OS Open Rivers consists of two core features:
WatercourseLink – A feature which represents all or part of a watercourse.
HydroNode – A feature which represents a river’s source, end, or where three or more links meet at a junction, and places where the real-world related attribution recorded changes, for example, a watercourse becoming tidal.
This product is based upon the INSPIRE Data Specification on Hydrography. The result is a product that inherits attribution from INSPIRE. An overview of the product's structure can be found in Figure 3 below, which highlights the inherited INSPIRE feature types and attribution. Properties of the INSPIRE specification which are voidable are not included in the diagrams or tables that follow. For information on the INSPIRE properties which are not included in this product, please see the INSPIRE Data Specification on Hydrography.
GML attribute naming is used in the main text of this guide. GeoPackage and vector tile attribute naming is very similar to GML as there are no character-length limitations in the GeoPackage or MBTiles formats. However, shapefile attribute naming is limited to 11 characters.
Attribute mappings between GML and shapefile are provided in the Esri shapefile overview.
Attribute mappings mapping between GML and GeoPackage are provided in the GeoPackage overview.
Attribute mappings between GML and Vector tiles are provided in the Vector tiles overview.
