I used Wayne County Landsat images. After spending some time experimenting with displaying different band combinations of Red, Green, and Blue values, including popular Landsat band combinations, I moved on to successfully display three bands simultaneusly. Below are my subset images of Wayne County. First my Unsupervised Classification:
After three tries I decided to give up on gettting all, or any, of my Supervised Clasification fields above 50%. I think the biggest problem with it is the roads in orange. Clearly there aren't huge chunks of roads like this. Surprisingly that field is the greatest percent reference accuracy. I think those orange road stripes across the water are cloud cover. But I think the urban area may be correct, as that is Detroit in the top right, and then further south Toledo. The vegetation could be correct to, but you would think there would be a lot more of it.
