Create regression dataset (from continuous-valued raster layer and feature raster)

Create a regression dataset by sampling data for labeled pixels and store the result as a pickle file.

Usage:

  1. Open the algorithm from the processing toolbox.

  2. Select a continuous raster layer as well as a raster feature layer, e. g. your image, then click run.

    ../../../../_images/regraster.png

  3. The output classification dataset will be listed under Models in your Data Sources panel.

Parameters

Continuous-valued raster layer [raster]

Continuous-valued raster layer specifying sample locations and target data Y.If required, the layer is reprojected and resampled internally to match the feature raster grid.

Raster layer with features [raster]

Raster layer used for sampling feature data X.

Targets [band]

Bands with continuous-valued variables used as targets. An empty selection defaults to all bands in native order.

Exclude bad bands [boolean]

Whether to exclude bands, that are marked as bad bands, or contain no data, inf or nan values in all samples.

Default: True

Outputs

Output dataset [fileDestination]

Pickle file destination.
