Which technique is used for the study of land use pattern?

Correct option is D

The correct answer is: (d) Satellite imaging, GIS and GPS

Explanation:

• The study of land use patterns involves identifying how land is being utilized (e.g., agriculture, urban, forest).

• Satellite imaging provides large-scale and up-to-date images of Earth’s surface, helping in visualizing different land types.

• GIS (Geographic Information System) is used to store, analyze, and interpret spatial data collected from satellites.

• GPS (Global Positioning System) aids in accurate ground verification and mapping locations on the Earth.

• Together, these three technologies provide a comprehensive toolset for land use and land cover studies, allowing for data collection, spatial analysis, and monitoring over time.

• Satellite imaging helps in capturing remote sensing data to classify land types.

• GIS integrates spatial and attribute data to generate land use maps and zoning plans.

• GPS enhances ground-truthing, ensuring accuracy in classification and mapping.

• These tools are essential for urban planning, agricultural monitoring, deforestation tracking, and disaster management.

• Organizations like ISRO, NRSC, and NASA use these technologies extensively.

• India’s Bhuvan Portal (by ISRO) uses these tools for land resource mapping.

• (a) Aerial photography: Earlier method using aircraft; provides limited coverage and is less efficient than satellite-based methods.

• (b) Satellite imaging: Alone it gives images but lacks analytical tools (GIS) and location accuracy (GPS).

• (c) Satellite imaging and GIS: Better, but without GPS, lacks ground accuracy verification.
