Kari Kallio defended earlier today his thesis on remote sensing in boreal lakes at the university of Helsinki. I wasn’t there, but I took a glimpse at his thesis. Very interesting developments in technical apparatus, indeed. In a country like Finland with thousands of lakes it sure would be handy to be able to get results of many, many lakes without much effort. But. We are not there yet. A lot of algorithms still need to be calibrated. And algae counted. 🙂
