The term hydrolink is being defined as the linkage of spatial data to a stream network. This is similar to the analogy of providing an address on a road network and provides locational context and position within a stream network. Hydrolinking data to a common stream network allows information to be centralized helping support landscape scale analyses and modeling efforts. Versions of the National Hydrography Dataset are often used as a spatial framework for modeling and describing aquatic biological and hydrologic systems at larger geographic scales.
Abundant data are currently available to describe aquatic systems, yet systematic, efficient, and accurate methods to hydrolink thousands or millions of data points are limited. This Python package contains methods and a command line tool that help hydrolink geospatial information to the National Hydrography Datasets. Further, these methods help provide levels of certainty that can be helpful to determine where code-based methods are sufficient and when manual review for quality is warranted.
