Monitoring the quality of both marine and large inland water bodies is essential for many reasons. Considering the ever-growing pressure that water resources are being subjected to from human activities, having timely information on the status of water resources at a large scale is hugely useful in a number of fields. Earth Observation-derived data can be a cost-effective and efficient complement to other monitoring methods (such as in situ surveys) and even substitute these methods where they become too expensive or logistically impractical (remote locations) to carry out. The large spatial coverage of EO-based monitoring methods is one the clearest advantages of this source of data.
Star2Earth uses a variety of satellites and sensors to carry out monitoring of water quality. This will vary depending on the size of the area to be monitored/studied, the spatial resolution, the frequency needed and the parameter to be monitored.
The parameters offered by Star2Earth for water quality monitoring derived from EO-data are the following:
- Surface Temperature
- Total Suspended Matter
- Transparency (Secchi depth)
Starlab has participated in a number of large research projects related to water quality monitoring, such as the following:
- MyOcean1 and MyOcean2
- Vulnerability maps
- Statistical studies of water quality parameters
- Historical evolution studies
- Medium and high resolution monitoring services
