Fundamentals of Remote Sensing

Remote Sensing (RS)

• Remote Sensing involves acquiring information about objects without direct physical contact.
• It utilizes measurements of electromagnetic energy emitted or reflected from the Earth's surface or atmosphere.

What is Remote Sensing

• Satellite remote sensing combines understanding, interpretation, and relations between natural phenomena and electromagnetic measurements.
• Sensors onboard satellites capture data from various Earth locations, outputting imagery for analysis.

Process of Remote Sensing

• The process includes planning, data acquisition, processing, and analysis, often using tools like digitizers and scanners.
• Techniques such as photogrammetry and GIS (Geographic Information Systems) integrate various data types for enhanced analysis.

Satellite Systems in Remote Sensing

• Earth Observation Satellites help monitor environmental and land-use changes, providing crucial data.
• Communication Satellites facilitate data transmission and communication links required for remote sensing applications.

Needs for Spatial Data

• Spatial data is essential for accurate mapping, monitoring changes, and supporting various applications in environmental science, agriculture, and urban planning.

Advantages of Remote Sensing

• Offers a wide spatial coverage, enabling the collection of data over large areas in a cost-effective manner.
• Provides timely and repeatable data collection, essential for studying dynamic environmental processes.

Applications of Remote Sensing

• Widely used in agriculture for crop monitoring, yield prediction, and land-use planning.
• Applied in disaster management for damage assessment and response planning after events like floods or earthquakes.
