iconometry|aɪkəˈnɒmɪtrɪ|
[ad. F. iconométrie (A. Laussedat 1892, in Ann. du Conservatoire d. Arts et Métiers IV. 374), f. Gr. εἰκονο- icono-: see -metry.]
The process of taking measurements from photographs of an area and using them to make a map or survey of it.
1898Ann. Rep. U.S. Coast & Geodetic Survey 1897 II. 628 Iconometry means the measuring of dimensions of objects from their perspectives (‘Bildmesskunst’), and this term could well be applied to those graphic constructions which serve to convert perspectives into horizontal projections; iconometry is the reverse of perspective drawing. 1923D. Clark Plane & Geodetic Surveying II. vi. 244 In plotting the map, the distances and elevations required must be obtained from the perspective dimensions on the photographs. The process—termed iconometry—is therefore the reverse of perspective drawing. 1934R. E. Davis et al. Surveying (ed. 2) xxvii. 787 The iconometry of aerial photographic surveying is much less accurate than that of terrestrial work.
Hence iconoˈmetric, -ˈmetrical adjs., employing or forming part of this process; iconoˈmetrically adv., in or by means of iconometry.
1898Ann. Rep. U.S. Coast & Geodetic Surv. 1897 II. 631 The correct orientation of the picture traces forms the most important part of iconometric plotting. Ibid. 630 If..two different perspectives..of the same object..are given, the dimensions and the position of the object with reference to the two stations may be determined iconometrically. 1906J. A. Flemer Elem. Treat. Phototopogr. Methods i. 6 It is not easy to make free-hand sketches of landscapes geometrically accurate enough to be used iconometrically in place of the landscapes. Ibid. vi. 121 (heading) Graphical iconometrical plotting methods. 1934R. E. Davis et al. Surveying (ed. 2) xxvii. 775 (heading) Iconometric interpretation of the stereoscopic view. 1944A. L. Higgins Higher Surveying iii. 219 [Photogrammetry.] Office Work. Apart from the preparation of negatives and prints, this consists of (1) plotting the triangulation, (2) iconometrical plotting, and (3) topographical mapping. |
