CUAHSI HIS
The CUAHSI Hydrologic Information System (HIS) is an internet based system
to support the sharing of hydrologic data. It is comprised of hydrologic
databases and servers connected through web services as well as software for
data publication, discovery and access.

HydroServer Goals
• A platform for organizing and publishing
space-time hydrologic datasets that:
– Provides local control of data
Put the data service as
close to the data
producer as possible.
– Makes data universally available
Share the data as
widely and openly as
possible.
– Is autonomous – e.g., functional
independent of the rest of HIS
Serve as a useful data
store regardless of
the fate of CUAHSI
HIS.

Publishing Data in an ODM Database
WaterML and WaterOneFlow
WaterML is an XML schema for communicating water data
WaterOneFlow is a set of web services based on WaterML
• Set of query functions
• Returns data in WaterML
Slide from David Valentine
For example: to get a site, send this “SOAP” request
to the server:
Specify the site and an optional
authorization token
Get this response:
Result returns in this string.
2 Flavors of HydroServer:
HydroServer (.NET)
• HydroServer (.NET):
• http://hydroserver.codeplex.com
• Model implementation of the HydroServer CUAHSI HIS
specification
• Runs on Windows servers
• Requires Microsoft SQL Server
• Uses ArcGIS Server
• Uses Streaming Data Loader, Data Loader and SQL tools to
manage the database.
2 Flavors of HydroServer
• Original HydroServer:
• http://hydroserver.codeplex.com
• Model implementation of the
HydroServer CUAHSI HIS specification
• Runs on Windows servers
• Requires Microsoft SQL Server
• Uses ArcGIS Server
• Uses Streaming Data Loader, Data Loader
and SQL tools to manage the database.
• HydroServer Lite:
• http://hydroserverlite.codeplex.com
• Simplified implementation of the CUAHSI
HIS specification (all required services are
supported).
• Runs on the free LAMP stack (Linux,
Apache, MySQL, PHP)
• Uses front end web pages to load data in
the database.
HydroServer PHP (HydroServer Lite)
• HydroServer Lite:
• http://hydroserverlite.codeplex.com
• Simplified implementation of the CUAHSI HIS
specification (all required services are supported).
• Runs on the free LAMP stack (Linux, Apache, MySQL,
PHP)
• Uses front end web pages to load data in the database.
What is HydroServer Lite?
• PHP and MySQL mean easy/fast/cheap setup
• Focus on easy extends to user interfaces.
• Developer community at
http://hydroserverlite.codeplex.com/
• Let’s try it out: http://worldwater.byu.edu/
• Browse data from any database, upload data
using the “sandbox” database.
