Description

QGIS Algorithm provided by SAGA Next Gen Line smoothing (sagang:linesmoothing). —————- Arguments —————- LINES_IN: Lines Argument type: source Acceptable values: - Path to a vector layer LINES_OUT: Smoothed Lines Argument type: vectorDestination Acceptable values: - Path for new vector layer METHOD: Method Default value: 2 Argument type: enum Available values: - 0: (0) basic SIA model - 1: (1) improved SIA model - 2: (2) Gaussian Filtering Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' SENSITIVITY: Sensitivity Default value: 3 Argument type: number Acceptable values: - 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 ITERATIONS: Iterations Default value: 10 Argument type: number Acceptable values: - 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 PRESERVATION: Preservation Default value: 10 Argument type: number Acceptable values: - 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 SIGMA: Sigma Default value: 2 Argument type: number Acceptable values: - 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

Usage

sagang_linesmoothing(
  LINES_IN = qgisprocess:::qgis_default_value(),
  LINES_OUT = qgisprocess:::qgis_default_value(),
  METHOD = qgisprocess:::qgis_default_value(),
  SENSITIVITY = qgisprocess:::qgis_default_value(),
  ITERATIONS = qgisprocess:::qgis_default_value(),
  PRESERVATION = qgisprocess:::qgis_default_value(),
  SIGMA = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

LINES_IN	source - Lines. Path to a vector layer.
LINES_OUT	vectorDestination - Smoothed Lines. Path for new vector layer.
METHOD	enum of ⁠("(0) basic SIA model", "(1) improved SIA model", "(2) Gaussian Filtering")⁠ - Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
SENSITIVITY	number - Sensitivity. 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.
ITERATIONS	number - Iterations. 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.
PRESERVATION	number - Preservation. 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.
SIGMA	number - Sigma. 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.
...	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.
