Specific maps and the basics of representation in urban land uses

Abstract

The cyclone coding of geographical phenomena is one of the topics that has been interested in many researchers in the design of maps and its drawing because it has a great role in reducing information, elaborating it and representing it with new ideas. Given the absence of a map study on digital coding of urban lands in the municipality of Kadhimiya, it is one of the necessary requirements numbers and drawing a group of objective maps that deal with the distribution of a number of urban land uses according to the foundations and rules of appropriate Khargi representation. The study area in Al -Kadhimiya municipality is chosen due to the lack of a detailed study on the maps of this region. To clarify the information and its numbers and deliver it accurately to the map reader.

The primary goal of research is to show the number of specific digital maps symbols using the geographic information systems program by choosing the qualitative symbols for each phenomenon or using and representing it on the map after it is chosen in a deliberate way in line with the type, nature and specifications of the phenomenon that can be represented and on this basis adopt a process reading and analyzing the map. The researcher touches on the concept of coding and its types (symbols, linear symbols and surveying symbols) and the most important problems that the cartovia suffers when they are represented in the maps of urban land uses as well as mentioning the most important basic rules to be followed when represented by each type of symbols and choosing the most appropriate ones in acting to be more aware of the map reade .
