QGIS algorithm - Create points layer from table

Description

QGIS Algorithm provided by QGIS (native c++) Create points layer from table (native:createpointslayerfromtable). This algorithm generates a points layer based on the values from an input table. The table must contain a field with the X coordinate of each point and another one with the Y coordinate, as well as optional fields with Z and M values. A CRS for the output layer has to be specified, and the coordinates in the table are assumed to be expressed in the units used by that CRS. The attributes table of the resulting layer will be the input table. —————- Notes —————- - This algorithm drops existing primary keys or FID values and regenerates them in output layers.

Usage

qgis_createpointslayerfromtable(
  INPUT = qgisprocess:::qgis_default_value(),
  XFIELD = qgisprocess:::qgis_default_value(),
  YFIELD = qgisprocess:::qgis_default_value(),
  ZFIELD = qgisprocess:::qgis_default_value(),
  MFIELD = qgisprocess:::qgis_default_value(),
  TARGET_CRS = 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.
XFIELD	field - X field. The name of an existing field. ; delimited list of existing field names.
YFIELD	field - Y field. The name of an existing field. ; delimited list of existing field names.
ZFIELD	field - Z field. The name of an existing field. ; delimited list of existing field names.
MFIELD	field - M field. The name of an existing field. ; delimited list of existing field names.
TARGET_CRS	crs - Target CRS. 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..
OUTPUT	sink - Points from table. 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.
