QGIS algorithm - Export cross section dataset values on lines from mesh

Description

QGIS Algorithm provided by QGIS (native c++) Export cross section dataset values on lines from mesh (native:meshexportcrosssection). Extracts a mesh dataset's values from lines contained in a vector layer This algorithm extracts mesh's dataset values from line contained in a vector layer. Each line is discretized with a resolution distance parameter for extraction of values on its vertices.

Usage

qgis_meshexportcrosssection(
  INPUT = qgisprocess:::qgis_default_value(),
  DATASET_GROUPS = qgisprocess:::qgis_default_value(),
  DATASET_TIME = qgisprocess:::qgis_default_value(),
  INPUT_LINES = qgisprocess:::qgis_default_value(),
  RESOLUTION = qgisprocess:::qgis_default_value(),
  COORDINATES_DIGITS = qgisprocess:::qgis_default_value(),
  DATASET_DIGITS = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	mesh - Input mesh layer. Path to a mesh layer.
DATASET_GROUPS	meshdatasetgroups - Dataset groups. .
DATASET_TIME	meshdatasettime - Dataset time. .
INPUT_LINES	source - Lines for data export. Path to a vector layer.
RESOLUTION	distance - Line segmentation resolution. 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.
COORDINATES_DIGITS	number - Digits count for coordinates. 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.
DATASET_DIGITS	number - Digits count for dataset value. 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	fileDestination - Exported data CSV file. Path for new file.
...	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.
