One of the things that Protei may be able to do is to transport physical oceanographic equipment such as sonar.
I regularly collaborate with the Grassroots mapping group that is now becoming officially formed as the Public Laboratory.
In this video tutorial co-edited with Adam Griffith of the University of Western Caroina, we demonstrate how to extract a specific color from a UV picture and quantify how much area of wetland there is on this image.
1. isolate the part that you are interested in using the menu/ image/ adjustment/ replace color. There you want to have a quite fuzzy selection and darken the desired part.
We may be able to use such simple technique with Protei when transporting scientific observation equipment.
