QGIS algorithm - B-spline approximation

Source: R/sagang_bsplineapproximation.R

QGIS Algorithm provided by SAGA Next Gen B-spline approximation (sagang:bsplineapproximation). —————- Arguments —————- SHAPES: Points Argument type: source Acceptable values: - Path to a vector layer FIELD: Attribute Argument type: field Acceptable values: - The name of an existing field - ; delimited list of existing field names TARGET_USER_XMIN TARGET_USER_XMAX TARGET_USER_YMIN TARGET_USER_YMAX: Output extent (optional) Argument type: extent Acceptable values: - 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.

Arguments

SHAPES

source - Points. Path to a vector layer.

FIELD

field - Attribute. The name of an existing field. ; delimited list of existing field names.

TARGET_USER_XMIN_TARGET_USER_XMAX_TARGET_USER_YMIN_TARGET_USER_YMAX

extent - Output 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.. Original algorithm parameter name: TARGET_USER_XMIN TARGET_USER_XMAX TARGET_USER_YMIN TARGET_USER_YMAX.

TARGET_USER_SIZE

number - Cellsize. 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.

TARGET_OUT_GRID

rasterDestination - Target Grid. Path for new raster layer.

LEVEL

number - Range. 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.

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.
