Low distortion area

During fieldwork in the official cadastral survey, a local adaptation must be made or proof must be provided that this is not needed. In low distortion areas, a local adaptation is not necessary, because the geometric accuracy complies with higher quality criteria. In practical applications, knowledge of low distortion areas makes working with satellite-based measuring methods easier, in particular with positioning services such as swipos.
