Geobase of the Quebec River System (QHRM)
The Quebec Hydrographic Network Geobase (QHRM) is the common reference for hydrography in Quebec. It is a detailed hydrographic network that supports many applications in spatial planning, environment and civil security. The QRM is produced in partnership with the Ministère de l'Environnement et de la Lutte contre les changements climat (MELCC) and the Ministère de l'Énergie et des Ressources naturelles (MERN) using the following data: * The hydrographic classes of the Quebec Topographical Database (BDTQ) at a scale of 1:20 ,000 of the MERN for the south of Province; * CanVEC hydrographic classes at a scale of 1:50 ,000 of Natural Resources Canada for the North; * Continuity segments of the MELCC system; * Hydrographic cutting units of the MELCC; * Official place names of the TOPOS database of the Toponymy Commission. The main components are: _Geometric network_ * Points * Point components of the geometric network (hydrographic junctions) * Linear geometric network representing the continuity of flow across all types of hydrographic features (linear and polygon). _Thematic information_ * Points * Context feature class represented in point form that enrich the thematic content of the different hydrographic components. * Lines * Context feature class represented in linear form that enrich the thematic content of the different hydrographic components. * Feature class lines representing the edges of hydrographic surfaces. * Surfaces* A class of context features represented in polygon form that enrich the thematic content of different hydrographic components. * A polygon feature class representing the hydrographic surfaces. _Management Units_ * Surfaces* A polygon feature class representing hydrographic cutting units (UDU).
