Geologischer Atlas der Schweiz 1:25000 – Profile

The GA25-Profile dataset (GA25_CS) is a compilation of the cross sections published together with the Geological Atlas 1:25,000. It depicts the cross section tracks and contains metadata on the cross sections. The given year of issue corresponds to the publication year of the respective explanatory notes. The cross sections represented by the tracks were extracted from the published cross section plates and, if possible, saved individually along with the entire plate legend and scale as a PDF. Since the legend always refers to the entire plate, it is likely that not all elements of the legend appear in the individual cross section. In a few cases, plates with very closely spaced cross sections cannot be subdivided into single cross sections. In these cases, the entire plate is shown for each group of the cross section tracks.

Air navigation obstacles - Changes of the last 56 days

Air navigation obstacles - Changes of the last 56 days

Representation of the new air navigation obstacles, which have been activated during the last 56 days. This timeframe covers maximum two cycles of 28 days, which represents the standard for regular updates of aeronautical information publications (AIRAC). The newly activated air navigation obstacles are updated daily. Air navigation obstacle data are data on the obstacles defined in Article 2 letter k of the Ordinance of 23 November 1994 on Aviation Infrastructure (VIL, SR 748.131.1). Air navigation obstacles are structures and installations (such as antennas, buildings, cables, cranes, cableways, power lines, wind turbines) and vegetation that can hamper, endanger or prevent the operation of aircraft or of air navigation systems. The data are gathered as part of the authorisation requirement under Art. 63 VIL, and the registration requirement under Art. 65a VIL. With the exception of vegetation, the present data set includes all permanent and temporary air navigation obstacles with a height of 25 m or more outside built-up areas (or 40 m or more in the case of mobile cranes), and in built-up areas, obstacles with a height of 60 m or more.
