The method behind both products
Siltation and Emission Monitoring run on the same discipline: satellite observation, checked against an area's own history, held to a pattern before it's trusted, and delivered with its uncertainty attached. This page is about the technology.
Six steps, repeated continuously.
Pass
New satellite imagery, on its own schedule, for your Area of Interest.
Extract
Measured per area of interest.
Compare
Checked against that area's own history.
Gate
Bad-weather days excluded.
Deliver
Severity flags, plain-language summary.
What has to hold before a reading counts
Validated on real data first
Checked at small scope before it scales.
Compared to its own history
Measured against its own normal.
Physics doesn't transfer automatically
Each site earns its own thresholds.
Persistence before a flag
One reading is weather, not a trend.
Every figure carries its uncertainty
Published error bands, not false precision.
Geometry is checked by eye
Verified visually, never generated blind.
What we're building
Satellite-derived bathymetry
Direct depth from imagery. Needs clearer water.
AI-modelled bathymetry
Depth inferred from historic surveys and modelling.
What it doesn't do.
Not a live feed
Repeated observation over days, held across passes — not an hourly alarm.
Not a certainty claim
Every figure carries a published error band. No number is presented as more precise than it is.
Not an audit certification
An independent baseline any subsequent audit can start from — not a substitute for one.
Not an accusation
An observation about conditions, not a claim about who is responsible for them.
