|Definitionskos:definition||Over the past few years there has been an increase in the number, size and complexity of databases across government sectors. This has undoubtedly created challenges relating to the discovery and access of information and services on multiple databases across static and deployed networks. Linked Data has been suggested as a method able to tackle those challenges. The aim of the Hydrographic Linked Data activity in the OGC Testbed 11 was to advance the use of Linked Data for hydrographic data by building on the achievements of the previous testbeds and to improve the understanding of how to better build relations between hydro features and non-hydro features (e.g., stream gauge measurement/location vs bridge or other built features upstream or downstream). This aspect of the testbed focused on the National Hydrography Dataset (NHD) which is published by the United States Geological Survey (USGS). This OGC Engineering Report provides guidelines on the publication of hydrographic and hydrological data serialized as Resource Description Framework (RDF) using Linked Data principles and technologies based on OGC standards. The document also presents the experimentation conducted by Testbed 11 in order to identify those guidelines.|
