This project seeks to make 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.

The project builds upon the Connecticut River Watershed Atlas to support the science priorities of creating data-sharing and geospatial analysis systems. The results of this project will 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, provide useful training and distribution of software tools to federal, state, local, academia, private sector, and non-profit organizations, such as the USGS, EPA, The Nature Conservancy, through training and presentations at local and national geospatial related events and the Internet.

A Service-Oriented Architecture (SOA) will be implemented as the foundation for the proposed NHDPlus navigation tools and Framework Web Feature Service client desktop GIS toolset (see figure below). Without the need for local copies of GIS data, the toolsets will allow users to build watershed boundaries from upstream/downstream reaches identified via network tracing; download and extract Framework fully functional local geospatial vector data based on watershed boundaries and other areas of interest; to support complex geospatial analysis against the Framework, Atlas, and related datasets, such as water quality modeling, pollutant transport modeling, streamflow estimation, water resource management, and ecological modeling and assessment.
