Remote Sensing application in modern Mineral exploration

I. Introduction

A. Definition of Remote Sensing

Satellite Orbiting the Earth

Remote sensing is the science of obtaining information about objects or areas without physically visiting them. Through advanced technologies like satellite imagery and hyperspectral imaging, we can capture detailed data from Earth's surface. This technology allows for the identification of geological formations, rock types, and structural features across vast areas. Remote sensing can be performed from terrestrial platforms or from space via satellite imagery, providing both geostationary and orbital perspectives. It has a wide range of applications, from geology and mineral exploration to agriculture, hydrology, and meteorology.

B. Importance of Mineral Exploration

Mineral exploration, underpinned by remote sensing techniques, is critical in today's modern world. It provides raw materials for various industries and plays a pivotal role in a nation's wealth and prosperity. With the rise in demand for minerals in industries like steel, automotive, and electronics, the mineral exploration sector is experiencing steady growth.
