Abstract EN

This paper aims to study the visual variations that play an important role in the creation of point symbols and to identify their potential, sphere of utility in representing milestones on maps, the specification of the role of visual perception and variations in spotting map content as well as the recognition of the ideal manner for an active and influential use of visual variations in map design.

The visual analysis method and the cartographic methods have been adopted to reach the paper target.

It has been done in three phases whereas the role and importance of the visual perception were clarified in the first phase.

In the second one a detailed study on most of the visual variations of point symbols has been done, whilst in the third phase a general analysis for visual variations was fulfilled.

The study reached various conclusions such as: 1) The visual variations vary in pointing the geographical features properties.

2) The necessity of studying the visual variations of point symbol.

3) Each visual variation can fit only one or two element of coding, for example size variable is for quantitive coding and shape variable is for qualitive coding.

Thus the study showed that the abstract and visual symbols are preferable in point coding.
