photogrammetrisesti

Photogrammetrisesti is an adverb in Finnish used to describe actions, measurements, or analyses that are carried out using photogrammetry. The term indicates that the procedure or result derives from photogrammetric methods rather than from direct measurement or other sensing techniques.

Photogrammetry is the science of obtaining reliable measurements from photographs, typically from overlapping imagery captured from aerial or terrestrial platforms. The photogrammetrisesti conducted workflow generally includes image acquisition, camera calibration and image orientation, then 3D reconstruction by dense matching or feature-based methods, followed by the production of georeferenced products such as point clouds, digital elevation models, orthophotos, and textured 3D models.

Common applications include topographic mapping, urban planning, architecture, archaeology, forestry, and disaster response. The term photogrammetrisesti is often used in Finnish-language reporting and documentation to distinguish photogrammetric data and analyses from those obtained by lidar, laser scanning, or manual survey.

Advantages of photogrammetrist-based approaches are non-contact data collection, high spatial resolution with dense 3D information, and relatively lower sensor costs when using regular cameras. Limitations include dependence on image texture and lighting, potential errors due to occlusions and distortions, and the need for ground control or accurate georeferencing for precise measurements.

Notes: The word combines photogrammetry with the Finnish adverbial suffix -isesti. It is mainly encountered in Finnish sources and is rarely used outside Finnish-language contexts.
