sagang_surfaceandgradient: QGIS algorithm - Surface and gradient

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

QGIS algorithm - Surface and gradient

Description

QGIS Algorithm provided by SAGA Next Gen Surface and gradient (sagang:surfaceandgradient). —————- Arguments —————- MASK: Mask Argument type: raster Acceptable values: - Path to a raster layer SURF: Surface Argument type: rasterDestination Acceptable values: - Path for new raster layer GRAD: Gradient Argument type: rasterDestination Acceptable values: - Path for new raster layer SURF_E: Surface Approximation Threshold Default value: 0.001 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_surfaceandgradient(
  MASK = qgisprocess:::qgis_default_value(),
  SURF = qgisprocess:::qgis_default_value(),
  GRAD = qgisprocess:::qgis_default_value(),
  SURF_E = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

MASK	raster - Mask. Path to a raster layer.
SURF	rasterDestination - Surface. Path for new raster layer.
GRAD	rasterDestination - Gradient. Path for new raster layer.
SURF_E	number - Surface Approximation Threshold. 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.
