Webinar Details

Discover the Network Linked Data Index (NLDI)—a search engine that indexes data to a river network —and its applications for data producers, application developers, data analysts, and modelers.  A vital component of several USGS web systems as well as the growing index of data in Geoconnex (the Internet of Water’s core technology), the NLDI has been key to unveiling relationships between single monitoring locations and the broader water world. Now, following a recent effort to convert the code base to Python to increase open-source accessibility, it’s set to make water data even more discoverable and easily accessible. Join this webinar to learn more about the NLDI’s past as a groundbreaking EPA and USGS collaboration, and its future, including the development of client applications in the USGS Monitoring Location pages and Water Quality Portal. The presentation will be targeted at both a technical and non-technical audience.
