QGIS Algorithm provided by QGIS (native c++) Hillshade (native:hillshade). This algorithm calculates the hillshade of the Digital Terrain Model in input. The shading of the layer is calculated according to the sun position (azimuth and elevation).

qgis_hillshade(
  INPUT = qgisprocess:::qgis_default_value(),
  Z_FACTOR = qgisprocess:::qgis_default_value(),
  AZIMUTH = qgisprocess:::qgis_default_value(),
  V_ANGLE = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT

raster - Elevation layer. Path to a raster layer.

Z_FACTOR

number - Z factor. 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.

AZIMUTH

number - Azimuth (horizontal angle). 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.

V_ANGLE

number - Vertical angle. 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

rasterDestination - Hillshade. Path for new raster 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.
