Satellite Site Monitoring

See what’s changing
on your sites.

Amelia Space Technologies turns satellite imagery, ground sensors, and third-party data into continuous monitoring and automated alerts. Reservoirs, catchments, coastlines, landholdings: if it is a fixed place where change matters, Amelia watches it and tells you what to do about it.

The platform

This is what your team sees each morning.

No dashboards to build, no imagery to interpret. The Amelia Planetary Intelligence Platform watches your site and gives you one clear read. For a source-water reservoir, that read is a bloom nowcast: is a bloom forming, and do you need to send someone to sample?

Watch

Conditions favour a bloom. The satellite signal is elevated and above the sample-now line, but no bloom is confirmed yet.

Recommended

Pull an in-situ sample this week and review carbon dosing.

Taste & odour (geosmin) risk

Chance your next weekly grab sample crosses the taste threshold.

Elevated

An early signal, not a lab result. Amelia tells you which reservoir to sample and when, days before the numbers come back. Only an in-situ sample confirms or rules out a bloom. Illustrative preview.

An early signal, not raw data

A bloom reading with a plain-English verdict and a recommended action. No imagery to interpret, no dashboard to build.

Know which site to sample first

Amelia covers every site you give it and ranks where the risk is, so a small team is always sent to the one that needs them.

Ahead of the problem, not behind it

A satellite catches a bloom forming before a grab sample comes back from the lab, and before your customers ever taste it.

How it works

From satellite signal to decision.

01

Detect

Amelia ingests every satellite pass over your site and flags what changed since the last look.

02

Understand

AI models plus human-in-the-loop review classify the change and filter false alarms, so an alert means something.

03

Predict

Risk scoring combines current signals with historical patterns and weather to flag a problem before it is visible.

04

Act

You get the alert and a recommended action, in plain language. Analysis that took months takes minutes.

What goes in, what comes out

What goes in

  • Radar, in any weather

    Synthetic aperture radar sees through cloud, smoke, and darkness. Sentinel-1 provides a continuous baseline; commercial radar is tasked when a site needs finer detail or a faster revisit.

  • Optical, across the spectrum

    Multispectral imagery that reveals what the eye cannot. Sentinel-2 covers most sites at 10 m every 2 to 3 days, with commercial sub-metre optical brought in when a question needs it.

  • Decades of history

    The Landsat record reaches back to the 1980s. Every site starts with a baseline of what normal looks like, so change means something.

  • Specialist sensors

    Thermal, hyperspectral, and atmospheric instruments, commercial and public, selected for the question rather than the other way round.

  • Ground and in-situ sensors

    Your lab and field readings, fused with the view from orbit to anchor and sharpen it.

  • Third-party and regulatory data

    Weather, terrain, land registry, and compliance datasets, layered onto the same map.

What comes out

  • What changed, and whether it matters

    Every pass compared against the last, with the noise filtered out, so an alert means something happened.

  • A risk read in plain language

    A 0 to 10 signal with a verdict and a recommended action. For a source-water reservoir today, that read is a bloom nowcast.

  • Automated alerts

    Email or API the moment a site crosses a threshold, with a recommended action attached.

  • Where to look first

    Risk scores and priority ranking across every site, so a small team can hold a large territory.

  • The evidence behind it

    Full-area maps, time-series, and the satellite scene each call was made from.

Running today

Amelia’s bloom detection runs in production on the UK’s largest lake as part of a government-funded remediation programme, and for a US water utility that came to Amelia directly. Same pipeline, two continents, two very different questions.

Read the case study

Change does not wait for your next site visit.

Sites are inspected on a schedule. They change on their own. By the time someone walks the ground, or a sample comes back from the lab, the thing you needed to catch has already moved. Continuous monitoring gives you those days back.

Bring your site to Amelia

What you can watch

For the sites too big, too remote, or too important to guess about.

Site monitoring is a capability, not a single use case. The satellites, the change detection, and the alerting stay the same. What changes is the question you ask of them. Amelia is honest about where that question already has an answer.

Proven today

Water quality and algal blooms

Early warning for source water: harmful algal blooms, taste-and-odour (geosmin), turbidity, and contamination risk across whole reservoirs. This is where Amelia has the deepest proof.

