So before supervised and unsupervised classification we need add band and then make band composite for your requirements then we will go for classification.
Supervised classification:
Supervised classification are those, which identify classes through image interpretation techniques and make signature file for Features.
Following are steps for supervised classification;
- So first we need image classification menu in ArcGIS software.
- Then we will go for training sample for your requirements.
- Then save signature file for making feature classes.
- Then apply maximum likelihood then done your classification then you need to change color for your requirement classes.
Unsupervised classification:
Unsupervised classification are those, which automatically identify classes nearly matching pixel value of image of specified number of classes.
Following steps for unsupervised classification;
- Direct apply iso-cluster unsupervised classification, then gives number of classes for your requirement what you need for your assignment or project.
- Then apply and ok.
