Urban Topographic Mapping 1:1,000: Hydrography — polygons

Hydrographic layer of the Urban Topographic Cartography 1:1,000 with polygon geometry.Map of surface geographical entities attached to the subject of hydrography (according to model of mapping data). It consists of aggregation of all water bodies of the hydrographic network and associated hydraulic infrastructure that is collected in the map sheets of the Urban Topographic Cartography series 1:1,000. It collects all those river courses, natural and artificial, of a width greater than 3 meters. Also the bodies of water retained naturally, in the case of lakes, lagoons and ponds, and artificially, the case of the reservoir.
