How does remote sensing determine water quality?

Remote sensing provides water quality data with a high spatial and temporal resolution for thousands of lakes at a time. It supports the evaluation of environmental problems and potential health risks through the analysis of changes in water quality and the detection of harmful algal blooms.

What are the water quality measurement indicators?

Chlorophyll, total nitrogen TN, total phosphorus TP, transparency, COD, turbidity, ammonia nitrogen NH3-N, suspended matter concentration.

How does hyperspectral remote sensing work?

Hyperspectral remote sensing involves breaking a broadband from the visible and infra-red into hundreds of spectral parts, which allows a very precise match of ground characteristics, such as color, to the reference standards.
