  1. TEXAS SURFACE WATER QUALITY MONITORING INFORMATION SYSTEM GIS IN WATER RESOURCES CE 394K.3 David Trujillo November 21, 2006

  2. MOTIVATION Need information for a water quality study for Lake Texoma. Ideally you would look for data in a national database (EPA’s STORET)

  3. STORET STATIONS STORET contains data from the following Stations No Monitoring Stations in Texas? November 2004 EPA

  4. TCEQ SWQM STATIONS Texas has a very complete network of monitoring stations

  5. INTEGRATION If databases were integrated:

  6. EPA STORET • Repository of marine, freshwater and biological monitoring data • Developed in the 1960’s • Currently two systems: Legacy (1998) and Modernized • Users: Federal, State, Local, Tribes, Academia, Groups

  7. EPA STORET Updated once a month

  8. TCEQ TRACS-SWQM • Texas equivalent of STORET since 1967 • 8,300 monitoring stations • Government, River Authorities, Organizations, etc. • ASCII Files:

  9. CURRENT STATUS • Need to maintain a local STORET database • Legacy Data Format • STORET is very complex • STORET doesn’t conform the needs of the State • Different data standards

  10. FUTURE INTEGRATION SWQMIS • Replace outdated system • Meet business needs • Provide efficient access to public • Analysis Tools • Enhanced Queries EPA WQX • January 2007, September 2009 • Internet Submittals • New front-end, tools • XML

  11. Response WQX Validate Header (.xml) Other Header Payload WQX Doesn’t require states to run EPA software

  12. eXtensible Markup Language • Definition, transmission, and validation of data between systems • XML schema are the files that define data elements and structure Example converting from ASCII to XML L703568,01-10-2006,00945,pH,5.5 <document> <row> <OrganizationIdentifier>L703568</OrganizationIdentifier > <EventDate>01-10-2006</EventDate > <EventEndTime>00945</EventEndTime > <Parameter>pH</Parameter > <Value>5.5</Value > </row> </document> http://www.creativyst.com/cgi-bin/Prod/15/eg/csv2xml.pl

  13. WQX XML Schema

  14. FUTURE WORK • Legacy Data Integration Abstraction Layer Appear Unified CUAHSI- Large Amounts of Data Database Migration Open Database Connectivity (ODBC) Convert Parameters (STORET 9000+)

  15. FUTURE WORK • Mapping Applications • Example: Search Wizard Developed by: Bora Beran, Drexel University
