Question

For urban mapping requiring very detailed building footprints, the ideal satellite would provide _______.

• A. 30 m spatial resolution multispectral data
• B. 5 m spatial resolution panchromatic data
• C. 1 m or finer spatial resolution imagery
• D. 250 m spatial resolution MODIS data

Hint:

Urban mapping needs sub-meter to 1 m resolution for building-level accuracy.

Answer 1

The Correct Option is C

For detailed urban mapping, especially for building footprints, high spatial resolution is essential. Imagery with 1 m or finer resolution captures minute structural details crucial for accurate mapping.
