Class Hierarchy

Base classes

QgsInterpolator

Interface class for interpolations.

Enums

TinInterpolation

Indicates the type of interpolation to be performed

Methods

setTriangulationSink

Sets the optional sink for saving the triangulation features.

Static Methods

triangulationFields

Returns the fields output by features when saving the triangulation.

class qgis.analysis.QgsTinInterpolator

Bases: QgsInterpolator

__init__(inputData: Iterable[QgsInterpolator.LayerData], interpolation: QgsTinInterpolator.TinInterpolation = QgsTinInterpolator.TinInterpolation.Linear, feedback: QgsFeedback | None = None)

Constructor for QgsTinInterpolator. The feedback object specifies an optional QgsFeedback object for progress reports and cancellation support. Ownership of feedback is not transferred and callers must ensure that it exists for the lifetime of this object.

Parameters:

• inputData (Iterable[QgsInterpolator.LayerData])

• interpolation (QgsTinInterpolator.TinInterpolation = QgsTinInterpolator.TinInterpolation.Linear)

• feedback (Optional[QgsFeedback] = None)

__init__(a0: QgsTinInterpolator)

Parameters:

a0 (QgsTinInterpolator)

class TinInterpolation(*values)

Bases: IntEnum

Indicates the type of interpolation to be performed

• Linear: Linear interpolation

• CloughTocher: Clough-Tocher interpolation

setTriangulationSink(self, sink: QgsFeatureSink | None)

Sets the optional sink for saving the triangulation features.

The sink must be setup to accept LineString features, with fields matching those returned by triangulationFields().

Parameters:

sink (Optional[QgsFeatureSink])

static triangulationFields() → QgsFields

Returns the fields output by features when saving the triangulation. These fields should be used when creating a suitable feature sink for setTriangulationSink()