Catchments and land use upstream

A continuous watch over the ground that feeds a supply, from nutrient-loading pressure to land-use change miles from the water itself.

Environmental compliance

Evidence-grade monitoring of discharge, land use, and change over time, mapped to the checks regulators ask for.

Same pipeline, proof still being built

Satellite change-detection map showing cropland change across a region

Land and vegetation change

Clearance, growth, disturbance, and biomass across large or remote landholdings, from a baseline that reaches back decades.

Satellite flood-intelligence map showing inundation extent

Water extent and flood

Mapping where water is and where it has moved, during and after an event, using radar that works through cloud.

Satellite maritime-monitoring view identifying vessels inside a restricted marine zone

Maritime and ports

Activity and emissions around ports and protected waters, developed as part of an ESA consortium (in progress).

If it is a fixed place on Earth where change matters, bring it to Amelia. We will show you what a satellite already knows about it.

Common questions

How do companies monitor sites with satellites?
Satellites pass over the same location repeatedly, capturing optical and radar imagery each time. Software compares each new pass against the last to detect change, then turns that change into alerts, risk scores, and reports. Amelia Space Technologies combines radar and optical imagery from public constellations such as Sentinel-1, Sentinel-2, and Landsat with commercial high-resolution and specialist sensors, ground readings, and third-party data, so a site is watched continuously rather than inspected occasionally.
Does satellite monitoring replace water sampling?
No. Amelia gives you an early satellite signal of where and when a bloom is forming, days before lab results, so you point your sampling team at the reservoir that needs them. Only an in-situ sample confirms or rules out a bloom. The satellite makes your sampling faster and better targeted; it does not replace it.
What can satellite site monitoring detect?
Anything that changes the surface or the signal it reflects and scatters: algal blooms and water quality, taste-and-odour (geosmin) risk, flooding, land-use and vegetation change, clearance and disturbance, and surface change over time. The right sensor depends on the target, which is why Amelia fuses several satellite sources instead of relying on one.
Can Amelia monitor sites other than water?
Yes. Site monitoring is a capability rather than a single use case: the sensors, the change detection, and the alerting are the same whatever the site is. What changes is the question asked of them. Amelia has the deepest proof in water, where bloom detection runs in production for drinking-water protection, and applies the same pipeline to land and vegetation change, water extent and flood, and activity around ports and protected waters. If a site is a fixed place on Earth where change matters, it can be watched.
How often is a site updated from satellite?
At mid-latitudes, radar imagery is typically available 4 to 5 times a week and optical imagery every 2 to 3 days in clear conditions. Combined, most sites receive new observations almost daily. Where ground sensors are connected, the picture updates continuously.
Can you monitor a site through cloud cover or at night?
Yes. Optical satellites cannot see through cloud, but Synthetic Aperture Radar (SAR), such as Sentinel-1, uses microwave signals that penetrate cloud, smoke, and darkness. Amelia ingests both, so monitoring continues regardless of weather or daylight.
Can you monitor reservoirs for taste and odour (geosmin)?
Yes. Alongside the bloom signal, Amelia forecasts taste-and-odour risk, the chance that your next grab sample crosses the geosmin taste threshold, so water utilities can adjust carbon dosing and get ahead of customer complaints rather than reacting to them.
What data sources does Amelia use for site monitoring?
Amelia is sensor-agnostic by design. Public constellations provide a continuous, economical baseline: Sentinel-1 radar, Sentinel-2 multispectral optical, and the Landsat archive for long-term history. On top of that, Amelia tasks commercial high-resolution optical and radar, and specialist thermal, hyperspectral, or atmospheric sensors, where a question needs them. Ground and in-situ readings and third-party datasets such as weather, terrain, and regulatory records are fused into the same view. The sensor is chosen for the question, not the other way round.
How is this different from buying satellite imagery?
Raw imagery is a picture. You still need specialists, time, and tooling to turn it into a decision. Amelia delivers the decision: a bloom nowcast, automated alerts, risk scores, and a recommended action through its Planetary Intelligence Platform. Analysis that used to take months takes minutes, and your whole team can use it, not only GIS specialists.
