Developing a Service Oriented Architecture for the NHDPlus

This project makes available existing complex NHDPlus network traversals tools coupled with Framework Web Feature Service (WFS) extraction tools in a Service-Oriented Architecture (SOA) to further advanced geospatial analysis with the Connecticut River Watershed and Framework datasets.

This project continues to build upon the Connecticut River Watershed Atlas to support the science priorities of creating data-sharing and geospatial analysis systems. The results of this project provide useful geospatial analysis tools within desktop GIS applications for the other science priorities associated with Connecticut River Watershed sustainability - water budgets, water quality, and ecological flow determinations. In addition, the project provides useful training and distribution of software tools to federal, state, local, academia, private sector, and non-profit organizations, such as the USGS, EPA, and The Nature Conservancy, through training and presentations at local and national geospatial-related events and the Internet. A Service-Oriented Architecture (SOA) has been implemented as the foundation for the NHDPlus navigation tools and the Framework Web Feature Service GIS toolset for a client desktop. The toolset allows users to view near real-time gauging station information, build watershed boundaries from upstream/downstream reaches identified via network tracing, create attribute reports, and download/extract NHDPlus from a WFS.
