To clarify the extent of the importance of generalization and the extent of its impact on the topographic map, its importance, accuracy and function, the linear data was used on the topographic maps that represent the study area at a scale of 1: 25000, and circulated for transfer to the scale of 1: 50000 to bring it to a topographic map at a scale of 1: 100, 000, and accordingly the most important elements were presented Generalization, such as simplification, grouping, shrinking, exaggeration, displacement, smoothing, classification and coding, and clarifying the role of each of them in generalizing geographical features, and which of them is more influential in generalizing the different types of features.

The generalization of linear data has been divided into three types, which are the generalization of local symbols, the generalization of linear symbols, and the generalization of spatial symbols.

Through the generalization process on the three types, it was found that there is a clear difference in the characteristics of the symbols in the larger maps in the scale from the smaller maps in the scale despite the stability of the symbol shape.

The significance and accuracy of the symbol changed with the difference in the scale of the drawing, so the larger the map, the more detailed it was, i.

e.

more representative of reality.

Therefore, the generalization method that fits the scale was chosen in order to reach a topographic map representing the study area, while preserving the visual and spatial perception of the map so that it does not lose its value with the smallness of the scale and reach it to the best form in which it can appear.
