* what is classification:

IClassification system are used to categorize the pixels in the satellite data for differentiating the various earth features such as barren land, forests, roads, settlements, water bodies, rocks based on the spectral reflectance. This technique is highly used to generate the LULC (Land Use Land Cover Map).

There are three techniques to classify the image:

1. Supervised Classification

2. Unsupervised classification


* What is supervised classification:

In simple word, supervised learning algorithms are trained using labeled data, meaning the input data points are associated with corresponding output labels. During training, the algorithm learns to map input features to specific target classes, allowing it to make prediction on new. The goal of supervised classification is to accurately classify new instances into predefinedcatagories or classes.
