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

Batch processing
Batch Processing


  • Input: a point shapefile snapped to the stream grid

  • Uses Web Services to perform the computations

  • Emails the user when the output is available

Batch processing1
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

Development of new user interface

Proposed new user interface
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

Proposed new user interface2
Proposed new user interface

  • Displays all regional studies and state applications near the point that was clicked

Proposed new user interface4
Proposed new user interface

  • Stream Gage information is still available

  • It will have to be a big cloud
