qgis_tininterpolation: QGIS algorithm - TIN interpolation

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

QGIS algorithm - TIN interpolation

Description

QGIS Algorithm provided by QGIS TIN interpolation (qgis:tininterpolation). Generates a Triangulated Irregular Network (TIN) interpolation of a point vector layer. With the TIN method you can create a surface formed by triangles of nearest neighbor points. To do this, circumcircles around selected sample points are created and their intersections are connected to a network of non overlapping and as compact as possible triangles. The resulting surfaces are not smooth. The algorithm creates both the raster layer of the interpolated values and the vector line layer with the triangulation boundaries.

Usage

qgis_tininterpolation(
  INTERPOLATION_DATA = qgisprocess:::qgis_default_value(),
  METHOD = qgisprocess:::qgis_default_value(),
  EXTENT = qgisprocess:::qgis_default_value(),
  PIXEL_SIZE = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  TRIANGULATION = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INTERPOLATION_DATA	idw_interpolation_data - Input layer(s). .
METHOD	enum of ⁠("Linear", "Clough-Toucher (cubic)")⁠ - Interpolation method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
EXTENT	extent - Extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used..
PIXEL_SIZE	number - Output raster size. 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.
OUTPUT	rasterDestination - Interpolated. Path for new raster layer.
TRIANGULATION	sink - Triangulation. 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.
