ANALYSIS OF THE REMOTELY SENSED WATER QUALITY PARAMETERS OF THE INSUBRIC LAKES: METHODS AND RESULTS OF THE INTERREG SIMILE PROJECT
Download as PPTX, PDF0 likes53 views
The SIMILE project focuses on integrating monitoring of the Insubric lakes and their ecosystems to enhance cross-border governance and water quality management. It employs various methods, including remote sensing and citizen science, to analyze water quality parameters and promote environmental awareness. The project encompasses a comprehensive data analysis spanning from January 2019 to November 2022, using multiple satellite datasets and monitoring strategies.
