- Annually
- Maintenance note
-
The laser point data is updated in accordance with the TLM update cycle of 6 years. During this process, the dots are deleted and new points, breaklines and areas are set. For example, incorrect points in areas around bridges are removed and an enclosing breakline (enclosure) is implemented for lakes.
