[GRASS-user] Semi-automatic classification with GRASS modules

[Michele Zurlo]

Hi Giuseppe try to take a look also here, if you find something that can help you

I tried a combination of i.segment.uspo, i.segment and v.class.mlR (Grippa et al. 2017) to classify an aerial images of Alpine areas. I get low a accuracy in classification because I did the great mistake of no consider the single properties of habitat in different Alpine belts. I hope you will get better result ;-)


I use this e-mail also to make a question, during a work I tried to classify a pancromatic aerial image using an unsupervised approach. Running i.cluster it gave me an error indicating that it needs more than two classes. What I missed? 

 
Thank you 


Michele
