Class: QgsRelief¶

Produces colored relief rasters from DEM.

Methods

`addReliefColorClass`
`calculateOptimizedReliefClasses`	Calculates class breaks according with the method of Buenzli (2011) using an iterative algorithm for segmented regression
`clearReliefColors`
`exportFrequencyDistributionToCsv`	Write frequency of elevation values to file for manual inspection
`processRaster`	Starts the calculation, reads from mInputFile and stores the result in mOutputFile
`reliefColors`
`setReliefColors`
`setZFactor`
`zFactor`

addReliefColorClass(self, color: QgsRelief.ReliefColor)[source]¶

calculateOptimizedReliefClasses(self) → List[QgsRelief.ReliefColor]¶

Calculates class breaks according with the method of Buenzli (2011) using an iterative algorithm for segmented regression

exportFrequencyDistributionToCsv(self, file: str | None) → bool[source]¶

Write frequency of elevation values to file for manual inspection

processRaster(self, feedback: QgsFeedback | None = None) → int[source]¶

Starts the calculation, reads from mInputFile and stores the result in mOutputFile

Parameters:: feedback (Optional[QgsFeedback] = None) – feedback object that receives update and that is checked for cancellation.
Return type:: int
Returns:: 0 in case of success
