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

QGIS algorithm - Raster proximity buffer

Description

QGIS Algorithm provided by SAGA Next Gen Raster proximity buffer (sagang:rasterproximitybuffer). —————- Arguments —————- SOURCE: Source Grid Argument type: raster Acceptable values: - Path to a raster layer DISTANCE: Distance Grid Argument type: rasterDestination Acceptable values: - Path for new raster layer ALLOC: Allocation Grid Argument type: rasterDestination Acceptable values: - Path for new raster layer BUFFER: Buffer Grid Argument type: rasterDestination Acceptable values: - Path for new raster layer DIST: Buffer distance Default value: 500 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 IVAL: Equidistance Default value: 100 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_rasterproximitybuffer(
  SOURCE = qgisprocess:::qgis_default_value(),
  DISTANCE = qgisprocess:::qgis_default_value(),
  ALLOC = qgisprocess:::qgis_default_value(),
  BUFFER = qgisprocess:::qgis_default_value(),
  DIST = qgisprocess:::qgis_default_value(),
  IVAL = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

SOURCE	raster - Source Grid. Path to a raster layer.
DISTANCE	rasterDestination - Distance Grid. Path for new raster layer.
ALLOC	rasterDestination - Allocation Grid. Path for new raster layer.
BUFFER	rasterDestination - Buffer Grid. Path for new raster layer.
DIST	number - Buffer 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.
IVAL	number - Equidistance. 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.
