The operational gap
Cameras see the road, not the river. Illegal excavation often happens outside lease areas, hidden by bends, vegetation, or temporary access roads. Without source monitoring, enforcement becomes reactive and disputable.
- Unauthorized extraction outside lease boundary
- Unreported volumes and royalty leakage
- Rapid riverbank damage and habitat loss
- Weak linkage between permits and on-ground extraction
The funnel methodology focuses expensive assets only after satellite confirmation.
How it works: a 4-level escalation workflow
A cost-efficient method that moves from wide coverage to courtroom-grade proof.
Level 1 - Alert layer
Regional surveillance (weekly)
Satellite indices flag "green / minor variance / high-probability anomaly" zones and detect new access tracks and turbidity.
Level 2 - Slider check
High-resolution verification (0.5 m)
Confirm suspected excavation and stockpiles with targeted high-res imagery before deploying field assets.
Level 3 - Volumetrics
Drone photogrammetry
Compute extracted volume and compare with permitted limits to quantify violations.
Level 4 - Forensic evidence
LiDAR audit
Centimeter-level "bare earth" models provide tamper-proof depth proof, even through vegetation, for legal enforcement.

Statewide command center
Full API link with i4MS, statewide dashboard, automated compliance reporting, and continuous replenishment monitoring.
FAQ
Does this replace existing checkpost / i4MS systems?⌄
No. It complements them by adding source monitoring and linking extraction evidence to the permit and transport chain.
How do you keep operational costs under control?⌄
The funnel approach uses basin-wide satellite screening first and escalates only high-probability targets to high-res imagery, drones, and LiDAR.
What data do you need from us to start a pilot?⌄
Lease KML/KMZ files, a sample DSR/SoI sheet, district boundaries, and any historical drone or survey data you already have.
Is the evidence admissible in court?⌄
Yes. The evidence pack includes a chain-of-custody trail, signed orthophotos, LiDAR depth models, and timestamped satellite reports.
