Terra Cover launches ReaLSAT as new surface water monitoring service

Terra Cover announces the release of a new surface water monitoring service, ReaLSAT (Reservoir and Lake Surface Area Timeseries), for freshwater analysis and research. The ReaLSAT service provides global surface area monitoring for water bodies with sizes greater than 0.01 square kilometers.

The insights derived from robust tracking of these water bodies enables customers in insurance, water resource management, and infrastructure development industries to incorporate the impact of changes in freshwater availability in business operations. 

In a recent case study, Terra Cover analyzed 1329 reservoirs (built for hydropower or irrigation) in Uruguay. In 2018, which witnessed one of the worst regional droughts in history, total surface area decreased by almost 40 % across the country. According to Terra Cover analysis, current 2020 figures also show alarming reductions in surface areas.

As part of its commitment to providing best-in-class capabilities for public understanding of critical freshwater resources, Terra Cover now manages an open-source dataset, ReaLSAT, that provides surface area variations for 669005 freshwater bodies around the world, including over 18000 reservoirs, at a monthly scale from 1984 to 2015.

Freshwater researchers can use the dataset with monthly records to determine long term trends and predict future conditions. The dataset is available for download at https://terracover.ai/realsat/.
