The task described is about using photos to identify and classify what is seen—recognizing objects and mapping their environmental characteristics like soil types, vegetation, and rock types. This relies on interpreting the imagery: looking at color, tone, texture, shape, pattern, and the context of features to assign them to semantic categories and create thematic maps. That approach is interpretive photogrammetry, also known as photo-interpretation, which focuses on analyzing photographs to derive qualitative information and map distribution of environmental factors. The other areas emphasize measurement and geometry (aerial or metric photogrammetry) or are unrelated (extraterrestrial photographs), rather than the classification and mapping of land-cover features.
