Generalised borders

Administrative borders which have a low level of detail are often needed for thematic maps and representations on a small scale. The digital boundaries of Switzerland and the Principality of Liechtenstein, which are updated annually by the Federal Office of Topography, are often too detailed for this purpose. Therefore, GEOSTAT provides digital boundaries at different levels of generalisation. Using special algorithms, together with a manually supported and monitored optimisation process, the basic data with an original scale of 1:25,000 is simplified in such a way that it is suitable for maps and visualisations with a scale of 1:200,000 or smaller.
