wq_calc

Calculates a set of water quality indices

The main purpose of waterquality is to quickly and easily convert
satellite-based reflectance imagery into one or many well-known water quality
algorithms designed for the detection of harmful algal blooms or the following
pigment proxies: chlorophyll-a, blue-green algae (phycocyanin), and turbidity.
