Unifying hydrological time series data for a global water portal

The hydrological observation data is important for hydraulic engineers. They have to use the obtained information to control quality or quantity of water in the river system. Nowadays plenty of hydrological information systems are available. However there are many difficulties to do the parallel accesses between those services, for example, they not only require different approaches to access information, but also return different formats of information as output. Therefore, this work proposes a new design of Data Exchange Template, namely Data Consumer Model (DCM) as a filtering and unify format of the observed time series. This work analyzes on three hydrological information services that have many different factors to proof that proposed solution can work. Finally, the experiment results demonstrate that the DCM is able to access experiment services by simple method. It provides simple and unified format of attributes that used in communication between hydrological systems.
