| Description |
Maintained and distributed by the Swedish Meteorological and Hydrological Institute (SMHI) as a core base product of the Swedish Water Archive (SVAR / Svenskt Vattenarkiv, version SVAR 2016:8), this dataset (Vattendragslinjer_nätverk_2016.shp) provides Sweden's national topologically connected watercourse network. Originally derived from Lantmäteriet's 1:250,000 digital cartographic base (GSD-Översiktskartan) and refined by SMHI since 2005, it comprises 135,018 polyline features representing natural and artificial watercourses as well as synthetic flowlines routed through lakes and wide river polygons, each assigned a unique line ID, watercourse identity, and name. |
