QGIS Algorithm provided by QGIS IDW interpolation (qgis:idwinterpolation). Generates an Inverse Distance Weighted (IDW) interpolation of a point vector layer. Sample points are weighted during interpolation such that the influence of one point relative to another declines with distance from the unknown point you want to create.

Arguments

INTERPOLATION_DATA

idw_interpolation_data - Input layer(s). .

DISTANCE_COEFFICIENT

number - Distance coefficient P. 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.

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.

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.
