Supervised classification runs return error message with the following setting:
-SNAP v 7.0 with latest updates
-Landsat image using 6 TM bands (subset 3000x3000)
-7 Vector Data training areas are defined using the polygon tool
- In classifier dialog window, the Landsat image is added in ProductSet-Reader
- In classifier parameters window all is let as default. 7 training areas are listed and 6 TM bands are listed.
- Output filename is default
Error message: written in red in classifier window:
Same error with other supervised classifiers (KNN, Minimum Distance)
I tried saving file with vectors and reopen it as suggested in the forum. It returns the same error message.
Unsupervised approaches worked fine.
Thanks for helping.
