Beschreibung:
Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The scale of a map in a given direction at any point is the ratio which a short distance measured on the map bears to the corresponding distance upon the surface Of the Earth. We must limit our definition to Mort distances because the scale of a map will generally vary from point to point; hence in defining scale we must confine ourselves to small elements of distance in the way which is familiar to every beginner in the differential calculus.
