GNSS – low distortion areas

This dataset provides information about the locations of low distortion areas, i.e. areas with a high degree of geometric precision.

Product description

This dataset depicts those areas in Switzerland whose geometric precision meets higher quality criteria (referred to as «low distortion areas»). In these areas, practical work with satellite-based measurement methods – in particular, positioning services – is simplified because no local adjustments need to be made.

Status of data

This dataset is updated and published annually.


This dataset is available free of charge.

Procurement of data

The data are available in four formats. For further information, please refer to the product information.
