The Database for Hydrological Time Series of Inland Waters (DAHITI) was developed by the Deutsches Geodätisches Forschungsinstitut der Technischen Universität München (DGFI-TUM) in 2013 to provide water level time series of inland waters. Today, DAHITI provides a variety of hydrologial information on lakes, reservoirs, rivers, and wetlands derived from satellite data, i.e. from multi-mission satellite altimetry and optical remote sensing imagery. All products are available free of charge for the user community after a short registration process.
