qgis_pointsalonglines: QGIS algorithm - Points along geometry

In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

QGIS algorithm - Points along geometry

Description

QGIS Algorithm provided by QGIS (native c++) Points along geometry (native:pointsalonglines). Creates regularly spaced points along line features. This algorithm creates a points layer, with points distributed along the lines of an input vector layer. The distance between points (measured along the line) is defined as a parameter. Start and end offset distances can be defined, so the first and last point will not fall exactly on the line's first and last nodes. These start and end offsets are defined as distances, measured along the line from the first and last nodes of the lines. —————- Notes —————- - This algorithm drops existing primary keys or FID values and regenerates them in output layers.

Usage

qgis_pointsalonglines(
  INPUT = qgisprocess:::qgis_default_value(),
  DISTANCE = qgisprocess:::qgis_default_value(),
  START_OFFSET = qgisprocess:::qgis_default_value(),
  END_OFFSET = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	source - Input layer. Path to a vector layer.
DISTANCE	distance - Distance. 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.
START_OFFSET	distance - Start offset. 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.
END_OFFSET	distance - End offset. 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.
OUTPUT	sink - Interpolated points. Path for new vector layer.
...	further parameters passed to qgisprocess::qgis_run_algorithm()
.complete_output	logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
.quiet	logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
.messages	logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
