I am trying to manually extract a set of ROIs in ENVI 5.0.
However, I can't seem to successfully line up the vector to be flush with the boundary of the pixels, which means I don't have fine-tune control over which pixels are included/excluded at the edge of my vector. Also, the resulting ROI ends up splicing pixels in half.
Is there anyway I can snap the vertices to the pixels when I'm drawing my vectors/ROIs?
