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

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

Usage:

1. Open the algorithm from the processing toolbox.

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

   

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

Parameters

Continuous-valued vector layer [vector]

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

Raster layer with features [raster]

Raster layer used for sampling feature data X.

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

Fields with targets [field]

Fields used as target data y. If not selected, the fields defined by the renderer are used. If those are also not specified, an error is raised.

Outputs

Output dataset [fileDestination]

Pickle file destination.
