MAPPING OF WATER QUALITY DYNAMICS DERIVED FROM HYPERSPECTRAL EO DATA FOR THE TAM GIANG LAGOON IN CENTRAL VIETNAM

Abstract:

The primary objective is to analyse the temporal evolution of water quality in the Tam Giang, Lagoon using hyperspectral Earth Observation (EO) data and to design advanced geovisualization outcomes of these data. The aspects addressed are (1) the analysis of water quality parameters over time and (2) the visualization and cartographic representation of the derived results. The research employs advanced hyperspectral EO sensors to assess critical water quality indicators. The student will also use Copernicus data. The lagoon is studied to understand some of the dynamic behaviour of the ecosystem; for that, a temporal analysis is used to discern patterns and dynamics in water quality parameters. The study will assess variations in water quality indicators over time, shedding light on the lagoon's environmental changes and temporal dynamics. Innovative geospatial mapping visualization techniques will effectively illustrate these findings, clearly understanding the spatial distribution of water quality within the Tam Giang Lagoon. The outcome of the thesis will present the analysis and advanced geovisualization of the Lagoon water quality dynamics based on a series of rasters.
