Question

............. photography involves taking a photograph from two eye positions.

Hint:

Stereoscopic pairs give depth to flat images, making terrain features easy to measure.

Answer 1

Stereoscopic photography is a technique in photogrammetry where overlapping photographs are taken from two slightly different positions, imitating human binocular vision.
When these images are viewed together through a stereoscope or software, they create a three-dimensional (3D) perspective of the terrain.
This method is widely used in topographic mapping, forestry, urban planning, and geological studies to measure elevation differences and detect surface features accurately.
Stereoscopic images allow interpreters to visualize depth, slope, and landform variations which are not easily visible in single photographs.
This depth perception greatly enhances the precision of map-making and terrain modeling.
Hence, the blank is correctly filled with Stereoscopic.
