Open source development of environmental and engineering cyberinfrastructure


HydroServer is a set of software applications for publishing hydrologic datasets for an experimental watershed or site on the Internet. HydroServer leverages commercial software such as Microsoft SQL Server and ESRI's ArcGIS Server as well as versions that run on more open platforms using Linux and open relational database management systems like MySQL. HydroServer is now being used in production as part of CUAHSI's Water Data Services.
