qgis_coveragevalidate: QGIS algorithm - Validate coverage

In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

QGIS algorithm - Validate coverage

Description

QGIS Algorithm provided by QGIS (native c++) Validate coverage (native:coveragevalidate). Analyzes a coverage of polygon features to find places where the assumption of exactly matching edges is not met This algorithm analyzes a coverage (represented as a set of polygon features with exactly matching edge geometry) to find places where the assumption of exactly matching edges is not met. Invalidity includes polygons that overlap or that have gaps smaller than the specified gap width.

Usage

qgis_coveragevalidate(
  INPUT = qgisprocess:::qgis_default_value(),
  GAP_WIDTH = qgisprocess:::qgis_default_value(),
  INVALID_EDGES = 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.
GAP_WIDTH	distance - Gap width. 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.
INVALID_EDGES	sink - Invalid edges. 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.
