  • Remote sensing , in modern usage, generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans) by means of propagated signals. Remote sensing makes it possible to collect data on dangerous or inaccessible areas. Remote sensing also replaces costly and slow data collection on the ground, ensuring in the process that areas or objects are not disturbed. Remote sensing data is collected by satellite, aircraft, spacecraft, buoy, ship, and helicopter. Such data can be used to understand and analyze geology, mineralisation, vegetation, erosion, pollution, forestry, weather and land use. These things can be mapped, imaged, tracked and observed. The process of remote sensing is also helpful for city planning, public health, archaeological investigations, disease mapping, military observation and geomorphological surveying.
  • Geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data.  This is a system that brings together the disciplines of cartography, statistical analysis, and database technology on a common platform in such a flexible mode that all future modifications, corrections can be made easily. Modern GIS technologies use digital information, for which various digitized data creation methods are used. The most common method of data creation is digitization, where a hard copy map or survey plan is transferred into a digital medium through the use of a CAD program, and geo-referencing capabilities. With the wide availability of ortho-rectified imagery (both from satellite and aerial sources), heads-up digitizing is becoming the main avenue through which geographic data is extracted.                                                                                                                                                                                                                                                                        GIS lets us visualize, question, analyze, interpret, and understand data to reveal relationships, patterns, and trends.
  • Geology is the science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geological understanding and knowledge is a must for mineral exploration, mining, hydroelectrical projects, large scale engineering projects and so on. Remote sensing, Geochemical, Geophysical and other kinds of data can be integrated using GIS and then interpreted and analysed for a meaningful result for decision making only with the help of geological knowledge. 
  • Remote sensing has become a widely accepted research and exploration tool by almost all Geological Surveys the world over. Remote sensing is often combined with other data sources providing complementary measurements. Remote sensing is not limited to direct geology applications - it is also used to support logistics, such as route planning for access into a mining area, reclamation monitoring, and generating base-maps upon which geological data can be referenced or superimposed.
  • Geological applications of remote sensing include lithological mapping, structural mapping, Alteration zone mapping, mineral exploration (Potential zone mapping), hydrocarbon exploration, environmental geology, geobotany, baseline infrastructure, sedimentation mapping and monitoring, event mapping and monitoring, geo-hazard mapping and planetary mapping.
  • GIS softwares can be used for geo-referencing and digitising maps, plotting data points, drawing contours and elevation maps, integration of various data, thematic maps and images such as Geochemical, geophysical, geological, cadastral, topographical, sampling etc.
  •  Understanding ground water table depth, groundwater gradient, flow directions, drainage patterns etc are very essential in watershed management and groundwater potential mapping. Understanding aquifers is also very important for large scale engineering and mineral exploration projects.
