photogrammetry : The science of deducing the physical dimension of objects from measurements on photographs.
planimetric : The horizontal (x,y) locations of non-topographic features, such as rivers, lakes, buildings, roads, etc.
Photogrammetry - The art and science of accurately measuring objects on the earth's surface from a series of overlapping photographs (taken from aircraft or satellite).
Photogrammetry - "The art and science of obtaining reliable measurements through use of photographs" (Bonham-Carter, 1994, p. 371).
Photogrammetry uses aerial photographs to produce planimetric and topographic maps of the earth's surface and of features of the built environment.
Photogrammetry - The system of gathering information about physical objects through aerial photography and satellite imagery.
Photogrammetry
Deffinition and Basic Concepts
Photogrammetry is the technique of measuring objects (2D or 3D) from photo-grammes (= photographs).
Photogrammetry can be defined as the science of obtaining reliable measurements and producing maps by means of photography.

Photogrammetry The science of using aerial photographs and other remote sensing imagery to obtain measurements of natural and human-made features on the Earth. Photoperiod The duration of the daylight period.
An Adobe file format readable with free software (Acrobat Reader) photogrammetry Use of aerial photographs to produce planimetric and topographic maps of the earth`s surface and of features of the built environment.
The term may be taken broadly as comprising all the steps needed to produce a map: planning, aerial photography, field surveys, photogrammetry, editing, color separation, and multicolor printing.
For example an aerial photograph may need to be stretched (orthorectified) using photogrammetry so that its pixels align with longitude and latitude gradations (or whatever grid is needed).
Logan called attention to three developments that converged to create the vast changes that have taken place in photogrammetry and aerial sensing. First, the sensors themselves.
GPSs are also used in remote-sensing methods such as photogrammetry, aerial scanning, and video technology. GPS are becoming very effective tools for GIS data capture.
Detailed field surveys are conducted along the preferred route (collecting data using Global Positioning System, photogrammetry, light detection and ranging, and conventional surveying techniques) to map cultural, ecological, ...
Together with cartography, remote sensing, global positioning systems, photogrammetry, and geography, the GIS has evolved into a discipline with its own research base known as geographic information sciences.
Our team of civil, structural and geographical engineers and photogrammetry, remote sensing and CAD specialists provide remote services from Kochi, India to clients across four continents.
