Classifiying a masked image

#1

Hi everyone,

I’m trying to class a Landsat image with some masks. First, I created a mask for greenhouses by specifying the range in band1 and a mask file appeared on Masked Manager. I clicked on the mask file in Mask Manager and see the masks on the image then performed Random Forest classification but it didn’t use the mask file, can anyone help?

I’m not sure, but I think the Random Forrest expects vector data and not a mask. So you can draw one or more polygons. A conversion from a mask to vector data is not possible at the moment.

Hi Falah,
actually it is not really related.
Random Forrest operator and computing the percentage of a mask is not really elated.
