Road map of the Czech Republic 1:50,000

Road Map of the Czech Republic 1:50 000 (SM 50) is a multicolour overprint of thematic content onto the Base Map of the Czech Republic 1:50 000 (ZM 50). The thematic content includes motorways, roads with their classification, motorway and road numbers, nodes of the localisation system of the road database (LS SDB), grade-separated interchanges, bridges, underpasses, level railway crossings, tunnels, ferries, curves, gradients, passes and kilometrage at 1 km intervals, etc. Each map sheet contains a map legend with a selection of the most commonly used map symbols. The map is published in cooperation with the Road and Motorway Directorate of the Czech Republic, which also determines the edition plan and authorises the printing and reprinting of maps (reprinting of maps published before 2004 is not possible for technical reasons).
