HydroServer

HydroServers are the part of the HIS system that stores and publishes hydrologic data. It is one of the 3 main pieces of the HIS system and it communicates with the other parts using WaterOneFlow web services.

Standard HydroServer Configuration

There are numerous ways to set-up servers that meet some or all of the requirements necessary to function as a HydroServer, but the HIS project has identified a standard configuration using a combination of readily availabe off-the-shelf software including Microsoft SQL Server and ESRI's ArcGIS Server and a set of tools that have been developed by the HIS team.

 

These commercial products must be installed first:

• Microsoft Windows 2008 Server
• Microsoft ASP.NET 2.0
• Microsoft SQL Server 2008
• ESRI ArcGIS 9.3.1 Desktop
• ESRI ArcGIS Server 9.3.1 for .Net, Enterprise Advanced

and then these HIS developed components are installed:

• ODM Database — Data structure for storing data
• ODM Tools — Tool for data manager access for viewing, analyzing, and editing data
• ODM Data Loader — Tool for loading data (optimized for data with one data value per row)
• ODM Streaming Data Loader — Tool for loading data (optimized for data with one time step per row)
• WaterOneFlow Web Services — Provides the WaterOneFlow web services
• Capabilities Database, Capabilities Database Configuration Tool and Capabilities Web Services — Provides the tools, data structures and web services to publish the capabilities of the HydroServer
• HydroServer Web Site — Provides the HydroServer's general website
• HydroServer Time Series Anlayst — Web application linked into the HydroServer's website that allows the user to view and analyze the observation data
• HydroServer Map Web Application — Web application linked into the HydroServer's website that allows the user to view and analyze the spatial data

 

HydroServer Development

HydroServer is a specifications-based system where the basic functionality and interfaces are defined, but many specific configurations can be developed that meet the specifications, and the standard configuration software for the HIS Standard HydroServer Configuration is being developed as an open source project. This makes for many opportunities to both develop your own configuration as well as to help develop the standard configuration.
