Explanation:
Detailed explanation-1: -Digital image classification is the process of assigning a pixel (or groups of pixels) of remote sensing image to a land cover class. The objective is to classify each pixel into only one class (crisp or hard classification) or to associate the pixel with many classes (fuzzy or soft classification).
Detailed explanation-2: -Geo-rectify image if it is not already done (UTM WGS 84) Run an unsupervised classification (you need to decide how many classes you want) Take output of the unsupervised classification and go out to the field with your GPS unit to define these classes. you can merge classes if they are the same.
