It provides geospatial digital data compliant with the NHN Standard such as lakes, reservoirs, watercourses (rivers and streams), canals, islands, drainage linear network, toponyms or geographical names, constructions and obstacles related to surface waters, etc. The best available federal and provincial data are used for its production, which is done jointly by the federal and interested provincial and territorial partners. The NHN is created from existing data at the 1:50 000 scale or better. In particular, the modelling work of the NHN was based on Linear Reference System (LRS) concepts. This approach allows the management of geometric representation separately from attribute information (referred to as event in LRS). Unique Identifiers are associated with each geometric and event object. These IDs (called National Identifiers - NIDs) will lead to more efficient management of updates between data producers and data users. The NHN data have a great potential for analysis, cartographic representation and display and will serve as base data in many applications.", "geometryType": "esriGeometryPolygon",
