Contour lines

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.

Access:

Click Process or,
On the Menu bar, click Process > Contour lines.

Note: To generate contour lines the TIN 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.

Example: Contour lines generated from terrain points of the PIX4Dsurvey example dataset.
