LiDAR (Light Detection and Ranging) technology, originally developed in the 1960s for military applications such as detecting submarines from aircraft, has evolved into a powerful tool with a wide range…

The term LiDAR, which stands for Light Detection and Ranging, provides extremely precise, high-resolution 3D data. It is obtained from the ground or from the air using specialized sensors, and…

The technique of extracting information from satellite images is known as image categorization. Classifying every pixel in a digital image into one of several land use classes or themes is…

Classifying each pixel in a digital image into distinct land use/land cover classifications is the aim of image classification. There are two categories based on how the interpreter and computer…

picture or image enhancement is the process of making any part or feature of a picture more visible while hiding information in other parts or features. The statistical data regarding…

The Analytical Hierarchy Process (AHP) is a structured decision-making technique that facilitates criteria selection, prioritization, and systematic calculations to establish a hierarchy. It is particularly useful in complex decision-making scenarios…

It is stressed that land cover must be regarded as a geographically explicit feature that other disciplines may use as a geographical reference (e.g., for land use, climatic, and ecological…
