  1. The HydroServer Platform for Sharing Hydrologic Data David G Tarboton, Jeffery S Horsburgh, Kimberly A. T. Schreuders, David R. Maidment, IlyaZaslavsky, David Valentine http://his.cuahsi.org/ CUAHSI HIS Sharing hydrologic data Support EAR 0622374

  2. CUAHSI Hydrologic Information System Services-Oriented Architecture Data Discovery and Integration HydroCatalog Search Services Metadata Services WaterML, Other OGC Standards HydroServer HydroDesktop Data Analysis and Synthesis Data Publication Data Services ODM Geo Data Information Model and Community Support Infrastructure

  3. HydroServer – Data Publication Point Observations Data Internet Applications Ongoing Data Collection Historical Data Files ODM Database GetSites GetSiteInfo GetVariableInfo GetValues GIS Data WaterML WaterOneFlow Web Service OGC Spatial Data Service from ArcGIS Server Data presentation, visualization, and analysis through Internet enabled applications

  4. HydroServer Architecture Service Interface Publish point data Publish metadata Publish spatial data Manager Interface Browser Interface HydroServer View server portal WaterOneFlow Web Service Capabilities Web Service Spatial Data Services HydroServer Website WaterOneFlow Web Service WaterOneFlow Web Service Load and Edit data ODM Tools and Data Loaders Observation DataModel View spatial data Geo Spatial Database Map Website Observation DataModel Observation DataModel Spatial Data File HydroServer Capabilities Database Capabilities Configuration Tool Configure server View point data Time Series Analyst Website

  5. Observation Data Model for hydrologic and environmental measurements The way that data is organized can enhance or inhibit the analysis that can be done Groundwater levels Streamflow Precipitation & Climate Soil moisture data Flux tower data Water Quality • A relational database at the single observation level • Metadata for unambiguous interpretation • Traceable heritage from raw measurements to usable information • Promote syntactic and semantic consistency • Cross dimension retrieval and analysis Horsburgh et al., 2008, WRR 44: W05406

  6. Stage and Streamflow Data in ODM

  7. Loading data into ODM OD Data Loader • Interactive OD Data Loader (OD Loader) • Loads data from spreadsheets and comma separated tables in simple format • Scheduled Data Loader (SDL) • Loads data from datalogger files on a prescribed schedule. • Interactive configuration • SQL Server Integration Services (SSIS) • Microsoft application accompanying SQL Server useful for programming complex loading or data management functions SDL SSIS

  8. Managing Data Within ODMODM Tools • Query and export – export data series and metadata • Visualize – plot and summarize data series • Edit – delete, modify, adjust, interpolate, average, etc.

  9. Set of query functions ReturnsdatainWaterML WaterML and WaterOneFlow WaterML is an XML language for communicating water data WaterOneFlow is a set of web services based on WaterML

  10. Publication of Spatial (GIS) Datasets • Publishing spatial datasets using ArcGIS Server • Using OGC standards that can be consumed by a number of GIS clients • WMS, WFS, WCS

  11. Data Presentation Via a Map Interface • Internet Map Server built using ArcGIS • Web browser client • Combine spatial data and observational data • Launch data visualization tools • Based on a “Region” http://maps.usu.edu/map/

  12. Data Preview, Visualization, and AnalysisTime Series Analyst • Web Browser Client • Multiple ODM Database Support • Variety of plot types • Descriptive statistics • Linked to the map application • Data preview and download http://icewater.usu.edu/tsa/

  13. HydroServerWebsite • HydroServer home page • Observational data services • GIS data services • Online map • Time Series Analyst • Data Query and Download http://icewater.usu.edu

  14. HydroServer Capabilities Web Service • Publish capabilities of each HydroServer • Listing of published observational data services • Listing of published spatial data services • Supports automatic cataloging of available services at HIS Central • Makes HydroServers self describing Catalog Catalog Services Metadata Services Data Services Server Desktop

  15. Overcoming Semantic Heterogeneity • ODM Controlled Vocabulary System • ODM CV central database • Online submission and editing of CV terms • Web services for broadcasting CVs ODM VariableNameCV Variable Name From Jeff Horsburgh

  16. Dynamic controlled vocabulary moderation system ODM Data Manager ODM Website ODM Tools ODM Controlled Vocabulary Moderator XML Master ODM Controlled Vocabulary Local ODM Database ODM Controlled Vocabulary Web Services Local Server http://his.cuahsi.org/mastercvreg.html From Jeff Horsburgh

  17. Dry Creek Experimental Watershed (DCEW) (28 km2 semi-arid steep topography, Boise Front) A growing collection of HydroServers and community of users • University of Maryland, Baltimore County • Montana State University • University of Texas at Austin • University of Iowa • Utah State University • University of Florida • University of New Mexico • University of Idaho • Boise State University • University of Texas at Arlington • University of California, San Diego • Idaho State University 68 Sites 24 Variables 4,700,000+ values Published by Jim McNamara, Boise State University

  18. Open Development Model http://hydroserver.codeplex.com • user engagement • transparency • collaboration • agility • sustainability • tools

  19. Conclusions • HydroServer provides a self contained data publication system • Self describing (Complete description of data and metadata) • Local control of, and responsibility for data • Downloadable user (data publisher) configurable software stack • ODM and tools, Web service software, Time Series Analyst, ArcGIS server based web map application and map services, HydroServer Capabilities metadata web services • Sharing data in common format can stimulate interdisciplinary collaboration • Growing network of HydroServers will facilitate cross site network scale syntheses Catalog Catalog Services Metadata Services Data Services Server Desktop
