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 ...
Today, aerial survey is often recognized as a synonym for aerophotogrammetry, a part of photogrammetry where the camera is airborne. Measurements on aerial images are provided by photogrammetric technologies and methods. [1] Aerial surveys can provide information on many things not visible from the ground.
On March 2, 2015 ASPRS released the new Positional Accuracy Standards for Digital Geospatial Data: [4] "The new ASPRS standards address recent innovations in digital imaging and non-imaging sensors, airborne GPS, inertial measurement units (IMU) and aerial triangulation (AT) technologies.
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 ...
The location is the primary factor used to integrate a very wide range of data for spatial analysis and visualization. Geomatics engineers design, develop, and operate systems for collecting and analyzing spatial information about the land, the oceans, natural resources, and manmade features.
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 ...
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.

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 ...
