BLUEDOT — Water Resources Monitoring from Space

Developing countries in particular need affordable, yet reliable solutions and tools for monitoring available water resources.Introducing the BlueDot Water ObservatoryThe BlueDot Water Observatory service is based on the Copernicus satellite imagery that provides timely information about water levels of lakes, dams, reservoirs, wetlands and similar water bodies globally..The water levels of the Theewaterskloof Dam acquired through the BlueDot web application.The goal of the BlueDot is to monitor the water levels of over ten thousand water bodies in near real time across the planet..Our solution builds on top and is complementary to previous projects like Global Surface Water Explorer (by the European Commission’s Joint Research Centre and Google) and demonstrates the possibility of building an efficient global EO service, freely available and practically fitting into your laptop.Who can Benefit from the Water Observatory and How?The BlueDot Water Observatory provides a valuable service to local authorities, governmental agencies, natural parks and reserves, agricultural ministries and agencies, stakeholders in food production, and citizens alike..They can use the data provided by the Water Monitor through the RESTful API as an important input in their decision-making process, planning, or simply to display water levels of water resources of their interest on-line.Although the BlueDot provides useful information and easy-to-use services on its own, it can also serve as a starting point, a reference, around which a larger, predictive analytics-oriented business focused on exploitation of satellite imagery can be built.In 2016, Marocco was hit by the worst drought in three decades..Right: The data from BlueDot application are clearly showing slow rise of the water levels since January 2018.Technology UsedThe BlueDot Water Observatory is based on the following key technologies and data sources:Satellite imagery is acquired using sentinelhub Python package, which uses Sentinel Hub services.Cloud masking is performed using s2cloudless Python package developed by Sinergise.The list of monitored water bodies is based on GWSP’s Global Reservoir and Dam (GRanDv1.01) database, and WWF’s Global Lakes and Wetlands Database (levels 1 and 2)..We believe that the BlueDot Water Observatory will take an important role in providing a relevant data base of water bodies combined with the full archive of satellite imagery up to date.Find more information about the BlueDot project on the official page and freely explore all currently available data through the Dashboard..
