QGIS algorithm - Self-contacts — qgis_checkgeometryselfcontact • qgis

QGIS Algorithm provided by QGIS (native c++) Self-contacts (native:checkgeometryselfcontact). Detects self contact points in the geometry (line or polygon). This algorithm checks if the geometry has self contact points (in line or polygon). Self contacts are errors.

  INPUT = qgisprocess:::qgis_default_value(),
  UNIQUE_ID = qgisprocess:::qgis_default_value(),
  ERRORS = qgisprocess:::qgis_default_value(),

)

Arguments

INPUT: source - Input layer. Path to a vector layer.
UNIQUE_ID: field - Unique feature identifier. The name of an existing field. ; delimited list of existing field names.
ERRORS: sink - Self contact error points. Path for new vector layer.
OUTPUT: sink - Self contact features. Path for new vector layer.
TOLERANCE: number - Tolerance. 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.
...: 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.
