1. Introducing the CUAHSI Hydrologic Information System Desktop Application (HydroDesktop) and Open Development Community Jiří Kadlec, Daniel Ames, Teva Velupillai Jeff Horsburgh Idaho State University Utah State University Some Slides Courtesy of the CUAHSI HIS Project Team

2. 2 Talk Overview Hydrologic Information System HydroDesktop Application MapWindow GIS Components Community Development

3. 3 What is HIS? The CUAHSI* Hydrologic Information System (HIS) provides web services, tools, standards and procedures that enhance access to more and better data for hydrologic analysis. http://his.cuahsi.org *Consortium of Universities for the Advancement of Hydrologic Science, Inc. http://www.cuahsi.org http://www.cuahsi.org

4. 4 Rainfall & Snow Water quantity and quality Remote sensing Water Data Modeling Meteorology Soil water

5. 5 Metadata Catalog HIS Central HydroDesktop HIS System Overview Users Data Discovery Data Access Data Registration USGS EPA Data HIS Servers Data Web Service Universities Data

6. 6 Built for data – Storage – Loading – Analysis – Publication HIS Software free of charge HIS Server Real-time Sensors WaterOneFlow Web Service Data Archives Outside Users, HIS Central, HydroDesktop Local Users ODM Tools HIS Server SQL Server Observations Data Model Database

7. 7 Stores metadata – S ites –Variables –Search Keywords Does not store actual observation data Example: GetSitesInBox query function HIS Central HICentral Web Service

8. 8 Getting Water Data (the old way) Different Query Pages Different Query Responses

9. 9 Web Pages versus Web Services http://www.safl.umn.edu/ http://his.safl.umn.edu/SAFLMC/cuahsi_1_0.asmx Uses Hypertext Markup Language (HTML) Uses WaterML (a Markup Language for water data)

10. 10 HTML as a Web Language Text and Pictures in Web Browser Texas Water Development Board HyperText Markup Language

11. 11 WaterML as a Web Language Graphical display of streamflow data Streamflow data in WaterML language

12. 12 HydroDesktop Client Application

13. 13 HydroDesktop Capabilities Add shapefiles to map Change symbology and labels Print and export map GIS toolbox GIS Search for data Download data Display time series Export data Hydrology

14. 14 HydroDesktop Data Search Where? (geographic region) What? (variable – keyword) When? (time range) Who? (data providers) Search Criteria Precipitation and air temperature in the Columbia river basin, 2008 - 2009 Example:

15. 15 HydroDesktop Data search – select region Draw bounding box Select polygons Select Country Select State Select County Select Watershed Region selection

16. 16 HydroDesktop Data search – select keywords

17. 17 HydroDesktop data search – Select time range and data services

18. 18 HydroDesktop Data search – Search Results Precipitation and Temperature, Columbia River Basin
