swisstopo know-how

Pupils will gain valuable knowledge about points, positions and satellites in videos provided by swisstopo. The educational programmes convey important information about cadastral surveying.

In the swisstopo know-how range of videos, complex subject matter about cadastral surveying is made simple. The educational programmes are aimed at secondary school stage II pupils and their teachers, at both grammar and vocational schools. All tutorials are available on YouTube.

Global coordinate system

In the short film about the global coordinate system, pupils delve into the world of points and their positions. They familiarise themselves with longitude and latitude and learn why Switzerland is located at 47° north. The universal World Geodetic System 1984 (WGS84) reference system and its significance for surveying are also explained in the video. 

Swiss coordinate system

An additional video covers the Swiss coordinate system, known as the Swiss national land survey 1995 (LV95). Pupils learn why this system is right-angled and what it is used for. Locations in Switzerland are used to illustrate specific coordinates. The learning is very simple to apply practically in the lesson: Swiss national coordinates can be entered and searched on map.geo.admin.ch.

Introduction to height measurement systems

The Introduction to heights measurement systems tutorial addresses a different type of measurement. The film explains physical and geometric heights, enabling pupils to gain an understanding of the distinction between the units. The role of navigation systems, which receive satellite signals, is also touched upon. Finally, pupils learn how precisely experts at swisstopo can measure elevation using the CHGeo2004 system and why this is of great importance to the construction of roads and railways and hydraulic engineering.
