3edata offers data capture and processing services on water bodies in order to generate cartographic products such as thematic maps of surface water quality.
We are mainly focused on monitoring the most recurrent problems in inland water bodies that compromise the quality of the resource, and which have to do with accelerated eutrophication processes triggered by an excess of nutrients in the water, leading to the systematic appearance of algal blooms (in some cases of toxic algae that endanger human health (cyanobacteria)) as well as anoxia processes and high turbidity. All these processes are expected to become more frequent in future climate change scenarios, as there will be an increase in water temperature and a greater recurrence of storm events with floods that increase turbidity episodically and introduce nutrients into the system. In this context, it is necessary to obtain data with a higher temporal and spatial resolution that allows reservoir managers and water supply companies to act in an early and precise manner.
The methodology applied by 3edata integrates information from satellites (Sentinel 2), multispectral images captured from RPAS devices and on-site data.
