StreamStats, a tool offering batch processing and web services for basin delineation and flow statistics, has seen a significant rise in usage, with 186,802 delineations and 151,134 gage reports in FY10. The upcoming user interface will incorporate ArcGIS 10 and JavaScript APIs, improving accessibility and functionality. Users can take advantage of various web services provided by StreamStats, including XML and KML outputs. Detailed instructions and resources for batch processing and web service requests are available at the StreamStats home page.

  8. Usage By State

  9. Batch PROCESSING AND web services

  10. StreamStats Web Services Available for: • Basin delineation • Basin Characteristics • Flow statistics from Regression Equations • Download • Used by Batch process See Available Web Services link from StreamStats home page for more information

  11. Web Services provided by StreamStats StreamStats Current Web Services • Output Formats • Extensible Markup Language (XML) • Keyhole Markup Language (KML) • Serialized ArcObjects(ESRI ArcGIS 9.2) • ArcGIS 10 GeoProcessing Service coming soon See users instructions at: http://streamstatsags.usgs.gov/webservices/ Use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.

  12. Web Services provided by StreamStats • HTTP GET Format http://streamstatsags.cr.usgs.gov/ss_ws_92/Service.asmx/getStreamstats?x=-111.1563&y=39.4725&inCRS=EPSG:6.6:4326&StateNameAbbr=UT&getBasinChars=C&getFlowStats=C&getGeometry=KML&downloadFeature=False&clientID=UT%20Demo

  13. Web Services provided by StreamStats What the request does • Computes the basin-drainage boundary at the X and Y point requested • Measures the drainage-basin characteristics for the computed basin-drainage boundary • Estimates Flows at the requested point using regression equations • Projects the points and polygon to WGS84 • Generates a KML file

  14. StreamStats Results in Google Earth

  15. Batch Processing • http://streamstatsags.cr.usgs.gov/ss_bp/ • Input: a point shapefile snapped to the stream grid • Uses Web Services to perform the computations • Emails the user when the output is available

  16. Batch Processing Preparing a dataset for use in the batch processor: • Download the stream grid for your state • Select the points needed for batch processing • Snap these points to the downloaded grid • Identify a field that contains your local id

  17. Batch Processing

  18. John Guthrie jdguthrie@usgs.gov DEVELOPMENT OF NEW USER INTERFACE

  19. Proposed new user interface • ArcGIS 10 • Uses ESRI map services for base map • JavaScript API • Uses Web Services • Can automatically determine which state application to call

  20. Proposed new user interface

  21. Proposed new user interface • Displays all regional studies and state applications near the point that was clicked

  22. Proposed new user interface

  23. Proposed new user interface • Stream Gage information is still available

  24. StreamStats in the cloud • It will have to be a big cloud
