Digital Image Processing (DIP) is performed using sophisticated computer algorithms on satellite’s raw imagery. The main processes are as image rectification and restoration i.e. geometric and radiometric corrections; image enhancement i.e. effective display for interpretation; and geospatial information extraction using digital classification and thematic geovisualisation. In other words, satellite’s digital imagery requires algorithmic processing to achieve better outcome in real time for real world. The usage of specific algorithms depends on individual’s goals for specific purpose. So, digital processing of imagery is based on complex algorithms processed in high-end sophisticated processor for simple tangible tasks. As a result, processed remote sensing satellite imagery have been more popularity in earth’s resources exploration and management for sustainable regional development.
