QGIS algorithm - Intersection (multiple)

Source: R/qgis_multiintersection.R

QGIS Algorithm provided by QGIS (native c++) Intersection (multiple) (native:multiintersection). This algorithm extracts the overlapping portions of features in the Input and all Overlay layers. Features in the output layer are assigned the attributes of the overlapping features from both the Input and Overlay layers. —————- Notes —————- - This algorithm drops existing primary keys or FID values and regenerates them in output layers.

qgis_multiintersection(
  INPUT = qgisprocess:::qgis_default_value(),
  OVERLAYS = qgisprocess:::qgis_default_value(),
  OVERLAY_FIELDS_PREFIX = 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.

OVERLAYS

multilayer - Overlay layers. .

OVERLAY_FIELDS_PREFIX

string - Overlay fields prefix. 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

sink - Intersection. 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.
