The National Stream Internet project
The rate at which new information about stream resources is being created has accelerated with the recent development of spatial stream-network models (SSNMs), the growing availability of stream databases, and ongoing advances in geospatial science and computational efficiency. To further enhance information development, the National Stream Internet (NSI) project was developed as a means of providing a consistent, flexible analytical infrastructure that can be applied with many types of stream data anywhere in the country. A key part of that infrastructure is the NSI network, a digital GIS layer which has a specific topological structure that was designed to work effectively with SSNMs. The NSI network was derived from the National Hydrography Dataset Plus, Version 2 (NHDPlusV2) following technical procedures that ensure compatibility with SSNMs. The SSN models outperform traditional statistical techniques applied to stream data, enable predictions at unsampled locations to create status maps for river networks, and work particularly well with databases aggregated from multiple sources that contain clustered sampling locations.
The NSI project is funded by the U.S. Fish & Wildlife Service's Landscape Conservation Cooperative program and has two simple objectives: 1) refine key spatial and statistical stream software and digital databases for compatibility so that a nationally consistent analytical infrastructure exists and is easy to apply; and 2) engage a grassroots user-base in application of this infrastructure so they are empowered to create new and valuable information from stream databases anywhere in the country. This website is a hub designed to connect users with software, data, and tools for creating that information. As better information is developed, it should enable stronger science, management, and conservation as pertains to stream ecosystems.

The National Stream Internet (NSI) is a network of people, data, and analytical techniques that interact synergistically to create information about streams. Elements and tools composing the NSI, including STARS, NHDPlusV2, and SSNs, enable integration of existing databases (e.g., water quality parameters, biological surveys, habitat condition) and development of new information using sophisticated spatial-statistical network models (SSNMs). The NSI provides a nationally consistent framework for analysis of stream data that can greatly improve the accuracy of status and trend assessments. The NSI project is described, together with an analytical infrastructure for using the spatial statistical network models with many types of stream datasets.
