Water Environment Data Modules

Water body health is an important social issue concerned by governments at all levels and the public. However, due to the extensive distribution of water systems and numerous pollution sources, conventional monitoring methods often rely on ground sensors and focus on “points”, which cannot achieve global monitoring. As a supplement to conventional monitoring method, satellite remote sensing can analyze time-series variation of water pollusion on a macro level, and locate polluted lake and river rapidly, achieving the new monitoring mode: “View from the sky, search on the internet, look on the ground.”

TerraQuanta collects abundant satellites resources to routinely monitor water bodies such as rivers, lakes, and ponds at large-scale and high-frequency, providing a distribution diagram of water quality parameters for all water bodies in certain area, which clearly reflects the water quality distribution trend and its dynamic changing situations. This will provide necessary evidences for preventing and controlling the occurrence and development of water pollution, as well as aiding users in making decisions with scientific data in water environment monitoring and protection.
