BASIN fills the gaps; it does not replace.
Field sampling, automatic stations and satellite bloom maps each do something well. BASIN fills the gap between them: the wide area and the days ahead.
At a glance
What is different?
| Field sampling | Automatic stations | Satellite bloom status maps | BASIN | |
|---|---|---|---|---|
| Coverage | Sampled points | Installed points | Whole water body | Whole water body (10 m cells) |
| Frequency | Scheduled days | Continuous (point) | Satellite pass days | ~5 days (concentration), daily (drivers, alerts) |
| Cloud & night | Not affected | Not affected | Gaps under cloud | Radar keeps watching water |
| Days-ahead forecast | None | None | Usually none | 3–7-day alerts, 7/14/30-day grid forecasts |
| Spread path & intake arrival | None | None | Usually none | D+1 to D+7 spread map, arrival date |
| Explains the cause | Measured items | Measured items | Usually none | Five-driver status table |
| Accuracy check | Reference data | Reference data | Up to the user | Automatic validation table |
| Field equipment | People and boats | Installation needed | None | None |
A summary of typical characteristics; specific organisations and products may differ. Field sampling and stations remain the reference data used to validate BASIN.
Differences
Not a status map, but grounds for action.
Radar, optical, weather and field data
Radar sees water through cloud and at night, optical reads concentration, and public measurements correct satellite proxies.
Two stages, both directions
From satellite candidates to field checks, and from station or CCTV anomalies to satellite and upstream context.
Explainable alerts
Temperature, N, P, sunlight and residence time for each water body show the reasons behind each alert.
Grid-level forecasts
Forecasts for each 100–500 m cell, not the lake average, show which intake side rises first.
Self-validating
Error and alert recall against measurements are calculated automatically on screen.
Low cost
A proven shared satellite engine and free public satellites keep costs almost flat as you add water bodies.
FAQ
Frequently asked questions
If we have stations, do we need BASIN?
Stations give precise values at their points. BASIN shows the wide area between them and the days ahead. They work best together.
How is it different from other satellite bloom maps?
Satellite bloom maps usually show where water is green today. BASIN adds the five drivers, alerts days ahead, spread paths and automatic validation against measurements.
Can it reduce field sampling?
It helps choose where to sample first, so sampling and patrols go where they are needed. Sampling for official decisions is still required.
Work with us
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.
