Abstract

NHDPlus Navigation and Reporting Toolset for Connecticut River Watershed Atlas
Track: Water Resources
Author(s): Craig Johnston, John Waterman

A Service-Oriented Architecture (SOA) toolset has been developed for the Connecticut River Watershed Atlas. The toolset includes WFS feature extraction, flow line navigation. and watershed-based NHDPlus reporting.

The benefits of the proposed toolsets allow organizations to perform geospatial analysis based on watershed boundaries generated on-the-fly via the NHDPlus Navigation tools. With the NHDPlus Navigation tools, users will be able to access detailed watershed information for approximately 12,500 stream segments of the NHDPlus in the Connecticut River Watershed. The ability to access specific watershed information and conceptualize their physical boundaries in relation to other datasets is unprecedented. The SOA will include a web application and ArcGIS Explorer clients. ArcGIS Server 9.3 beta technology will be used as the foundation for geospatial analysis and WFS feature extraction. This project has been funding by an NSDI 2008 CAP grant and implemented through collaboration between USGS, EPA, GCS Research, and Horizon Systems.
