QGIS algorithm - Rasterize mesh dataset

Source: R/qgis_meshrasterize.R

QGIS Algorithm provided by QGIS (native c++) Rasterize mesh dataset (native:meshrasterize). Creates a raster layer from a mesh dataset This algorithm creates a raster layer from a mesh dataset. For data on volume (3D stacked dataset values), the exported dataset values are averaged on faces using the method defined in the mesh layer properties (default is Multi level averaging method). 1D meshes are not supported.

Arguments

INPUT

mesh - Input mesh layer. Path to a mesh layer.

DATASET_GROUPS

meshdatasetgroups - Dataset groups. .

DATASET_TIME

meshdatasettime - Dataset time. .

EXTENT

extent - Extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used..

PIXEL_SIZE

distance - Pixel size. 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.

CRS_OUTPUT

crs - Output coordinate system. CRS as an auth ID (e.g. 'EPSG:3111'). CRS as a PROJ4 string (e.g. 'PROJ4:…'). CRS as a WKT string (e.g. 'WKT:…'). Path to a layer. The CRS of the layer is used..

CREATE_OPTIONS

string - Creation options. 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

rasterDestination - Output raster layer. 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.
