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.

File Name: Web Page, url: https://www.fs.fed.us/rm/boise/AWAE/projects/NationalStreamInternet.html 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.

随着空间流网络模型（SSNMs）、流数据库的日益丰富以及地理空间科学和计算效率的持续进步，关于流资源新信息的产生速率得到了显著提升。为了进一步促进信息的发展，国家流互联网（NSI）项目应运而生，旨在提供一种一致且灵活的分析基础设施，该基础设施可应用于全国范围内多种类型的流数据。该基础设施的核心部分是NSI网络，这是一个具有特定拓扑结构的数字GIS层，专为与SSNMs的高效协同工作而设计。NSI网络是在确保与SSNMs兼容的技术程序指导下，从国家水文数据集Plus，版本2（NHDPlusV2）中派生出来的。SSN模型在处理流数据方面优于传统的统计技术，能够在未采样地点进行预测，为河流网络创建状态图，并且与来自多个来源的、包含聚类采样位置的数据库协同工作尤为出色。
NSI项目由美国鱼类和野生动物服务局景观保护合作项目资助，具有两个简单的目标：1）精炼关键的地理空间和统计流软件及数字数据库，以确保其兼容性，从而在全国范围内建立一个统一且易于应用的分析基础设施；2）吸引基层用户参与该基础设施的应用，使他们能够从全国各地的流数据库中创建新的、有价值的信息。本网站是一个枢纽，旨在将用户与软件、数据和工具连接起来，以创建此类信息。随着信息的不断完善，它应有助于增强与流生态系统相关的科学、管理和保护。
