Analysis of the Spatial Spread of Unplanned Slums Areas in Zagazig City, Egypt Using Geographic Information Systems.
The research dealt with the application of the analysis of the spatial spread of slums housing areas in the city of Zagazig using geographic information systems by knowing the location of the city of Zagazig, and the pattern of the spatial distribution of unplanned slums housing areas, and categorizing them in terms of the area into (large areas, medium areas, and small areas), then it was Determining the spatial spread of these areas within three areas: the central area of the city with a radius of 1.5 km, the area located on the boundaries of the urban boundary at a distance of about 1.5: 3 km, and the area outside the urban boundary, including Shaybah and Al-Nakariah, about 3: 4.5 km, and through that analysis, the priorities Dealing with these areas according to the proximity to the central region. The priority is for the closest and largest area, and the results were, in order, the following unplanned slum areas: 16, 36, 21, 27, 31, 32, 33, 15, 35, 37, 34. 17, 24, 28, 20, 22, 19, 39, 38, 30, 25, 8, 4, 26, 23, 5, 7, 29, 12, 18, 2, 13, 14, 6, 3, 11, 9, 10, 1.
Steps to reproduce
First: The patterns of slums in Zagazig city were classified according to the area factor into three main types (small slums, medium slums, and large slums)(Walid bin Saad Al-Zamil, 2019) in addition to their classification approved by the Slums Development Fund, which is unsafe areas, unplanned areas, and random markets...Nand that through the study we found that there are no unsafe slum areas in Zagazig city and that we will focus on unplanned slum areas only because the markets are far from the issue of random housing. Second: The spatial spread of these areas was determined within three areas: the area of the central area of the city with a radius of 1.5 km, the area located on the boundaries of the urban boundary at a distance of approximately 1.5: 3 km, and the area outside the urban boundary including Shaybah and Al-Nakari area at a distance of approximately From 3: 4.5 km. Third: The study used spatial analysis to describe the characteristics of the distribution of slum areas and their concentration in the city of Zagazig, and to extract a comprehensive map of slums through the geographic information system. Fourth: The methodology dealt with the analysis of the study variables using the SPSS statistical analysis software, Microsoft Excel 2010, to determine the percentages of the distribution of random scattering and its characteristics within the spatial space, and then elicit the relationship between spatial and areal characteristics to reach research results that can be generalized
