Introducing the BlueDot Water Observatory

Thanks to the wet winter season 2018 in Western Cape the prospects for Day Zero in Cape Town in 2019 are very low. The water levels of the Theewaterskloof Dam acquired through the BlueDot web application.

Who can Benefit from the Water Observatory and How?

In 2016, Marocco was hit by the worst drought in three decades. Their second-largest dam, Al Massira, shrunk by more than 60 percent over the last three years. Left: Time-lapse created in EO Browser includes the images from 2015 to 2018. Right: The data from BlueDot application are clearly showing slow rise of the water levels since January 2018.

Technology Used

The shape files of water areas from OpenStreetMap are visualized in blue. The BlueDot Water Observatory application provides the shape files of the current state of the water body based on cover classification, which are visualized in orange. Image shows the Folsom Lake, U.S. on November 6, 2018.
