QGIS algorithm - Geodesic line split at antimeridian

Description

QGIS Algorithm provided by QGIS (native c++) Geodesic line split at antimeridian (native:antimeridiansplit). Splits lines into multiple geodesic segments when the line crosses the antimeridian (±180 degrees longitude). This algorithm splits a line into multiple geodesic segments, whenever the line crosses the antimeridian (±180 degrees longitude). Splitting at the antimeridian helps the visual display of the lines in some projections. The returned geometry will always be a multi-part geometry. Whenever line segments in the input geometry cross the antimeridian, they will be split into two segments, with the latitude of the breakpoint being determined using a geodesic line connecting the points either side of this segment. The current project ellipsoid setting will be used when calculating this breakpoint. If the input geometry contains M or Z values, these will be linearly interpolated for the new vertices created at the antimeridian.

Usage

qgis_antimeridiansplit(
  INPUT = 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.
OUTPUT	sink - Split. 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.
