30000 0 Posted May 12, 2014 Report Share Posted May 12, 2014 Hi, I'm trying to perform some wetland supervised classification, and I am getting quite a bit of spectral confusion, with overlapping and incorrect classes. I am using ERDAS 2014 and Landsat 8 imagery. When evaluating the training classes, some of the bands show quite distinct and separate histograms, while in other bands the histograms interfere with each other. Is there a way to only use some of the bands to classify certain training sites? The only way I have seen so far is to create a subset image without certain bands. However, that requires a whole new training signature file to be made. Is there a quicker way? Thanks Quote Link to post Share on other sites
msig0000 357 Posted June 26, 2014 Report Share Posted June 26, 2014 Hi, There r many solution but easiest one could be -you use ENVI where u can select the band(s) will participate in the supervised class...I m not ENVI affiliated nor advertising... Quote Link to post Share on other sites
am2 90 Posted June 26, 2014 Report Share Posted June 26, 2014 In Envi you can creat ROI's and save them when you have a new set of layers you can add roi to it and classify them Quote Link to post Share on other sites
