The Contour lines feature connects points of the same height with a polyline. The height values are extracted from the TIN (Triangular Irregular Network). Major and minor contour lines which are projected also onto the images are generated with this feature.
The following setting can be adjusted:
- Interval [units]: It defines the contour line elevation interval. It can be in meters or in imperial according to the coordinate system used:
- 1 m - default.
- 3 ft(US) - default.
- Discard contour loops shorter than [units]: It detects and discards contour lines with shorter length. It can be in meters or in imperial according to the coordinate system used:
- 10 m - default.
- 30 ft(US) - default.
