In which method is digital photography utilized alongside computer software for measurement?

The most appropriate answer is that digital photography is utilized alongside computer software for measurement in photogrammetry. This method involves capturing images using digital cameras and applying software to analyze and extract geometric information from those images. Photogrammetry is fundamentally a technique that allows for the creation of maps, models, and measurements by interpreting photographs taken from various angles.

In contrast, orthophotography refers to aerial photographs that have been geometrically corrected to ensure scale uniformity, making them suitable for use as maps, but it is not primarily focused on measurement in the same way as photogrammetry. Stereophotogrammetry involves the use of two overlapping photographs to generate 3D information, but it is a specific subset of photogrammetry utilizing stereo images rather than simply digital photography. Laser scanning employs lasers to gather precise distance measurements and creates a point cloud but does not primarily rely on photography for measurement purposes. Thus, photogrammetry stands out in the context of merging photography with measurement techniques.
