Create unsupervised dataset (from feature raster)

Create an unsupervised dataset by sampling data from valid pixels and store the result as a pickle file. A pixel is concidered valid, if the pixel profile is free of no data values, and not excluded by the (optionally) selected mask layer.

Parameters

Raster layer with features [raster]

Raster layer used for sampling feature data X.

Mask layer [layer]

A mask layer for limitting sample locations.

Sample size [number]

Approximate number of samples drawn from raster. If 0, whole raster will be used. Note that this is only a hint for limiting the number of rows and columns.

Default: 0

Outputs

Output dataset [fileDestination]

Pickle file destination.
