Hello, everyone I am a junior user of ENVI programming, I try to transter a raster image to a vector file. The Raster to Vector function in ENVI only can transfer specified DN value to a vector file. I want use batch processing to transfer the whole image to a vector file in which different DN values are in different layers. But I can not find a suitale ENVI routine to realize the tranformation in ENVI programming, how can I realize this? Many thanks!
