Photogrammetry Principles Mastery Hub: The Industry Foundati

Within the context of "The Complete Aerial Photogrammetry Course 2026," which of the following sensor types, when used for aerial photogrammetry, is most susceptible to geometric distortions introduced by the Earth's curvature at very high altitudes, necessitating advanced georeferencing techniques beyond simple planar approximations?

According to "The Complete Aerial Photogrammetry Course 2026," when discussing the fundamental principles of aerial triangulation, what is the primary implication of a low "ground sample distance" (GSD) on the accuracy of the resulting 3D model, assuming all other parameters are ideal?

asks about the *implication* on accuracy of the *resulting 3D model*. A very low GSD, while capturing fine detail, can amplify noise and small errors in the imagery, leading to a less precise and potentially less accurate overall 3D model if not handled carefully. The other options describe related concepts but not the primary accuracy implication of a low GSD on the 3D model itself. High redundancy (
