| 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 (Vattenytor_2016.shp) provides Sweden's authoritative national polygon inventory of lakes and wide river surface water bodies. Originally derived from Lantmäteriet's 1:250,000 digital cartographic base (GSD-Översiktskartan) and refined by SMHI since 2005, it comprises 42,178 polygon features linked to SMHI's sub-basin and watercourse identities. |
