The contour lines feature connects points of the same height with a polyline. Height values are extracted from a TIN (Triangular Irregular Network) or a DTM (Digital Terrain Model). This feature is also used to generate major and minor contour lines, which are visible in the images.
Note: To generate contour lines TIN or DTM needs to be generated in the project.
The following settings can be adjusted:
- Interval [units]: 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]: 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.
