qgis_randompointsalongline.Rd
QGIS Algorithm provided by QGIS Random points along line (qgis:randompointsalongline). This algorithm creates a point layer with a given "Number of points" placed on the lines of the "Input layer". The location of each point is determined by randomly selecting a feature, then a segment of the line geometry of that feature, and finally a random position on that segment. A minimum distance between the points can be specified (Euclidean distance). —————- Notes —————- - This algorithm drops existing primary keys or FID values and regenerates them in output layers.

source
- Input layer. Path to a vector layer.
number
- Number of points. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
distance
- Minimum distance between points. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
sink
- Random points. Path for new vector layer.
further parameters passed to qgisprocess::qgis_run_algorithm()
logical specifying if complete out of qgisprocess::qgis_run_algorithm()

). Default value is TRUE
.
logical specifying if parameter .quiet
for qgisprocess::qgis_run_algorithm()
Default value is TRUE
.
logical specifying if messages from qgisprocess::qgis_run_algorithm()
should be printed (TRUE
) or not (FALSE
). Default value is FALSE
.
