– Monitoring of environment requires several sources of information to be combined: "General knowledge" of the monitored area, measurement information on it and naturally previously made assessments of the same area. To use earth observation in monitoring of for example lake water quality, traditional images have limited value: How could they be used for(More)
– A user survey was conducted among Finnish professional users on their requirements on water quality information, which could be produced with remote sensing. The purpose of the survey was to direct the related research and development to the most interesting applications from the user perspective. The results additionally highlight the requirements for(More)
– Two field campaigns were used to demonstrate the usefulness of an atmospheric correction method specifically developed for Case 2 waters. The correction method utilizes bio-optical reflectance modeling and principal component analysis. The MODTRAN radiative transfer code simulations were conducted to obtain a statistical database for varying atmospheric(More)
