Arguments

INPUT

source - Point layer. Path to a vector layer.

Z_FIELD

field - Z value from field. The name of an existing field. ; delimited list of existing field names.

METRIC

enum of ⁠("Minimum", "Maximum", "Range", "Count", "Average distance", "Average distance between points")⁠ - Data metric to use. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

RADIUS_1

number - The first radius of search ellipse. 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.

RADIUS_2

number - The second radius of search ellipse. 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.

ANGLE

number - Angle of search ellipse rotation in degrees (counter clockwise). 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.

MIN_POINTS

number - Minimum number of data points to use. 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.

NODATA

number - NODATA marker to fill empty points. 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.

OPTIONS

string - Additional creation options. String 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.

EXTRA

string - Additional command-line parameters. String 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.

DATA_TYPE

enum of ⁠("Byte", "Int16", "UInt16", "UInt32", "Int32", "Float32", "Float64", "CInt16", "CInt32", "CFloat32", "CFloat64", "Int8")⁠ - Output data type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

OUTPUT

rasterDestination - Interpolated (data metrics). 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.
