Sensors capture light or heat reflected from Earth’s surface. This data is processed into images for analysis.
Active sensors (like radar) emit their own energy, while passive sensors (like cameras) rely on sunlight. Both provide unique data insights.
Landsat, Sentinel, and ISRO’s CARTOSAT capture high-resolution Earth images. They track climate, forests, and urban expansion.
Drones provide detailed, real-time land surveys. Used in farming, construction, and wildlife monitoring.
Farmers use it to monitor crop health and soil moisture. Helps in precision farming for better yields.
Detects floods, wildfires, and earthquakes quickly. Aids in rescue operations and damage assessment.
Tracks city growth, infrastructure, and pollution. Helps design sustainable urban spaces.
Monitors deforestation, glaciers, and ocean health. Essential for fighting climate change.
Used for surveillance, border security, and terrain mapping. Enhances military strategy and safety.
GIS analyzes remote sensing data for better decision-making. Used in maps, navigation, and research.
AI and machine learning improve data analysis. Hyperspectral sensors and real-time monitoring are rising trends.
Jobs in geospatial analysis, environmental science, and satellite tech. High demand in IT and research fields.
