Industry:Earth science
The magnitude of an object, determined by measuring the photographic densities on a photograph taken using emulsions filters with combined sensitivities equivalent to the sensitivity of the human eye. Hence, photovisual magnitudes are practically equivalent to visual magnitudes.

(1) A map projection based on some common, known map projection which has been changed by relocating the point or line or zero distortion and by specifying the scale along different lines. (2) A map projection differing slightly from the named map projection on which it is based. (3) A graticule having the oblique aspect of the named map projection and obtained by calculation.

Industry:Earth science
The creation, on a map, of the impression that the scene is obliquely illuminated, by plotting the intersections of a series of parallel, equally-spaced, inclined planes with conventional contour lines. Through these intersections, isograms are drawn representing the perpendicular distances above or below a hypothetical plane which intersects the plane of mean sea level at a constant and predetermined angle. These isograms are sometimes described as inclined contours. The method was first proposed by Kitiro in 1932.
Industry:Earth science
An urban or suburban residential or commercial locality having considerable homogeneity as to housing, tenancy, income and characteristics of the people in it. Neighborhoods are often outlined by physical barriers such as railroad tracks, streams, commercial or industrial buildings, type or age of buildings, hills or ravines, or by lines created by the construction of subdivisions, differences in zoning ordinances, or restrictions in deeds.
