Question 1

What is Remote Sensing GIS and why is it important?

Accepted Answer

Remote Sensing GIS combines satellite or aerial imagery with Geographic Information Systems to analyze Earth’s surface. It is vital for monitoring environmental changes, managing resources, planning urban development, and responding to disasters.

Question 2

How has AI changed Remote Sensing GIS?

Accepted Answer

AI automates feature extraction, change detection, and predictive modeling in Remote Sensing GIS. Machine learning models can process massive satellite datasets quickly, improving accuracy in applications like crop classification, deforestation tracking, and disaster assessment.

Question 3

Which satellites are most commonly used for Remote Sensing GIS today?

Accepted Answer

Landsat (NASA/USGS), Sentinel‑2 (ESA), PlanetScope (Planet Labs), and high‑resolution commercial satellites like WorldView‑3 and GeoEye‑1 are frequently used. Radar missions such as Sentinel‑1 provide all‑weather, day‑night imaging capability.
