How to classify forest/land covers using Landsat imagery
Haruka3 replied to skylmla's topic in Remote Sensing
2 everybody. Anyone can answer me this problem? I use ENVI 4.8 to classify landuse. After did it, I want to evaluate the results but I don't have enought ground truth pixels, so I use "generating random sample" to take pixels (ENVI: Classification\Post Classification\Generating random sample\Using Ground truth roi) Random pixels appeared but they are the same location with training data. I think they must distribute over image and different place with training data. Anyone who met same problem, can answer me?. Thank you.
