MEASUREMENTS AND HYPERSPECTRAL ANALYSIS FOR WATER QUALITY
Objectives
- Conducting in-situ water quality analysis using sensors mounted on a USV and transmitting the data via Internet of Things (IoT) platform
- Water sampling using USV and performing contaminants analysis in the laboratory
- Hyperspectral / Multispectral imaging and analysis of water bodies for mapping of water contaminants
- Performing correlation and regression analysis between in-situ and spectral data, and development of spatial distribution maps of pollutants
