  • This study aims to analyze the effectiveness and differences of the weighted concepts of the weighted ERAM models within urban spatial analysis. This study confirmed that the existing weighted ERAM models differed in analytical power depending on the analysis target. This study also applied the weighted concepts in various ways to urban areas with different spatial structures. This study is significant in that it has a variety of approaches to the combination of weighted concepts applied to the ERAM model. The organically-occurring urban spatial structure was the most effective with the building population-weighted ERAM model. The planned urban spatial structure containing organic structures was most effective with the building population-distance multi-weighted ERAM model. Finally, the orthogonally planned urban spatial structure was the most effective with the building population-angle multi-weighted ERAM model. Each weighted concept showed a relatively higher correlation according to the different urban spatial structures than other weighted concepts in the analysis between ERAM results and floating population.

  • Modern railway construction by Japanese had a great influence on the urbanization, transformation of urban structure and landscape during the Japanese imperialism and compressive increasing period in Iri(Iksan). This paper aims to find out the effect of railway on the modern urban structure and urban landscape in Iri(Iksan). Railways in Iri, Honam railway, Kunsan railway, Jeonla railway have been constructed progressively during 1911 and 1915 with Iri and old Iri(east-Iri) station. From the analysis of land registration maps and street plans, old photographies and historical records, some significant features underling railway construction can be followed in view of modern urbanization process in Iri. Firstly railways cut off the possibility of developing urban structure based on traditional spatial structure of Iksan. Secondly railways made dual spatial structure in Iri. Japanese and Korean life zone were divided into separate district around urbanization area and market place. Thirdly traditional space cognition system based on four cardinal directions were changed to front and rear space of railway station. Fourthly railways and stations caused neo-baroque spatial order and imperialistic urban landscape of Iri with axis, vista and gridiron plan. Fifthly break points and fringe belts garbling modern urbanization process are created. Sixthly modern cultural and consumptive urban spaces were taken their seats in relation with daily urban life.

  • The purpose of this research is to clarify the relationship between the location of markets and the spatial structure of historic center in Beijing of 18th century by network analysis method onto the historic map of Beijing 'Qianlong-Jincheng-Quantu(乾隆京城全圖)' produced in 1750. By categorizing the grade of each market, it is revealed that the location of markets in Beijing under Qing Dynasty was not only decided by the various factors as policy of the regime and traditional social usages but also by the spatial structure of urban space in historic part of the city. At the same time, the sociopolitical factors and the spatial structure of urban space might influence reciprocally in defining the physical state of urban space.

  • In this study, the change characteristics of urban spatial structure in Daegu were analyzed connecting with urban planning for efficient urban management. Urban development process from 1970 to 2010 in Daegu was analyzed utilizing Getis-Ord $G_i^*$ methodology, a spatial statistical method, and it was identified that Daegu was in the stage of disurbanization. However, as Daegu orients multi-nuclei city, it was difficult to explain the stage of urban development after disurbanization in 2000. Accordingly, to analyze detailed changes in spatial structure in multi-centric areas after 2000, population, land price and employment factor changes were analyzed using Bachi Measurement. According to analytical results, multi-centralization process has been continued in Daegu. Urban core area and Chilgok area showed spatial structure change into distribution process, Ansim area into concentration process, and Seongseo and Talseo area into concentration and distribution process. Therefore, urban planning considering the regional characteristics are needed for efficient urban management.

  • Land price is a kind of text to read urban spatial structure. The purpose of this paper is to inquire into the characteristics of Daegu's urban structure and its change in time through exploring spatio-temporal variations of land price with a detailed spatial and temporal resolution. To achieve this, land value surfaces were represented using the officially assessed land price every other year from 1995 to 2011. Through mapping and exploring spatio-temporal patterns and fluctuation rates of land price for this period, changes in urban structure, the effects of local decision makings such as Greenbelt adjustment, housing site development, and gentrification, and the effects of business fluctuations or policies at global or national scales could be caught. In addition, the trends for suburbanization and multi-centric urban form could be examined from the results of a negative exponential model explaining the effect of distance from an urban center on spatial variation of land price. These results demonstrate that urban analysis using land price mirroring spatial decision making at various scales could deepen understanding for internal structure and change of a city and provide useful information for establishing regional and urban development policies and evaluating their effects.

  • In this paper, we propose a system to detect spatial structures in land cover maps and to detect time-series spatial structure changes. At first, the proposed system detects patches in a certain area at different times and calculates their measures to analyse spatial structure patterns of the area. Then the system conducts patch mapping among the detected time-series patches and decides 6 types of patch changes such as keeping, creating, disappearing, splitting, merging, and changing in a mixed way. Also, the system stores the patch-based spatial structure patterns of time-series land cover maps in binary form to extract changes. This demonstrated that the proposed change detection system can be used as a basis for planning the reconstruction of the urban spatial structure by measuring the degree of urban sprawl.

  • Transformations of the urban spatial structure, from sub-area redevelopment to newtown development, results great influences upon existing urban condition and spatial configuration. The purpose of the study is to analyse the effect of the urban spatial configuration of Uijongbu city where experienced changes after newly development of city center and new residential area. The west part of the city where is limited in growth by military bases, ego U.S Army basecamp, were planned and established as the other axis of the city center since mid 1980's. After that new residential area which is located in far east of the city were also developed. Space syntax as a methodology has been adopted to conduct quantitative analysis which is able to interpret differences between sub-areas ; old city center, new city center, new residential area. The results of the analysis are follows ; 1) existing structure of the urban fabric, especially old city center, is sustained and intensified, 2) new city center which is west part of the city has failed to achieve organic spatial connection adjacent to old city center, 3) there is less spatial depecdency relationship between city center and new residential area where is identified as another small self-support city within the city.

  • In recent times, multi-centralization and decentralization as well as large Capital area and suburbanization in the spatial structure of capital area. With rapid growth, urbanization and industrialization are unsystematic, and growth inequality between regions caused negative effects such as discordant centralization and decentralization, fluctuating land value, and gap between living conditions. Accordingly, this study analyzed urban spatial indexes by the self-governed body in the capital area such as Seoul, Incheon, and Gyeonggi province for the analysis of the regional inequality phenomenon. We examined the characteristics of temporal and spatial changes in urban spatial structure in the capital area by utilizing the distribution pattern and density of city indexes such as population, employment, etc, and then drew the commonality of those factors through factor analysis. We evaluated the drawn results through the city standard index by each city, conducted factor score analysis, and identified the interaction between each factor and Housing Purchase Price Composite Indices index, housing rent price index(Housing Jeonse Price Composite Indices), land price fluctuation rate, diffusion ratio of house, and financial independence.

  • The main purpose of this study is to identify urban spatial structure by applying geographic information system and remote sensing data. This study identifies the urban spatial structure of non-megalopolis by analyzing the spatial distribution of population and employment in the case of Daegu metropolitan area. For this purpose, multi-temporal satellite image data (Landsat TM; 1995, 2000 and 2005) were utilized through the geographic information system. The distance-decay estimations in terms of population and employment density show that Daegu region as a whole shows monocentric urban characteristics. However, some evidences of polycentricism such as low explanation power of monocentric urban model, rises in multiple employment centers, decentralization of employment are emerging.
