OGC Seeks Public Comment on OGC WaterML 2 – Part 3, Surface Hydrology Features Conceptual Model

The membership of the Open Geospatial Consortium (OGC®) seeks public comment on its WaterML 2 – Part 3, Surface Hydrology Features Conceptual Model.

The OGC WaterML 2 – Part 3, Surface Hydrology Features Conceptual Model (HY_Features) is part of an intended ‘OGC WaterML 2’ suite of standards that groups water-related OGC standards. The candidate standard follows Part 1: Timeseries, and Part 2: Ratings, Gaugings and Sections.

The candidate HY_Features standard defines a common feature model for the identification and description of surface hydrologic features. The feature model is based on established models and patterns in use in the Hydrology domain and endorsed by WMO and UNESCO, such as those documented in the “International Glossary of Hydrology.”

The candidate HY_Features standard also defines a common conceptual information model for surface hydrologic features independent of their geometric representation and scale. The model describes fundamental relationship types that exist among major components of the hydrosphere. This includes relationships such as hierarchies of catchments, segmentation of watercourses, and topological connectivity of hydrologic features based on the flow and conservation of water.

The standard is intended to be used to document and share information about real-world objects that are studied in a wide range of hydrologic study types. The original design goal for HY_Features was to link hydrologic information across the scientific and technical programs of organizations with local to global scope, and to assist in discovery, access, and use of hydrologic data from different sources.

The HY_Features model is designed to support many types of hydrologic information and sub-disciplines. The model supports referencing information about a hydrologic feature across disparate information systems or products, thereby improving data integration within and among organizations. Similarly, the model can be applied to cataloging of observations, model results, or other study information involving hydrologic features. The ability to represent the same catchment, river, or other hydrologic feature in several ways is critical for aggregation of cross-referenced or related features into integrated datasets and data products on global, regional, or basin scales.

Agreement on common concepts and methods is necessary to enable semantic interoperability of hydrologic data and services. The HY_Features model was developed in order to formalize concepts and relationships of hydrologic and hydrographic features using the WMO/UNESCO “International Glossary of Hydrology” as a starting point.

The candidate standard is available for review at  portal.opengeospatial.org/files/?artifact_id=72353&version=3. Comments are due by 16 February 2017 and should be submitted to  Email Contact.

About the OGC

The OGC is an international consortium of more than 525 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC standards support interoperable solutions that “geo-enable” the Web, wireless and location based services, and mainstream IT. OGC standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.
