Abstract
The definition of“contour line”is that all points on the surface of a matter, showing the intersection of the surface and a surface which is parallel to a given surface, either plane or curved, as a base. Such a line as this can be multiplied indefinitely at regular intervals.
The photogrammetry, by means of applying contour lines, enables to obtain a clear picture of the configuration of such objectives as the ground surface, a land material, a cultural heritage, a work of art, bacteria, a liquid, living creatures and vegetation, a significant structure and the surface of a heavenly body as the moon, the Mars and so forth.
My study on the possibility of reproducing a copy of the original through a contour map have revealed that it is largely dependent upon the stress put on the map at the time of preparation; realism, abstraction or the half-blood of these.
I have availed myself of a theory“the realism and the abstraction”to a key point of the reproduction as referred to the above.
