Close-range photogrammetry refers to the collection of photography from a lesser distance than traditional aerial (or orbital) photogrammetry. Photogrammetric analysis may be applied to one photograph, or may use high-speed photography and remote sensing to detect, measure and record complex 2D and 3D motion fields by feeding measurements and ...
Founded in 1934 as American Society of Photogrammetry and renamed in 1985, [1] the ASPRS is a scientific association serving over 7,000 professional members around the world. As a professional body with oversight of specialists in the arts of imagery exploitation and photographic cartography .
There are three forms of least squares adjustment: parametric, conditional, and combined: In parametric adjustment, one can find an observation equation h(X) = Y relating observations Y explicitly in terms of parameters X (leading to the A-model below).
Unlike an uncorrected aerial photograph, an orthophoto can be used to measure true distances, because it is an accurate representation of the Earth's surface, having been adjusted for topographic relief, [1] lens distortion, and camera tilt. Orthophotographs are commonly used in geographic information systems as a "map accurate" background ...
Photo interpretation at the U.S. National Photographic Interpretation Center during the Cuban Missile Crisis.. Aerial photographic and satellite image interpretation, or just image interpretation when in context, is the act of examining photographic images, particularly airborne and spaceborne, to identify objects and judging their significance.

Aerial imagery is a common asset in military matters, but 3D maps can be difficult to collect on short notice without specialized equipment. This new photogrammetry technique from the Army Corps ...
The use is accurate as only qualitative considerations are needed. It is fast enough to respond to the monument’s immediate management needs. [ 34 ] The first operational phase is an accurate preparation of the photogrammetric surveying where is established the relation between best distance from the object, focal length, the ground sampling ...
Associated with three-dimensional (,,) data and topography, TINs are useful for the description and analysis of general horizontal (,) distributions and relationships. Digital TIN data structures are used in a variety of applications, including geographic information systems (GIS), and computer aided design (CAD) for the visual ...
