Panchromatic, natural color or color infrared aerial photographs can be acquired from metric film cameras, or multispectral digital imagery can be acquired from digital metric cameras. The term altitude is often used interchangeably with 'height. Aerial imagery allows users to realistically see the landscape from above and used to resolve disputes that might occur from other technologies. Altitude In geometry, the altitude of a geometric figure generally refers to a perpendicular distance measured from the base of the figure to its opposite side.The precise focal length, principal point coordinates, and various forms of lens distortion are carefully calibrated so that systematic distortions can be accounted for and corrected. Extremely high spatial accuracy achieved using calibrated metric cameras.The hyperbola is the set of all points in a plane, the difference of whose distance from two fixed points in the plane is a positive constant.
Hyperbola : A type of conic section or symmetrical open curve. Histogram : A graph that uses bars that equal ranges of values.
Photogrammetry is typically used to create topographic maps which depict the three-dimensional shape and features of the ground onto a two-dimensional surface, and can also be used to produce contour line maps or Digital Terrain Models (DTMs), map corrected aerial imagery, and planimetric feature maps.Īdvantages offered by aerial photogrammetry include: Hexagon : A six-sided and six-angled polygon. Aerial photogrammetry enables the accurate mapping of 3D coordinates on the ground, using 2D coordinates measured on stereo aerial photographs that see the same points on the ground from two or more different perspectives. Photogrammetry is the science of making measurements and mapping from digital or hardcopy photographs. The definition of an Altitude of a triangle is a line segment from one vertes perpendicular to the line containing the opposite.
