Overview of triangulation station and net densification point 1:50,000

Overview of triangulation stations and net densification points 1:50,000 (PTZB 50) is a multicoloured reprint of thematic content into the suppressed Base map of the Czech Republic 1:50,000.
The subject of the thematic content is a layout of territorial inventory units, ie triangulation sheets in S-JTSK, their designation and location of all trigonometric points, orientation points (OB1, OB2), net densification points and associated points. Points surveyed in ETRS 89 are differentiated by colour. The overview is supplemented by the division into map sheets of the State Map 1:5,000.
Each map sheet contains a map legend with the selection of the most common map symbols. Currently, PTZB 50 is only printed on order.
