Coding of the Qualitative Maps in Geographic Information Systems GIS and Evaluated Cartographically

Abstract

This article focuses on explaining the Geocoding in general and the cartographic symbolization in particular, which is a crucial factor in map representation, particularly qualitative map symbolization. This type of symbolization emphasizes the location and distribution of the phenomenon under study without considering quantitative differences. The article categorizes this symbolization into point, line, and area symbols, and discusses the appropriate contexts for each type. There are various symbols available within Geographic Information System (GIS) programs; however, the choice of symbol type, style, and size is not determined by the software itself but is governed by the principles and standards of cartographic design. It is imperative for the cartographer to be thoroughly knowledgeable about these principles and standards, both in general and in detail, given the critical importance of symbols in map interpretation by the reader.
