Abstract

Several computer-based information and decision support systems have been developed to provide environmental and hydrological information in a timely manner. The Finnish Environmental Administration has used VMS/VAX-based application since late-80’s, but the present system is not anymore capable to fulfill the informational and functional needs being addressed by the users. At the Finnish Environment Institute we have studied different solutions to build up a new comprehensive hydrological information and decision support system. WWW-technology based solution has been chosen Although the new complex technology has required training it gives a great possibility to develop an effective and user-friendly system for our purposes. The requirements of the system are high: the hydrometric network is wide, there are over thousand potential users, and in addition to data storage and browsing the system has to include wide range of tools for statistical analysis, tools for calculation procedures needed in water resources management and tools for presenting graphical plots and GIS-data. Software solutions in our system are mainly based on Microsoft-technology (NT4.0, IIS, ASP, MTS, DCOM and SQLServer). The GIS-maps are provided by the technology of ESRI (MapObjects, Internet Map-Server). Because of various type of use the system is developed to be a cross-browser application without any plug-ins.
