We use point heights from a survey to generate a TIN. In order to improve the quality of the TIN, additional break lines should be defined.
These break lines shall receive the height information from the point heights, where intermediate values of the vertices shall be interpolated.
How can these steps be achieved with QGIS:
- Taking the height from the points at the start or end point of a line
- Interpolation of the height for the vertices in between
