Hi, If you want to produce a single classification map which takes into account the temporal dynamics of your landscape, you should stack all the images into a single one and use a single vector file as reference. If you want to have a classifier which can be applied to a single image, but you want it to be trained to take into account the diversity in the different images, you should use 4 input images and the corresponding 4 vector files. >From your initial message, I think you want to do the first task.
