Abstract: A method for processing scan data which are recorded by a measuring device with a scan functionality, wherein a reduced scan data record is created from a recorded scan data record with a first scan data density by selecting individual scan data points. Here, the selection represents an adaptation to a reduced scan data density, which is less than the first scan data density of the recorded scan data record. The reduced scan data density depends on a predetermined display resolution for displaying scan data. The reduced scan data record is transmitted to an external data processing device and displayed by the latter by means of a display, depending on the predetermined display resolution.

Abstract: Method for visually representing scanning data, which are composed of a multiplicity of individual measurement data. The individual measurement data in each case have at least one measurement value that is linked to a respective measurement direction, wherein the measurement directions are different from one another such that a predetermined scanning region with a predetermined scanning resolution is covered. The representation of the scanning data is effected by way of an image map with a number of map points that is dependent on a predetermined display resolution and by way of an assignment rule for assigning measurement value to map point, wherein the assignment is effected immediately on the basis of the respective measurement direction that is linked to the measurement value.
