Sentinel 2 and Landsat 8 help monitor water quality from space!

The coastal habitats including the near shore water and land bodies are essential for the sustainable development of the economy and play an important role to the societal growth. Decision makers, urban planners, and environmental organisations are using Geographic Information Systems (GIS) along with satellite images and ground through data to help them understand and better manage the local ecosystem.


Landsat 8 and Sentinel 2 have the capability to map and monitor the water quality (Chlorophyll concentration, sea surface temperature, water transparency, total suspended matter, etc) of vast region of interest within a timely response. Calibrating these data with ground trough measurements results to a complete system that can actually provide positive impact the environment and the economy.


By using differentmulti-temporal spectral indices, such as NDVI, the user can determine which water quality parameter is abnormal or affects naturally protected areas.

I'm a Remote Sensing and a Surveying Engineer. I received my degree from NTUA in 2010, where I also received my Ph.D. in hyperspectral remote sensing in 2016. From graduation in 2010, my career started as a Researcher Associate and Teaching Associate in the Laboratory of Remote Sensing of NTUA. From that time I also worked at several private companies as a Remote Sensing Expert and Geospatial Analyst. From the beginning of 2015 I was positioned as Senior Earth Observation Expert. During these years, I have participated in more than 20 funded European Commission and European Space Agency projects, have over 16 peer reviewed scientific publications in the field of Remote Sensing, and have an international patent in hyperspectral data compression.My main research and professional interests are in the optical remote sensing area, where I specialize in data (images, point measurements) processing and algorithm design and development. Some of the software tools that I operate to accomplish my research and business dreams are SNAP, ENVI, IDL, QGIS, ERDAS Imagine, ArcGIS, and Python. I have been working with these tools since 2008.
