Hydrography

Hydrography includes data on running and standing waters and on built and other water-related facilities. The hydrography point data layer contains elements (facilities, segments) of hydrography that are covered by point geometry (e.g. waterfall, spring, sink, dam, lock, stage, etc.). Linear hydrography data layer – surface waters contain surface waters covered by line geometry (e.g. watercourse, channel, reservoir, drainage ditch, etc.). Linear hydrographic data layer – objects and others contain objects and other parts of surface water covered by line geometry (e.g. waterfall, lock, embankment, dam, tier, etc.). The surface hydrography data layer – surface waters contains surface waters covered by a surface geometry (e.g. watercourse, channel, reservoir, lake, reservoir, recreation pool, etc.). The surface data layer of hydrography – objects and others contains objects and other parts of surface water covered by the surface geometry (e.g. dam, coastal structure, pebble, lock, etc.).
