Low-budget topographic surveying comes of age: Structure from motion photogrammetry in geography and the geosciences.

An editorial is presented which discusses article related to photogrammetry in geography and the geosciences. Topics discussed include photogrammetry, a technique by which volumetric information describing surface structures; Structure from motion (FM) photogrammetry uses advances in computer vision algorithms; and conclude by evidencing the various ways in which SfM photogrammetric methods offer other advantages over terrestrial laser scanning for such applications.
