A product that measures its own accuracy.
BASIN automatically compares its results with monitoring-station measurements (chlorophyll, total nitrogen, total phosphorus, temperature) and reports error, correlation, alert recall and F1 for each water body.
Why it matters
Accuracy in numbers, not claims.
To use satellite analysis in daily operations, you need to know how right it is. Each time new measurements reach the public monitoring network, BASIN compares them with its results and recalculates accuracy. The same table supports audits and certification.
- Compared with chlorophyll-a, total nitrogen, total phosphorus and temperature
- Metrics: error, correlation, alert recall, F1
- Validation table per water body (CSV download)
- Measurements also correct satellite proxies
Pilot targets
Numbers to confirm in an official pilot.
Current performance comes from our own pilot water bodies. In a pilot we plan to verify these targets officially.

FAQ
Frequently asked questions
What measurements are used?
Chlorophyll-a, total nitrogen, total phosphorus and water temperature from the public monitoring network. In a pilot we also use the operator’s sampling data, water levels and releases.
Can I get the validation results?
Yes. A validation table with error, correlation, recall and F1 per water body can be downloaded as CSV.
How accurate is it today?
Today’s figures come from our own pilot water bodies, so we do not publish them as official numbers. We will share them after verifying the targets above in an official pilot.

Start with a satellite screening of your water.
We screen your reservoirs and intakes from public satellite data first, then compare the results with your own field measurements. No equipment needs to be installed.
