The Contour lines feature connects points of the same height with a polyline. The height values are extracted from the TIN (Triangular Irregular Network) or DTM (Digital Terrain Model). Major and minor contour lines, which are projected also onto the images are generated with this feature.
Note: To generate contour lines the TIN or DTM needs to be generated in the project.
The following settings 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.
Tip: The minimum interval value supported is 0.1. Values below this threshold are not valid and will not be accepted.
- 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.
