Linked Spatial Web Data and Ontology Applications in Surface Water Hydrology
By Josh Lieberman, senior research scientist at CGA.
Thursday, December 1, 2016. Noon - 1:30. Room S354, CGIS South building, 1730 Cambridge St.
Abstract: Effective spatial data use on the Web means being able to link disparate data elements such as features and geometry across the Web. Spatial data interoperability across the Web requires both a common model and vocabulary of spatial concepts. The presentation will cover a number of vocabularies developed in RDF/OWL to communicate both general spatial concepts and the specific entities involved in the study and mapping of surface water features in the U.S. and elsewhere. Linked data mechanisms and RDF/OWL ontologies allow such data not only to be “webified” and distributed widely, but also fit well with the multi scale and diverse network representations of hydro features. Tools will be covered that enable transformation of relational hydro data into linked data, publication, mapping, and analysis.
