QGIS algorithm Dissolve

Description

QGIS Algorithm provided by GDAL Dissolve (gdal:dissolve)

Usage

gdal_dissolve(
  INPUT = qgisprocess::qgis_default_value(),
  FIELD = qgisprocess::qgis_default_value(),
  GEOMETRY = qgisprocess::qgis_default_value(),
  EXPLODE_COLLECTIONS = qgisprocess::qgis_default_value(),
  KEEP_ATTRIBUTES = qgisprocess::qgis_default_value(),
  COUNT_FEATURES = qgisprocess::qgis_default_value(),
  COMPUTE_AREA = qgisprocess::qgis_default_value(),
  COMPUTE_STATISTICS = qgisprocess::qgis_default_value(),
  STATISTICS_ATTRIBUTE = qgisprocess::qgis_default_value(),
  OPTIONS = 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.
FIELD	field - Dissolve field. The name of an existing field. ; delimited list of existing field names.
GEOMETRY	string - Geometry column name. String value.
EXPLODE_COLLECTIONS	boolean - Produce one feature for each geometry in any kind of geometry collection in the source file. 1 for true/yes. 0 for false/no.
KEEP_ATTRIBUTES	boolean - Keep input attributes. 1 for true/yes. 0 for false/no.
COUNT_FEATURES	boolean - Count dissolved features. 1 for true/yes. 0 for false/no.
COMPUTE_AREA	boolean - Compute area and perimeter of dissolved features. 1 for true/yes. 0 for false/no.
COMPUTE_STATISTICS	boolean - Compute min/max/sum/mean for attribute. 1 for true/yes. 0 for false/no.
STATISTICS_ATTRIBUTE	field - Numeric attribute to calculate statistics on. The name of an existing field. ; delimited list of existing field names.
OPTIONS	string - Additional creation options. String value.
OUTPUT	vectorDestination - Dissolved. 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.
