Which term relates to measurements taken from aerial photographs to quantify Earth's surface features?

• A. Aerial Photogrammetry
• B. Metric Photogrammetry
• C. Interpretative Photogrammetry
• D. Terrestrial Photogrammetry

Answer: (B)

The key idea is measuring from aerial imagery with precision. That capability is described by metric photogrammetry, which focuses on turning aerial photographs into quantitative data—accurate distances, areas, elevations, and volumes—through calibrated cameras, stereo models, and ground control to establish scale. Aerial photogrammetry is the broad field of collecting measurements from air photos, but metric photogrammetry specifically emphasizes the exact measurements needed to quantify Earth's features. Interpretative photogrammetry deals with identifying and describing features rather than measuring them, and terrestrial photogrammetry uses ground-based photos rather than aerial ones. So for converting aerial photos into precise, numerical measurements of the surface, metric photogrammetry is the right term.
