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.

Hydro. Server 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 Water. ML and Water. One. Flow Water. ML is an XML schema for communicating water data Water. One. Flow is a set of web services based on Water. ML • Set of query functions • Returns data in Water. ML 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 Hydro. Server: Hydro. Server (. NET) • Hydro. Server (. NET): • http: //hydroserver. codeplex. com • Model implementation of the Hydro. Server CUAHSI HIS specification • Runs on Windows servers • Requires Microsoft SQL Server • Uses Arc. GIS Server • Uses Streaming Data Loader, Data Loader and SQL tools to manage the database.

2 Flavors of Hydro. Server • Original Hydro. Server: • http: //hydroserver. codeplex. com • Model implementation of the Hydro. Server CUAHSI HIS specification • Runs on Windows servers • Requires Microsoft SQL Server • Uses Arc. GIS Server • Uses Streaming Data Loader, Data Loader and SQL tools to manage the database. • Hydro. Server 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, My. SQL, PHP) • Uses front end web pages to load data in the database.

Hydro. Server PHP (Hydro. Server Lite) • Hydro. Server 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, My. SQL, PHP) • Uses front end web pages to load data in the database.

What is Hydro. Server Lite? • PHP and My. SQL 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.

Internationalization Effort

Try it… • • • Go to worldwater. byu. edu Databases Sandbox Create a new site Add the data to your site from the sample data zip file on Canvas

Try it… • Format your USGS data from Tuesday’s class • Create a new site for this data. • Upload your data! • http: //goo. gl/m. R 6 uwb

Assignment • Build your own Hydro. Server instance • Use Hydro. Server. NET or Hydro. Server PHP • Install on your own server or use worldwater. byu. edu • Upload your own observations • Write a brief report…
