User requirements for water quality remote sensing products and means of meeting them

* Corresponding author. ** The work was co-financed by TEKES and the Academy of Finland Abstract – 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 related remote sensing techniques and information systems: Information on properties of land areas influencing the observed water body was one of the main parameters requested. The potential of target area based monitoring system ULAPPA in meeting the user requirements was investigated. ULAPPA is designed to integrate remote sensing and other information on pre-specified areas of interest.
