qgis_rastersampling: QGIS algorithm - Sample raster values

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

QGIS algorithm - Sample raster values

Description

QGIS Algorithm provided by QGIS (native c++) Sample raster values (native:rastersampling). Samples raster values under a set of points. This algorithm creates a new vector layer with the same attributes of the input layer and the raster values corresponding on the point location. If the raster layer has more than one band, all the band values are sampled.

Usage

qgis_rastersampling(
  INPUT = qgisprocess:::qgis_default_value(),
  RASTERCOPY = qgisprocess:::qgis_default_value(),
  COLUMN_PREFIX = 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.
RASTERCOPY	raster - Raster layer. Path to a raster layer.
COLUMN_PREFIX	string - Output column prefix. String 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 - Sampled. 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.
