Question

Which of the following is used to create 3D models?

• A. Panchromatic Imagery
• B. RGB Imagery
• C. Hyperspectral Imagery
• D. Digital Photogrammetry

Hint:

Remember: Digital Photogrammetry uses overlapping images to build 3D models.

Answer 1

The Correct Option is D

Digital Photogrammetry is the science of deriving accurate measurements from photographic data.
It is crucial for generating 3D models using overlapping aerial or satellite imagery.
By examining multiple images of the same location captured from various perspectives, photogrammetry facilitates the creation of precise digital elevation models (DEMs) and three-dimensional terrain representations.
While panchromatic, RGB, and hyperspectral imagery offer significant spectral information, they do not independently produce 3D models.
Therefore, Digital Photogrammetry (option D) is the correct method for generating 3D models.
