Developing technology, like all other sciences, also influenced the science of historical geography. Thanks to developing information technologies, research questions in history and geography have become more quantitative and complete. The aim of the study is to find the land and residential usage patterns of the Üsküdar in the 1930s and to compare them with today's land and residential usage patterns. The study consists of two stages. Firstly, the 1/200 scale map prepared by J. Pervititch in 1930-1935 was geo-referenced with ArcGIS 10.1.1 program, and land use patterns were made. In the second phase, Üsküdar's land use patterns were digitized and compared with the insurance maps prepared by J. Pervititch. As a result of this, in the Uskudar in the 1930s, the total area of places such as garden, garden, house, place of worship, cemetery, the floor elevations of the houses and the physical conditions (old, new, demolished, wood, reinforced concrete), change in usage patterns were determined. In the 1930s, green areas, which accounted for 36%, decreased. The main reason for this decrease is the disappearance of some cemeteries. On the other hand, the area occupied by the streets and streets has increased. The main reason for this is the construction of new streets and streets in empty fields. There have also been some changes in the characteristics of the roads over time. In the years 1930-1936, there were 142 dead-end streets in the study area. Today, the number of dead streets is 83. The business and trade area of the city was also determined from the Pervitich maps. Between the years 1930-1936, the center of the city is the Üsküdar Pier. In the years 1930-1936, while the majority of the buildings were 1-2 storeys, it is now 5-6 storey. In the 1930s, an important part of the buildings was old and the number of buildings under construction is only one. The reason for this situation is the political and economic conditions of the period.
