We need to know in what scene each point in the shapefile belongs because scenes may overlap in space. With another column for 'training_set' we can immediately add predicted points in the shapefile to the training set (if we are confident there are no seals in the scene). We can use the latter to mine negative training samples that look like seals and add them to the training set.
