QGIS algorithm - Export mesh on grid

Description

QGIS Algorithm provided by QGIS (native c++) Export mesh on grid (native:exportmeshongrid). Exports mesh dataset values to a gridded point vector layer This algorithm exports a mesh layer's dataset values to a gridded point vector layer, with the dataset values on each point as attribute values. 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.

Usage

qgis_exportmeshongrid(
  INPUT = qgisprocess:::qgis_default_value(),
  DATASET_GROUPS = qgisprocess:::qgis_default_value(),
  DATASET_TIME = qgisprocess:::qgis_default_value(),
  EXTENT = qgisprocess:::qgis_default_value(),
  GRID_SPACING = qgisprocess:::qgis_default_value(),
  CRS_OUTPUT = qgisprocess:::qgis_default_value(),
  VECTOR_OPTION = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

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..

GRID_SPACING

distance - Grid spacing. 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..

VECTOR_OPTION

enum of ⁠("Cartesian (x,y)", "Polar (magnitude,degree)", "Cartesian and Polar")⁠ - Export vector option. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

OUTPUT

sink - Output vector layer. 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.
