Learning Module 6.1
Image Classification

Introduction

Land Class

In this module, we will cover image classification techniques. Image Classification is the process of grouping areas of an image into a number of classes or categories that represent similar features. The process produces "thematic maps" based on the original image or data. Unlike image interpretation, which is carried out by a human, the majority of these classification techniques are carried out by a computer. Image classification is used in many regional-scale projects and is often done to generate land cover data sets.
