Hydroinformative products aim at integrating data from different sources in decision supporting information products. FutureWater integrates Geographical Information Systems (GIS), Remote Sensing data, output from simulation models and other data in information and communication applications that can be used for decision support at various levels, ranging from small-scale operational services to large river basin scale strategic decision support tools.The abundance of climatological, hydrological, and remote sensing data in the public domain nowadays calls for superior data analysis, data handling, data management and data integration methodologies to translate scientific data to knowledge products that are informative, intuitive, understandable and supportive in decision making. Hydroinformatics is a technology built around developments and applications of systems which are, for their users, objective systems. A tool is objective if the users are involved in its definition, if they can easily understand the results and use them, if they have the possibility to input their own hypotheses into the system and see the consequences – as well as to show these to other stakeholders.
