He applied the technique of plane table photogrammetry in addition to a conventional geodetic survey, assisted by the novel lightweight, accurate phototheodolite that he had developed for high-mountain applications.
It encompasses education on theories and practices in disciplines of geodesy, geo-physics, photogrammetry, land surveying, cartography and reprography.
In addition to damage to structures and vegetation, radar data, photogrammetry, and cycloidal marks (ground swirl patterns) may be utilized when available.
Camera matching, photogrammetry, and photo rectification techniques are used to create three-dimensional and top-down views from the two-dimensional photos typically taken at an accident scene.
