공간통계자료를 활용한 도시재생사업 대상지 변화의 시각화 분석 - 대구광역시 2018년 도시재생뉴딜사업지를 대상으로 -

초록

Purpose: Urban regeneration projects are important as they involve a large amount of public funds and manpower. However, due to discrepancies between site boundaries and statistical data, the evaluating its effects by ‘Dong’ ministrative units in Korea is limited. Method: This study established criteria to evaluate the effectiveness of the target site and visualized spatial the data using Geographic Information System (GIS). The evaluation indicators were set as the number of productive population in the population and social sector, the number of businesses in the industrial and economic sector, and the number of new buildings in the physical environment sector. The measurement was collected in a square shape of 100×100m as grid boundary data (SHP format) and grid statistics (txt format) between the increase and decrease values between 2017, before the project implementation, and 2021, when the project was being implemented. We compared it with the statistical values of the administrative district units in terms of project type, adjacent area, and special pattern, by evaluation indicator and target area. Result: The results of this study suggest that it is valuable to use GIS to visualize grid-shaped spatial statistical data, to improve the ease and accuracy of measuring evaluation indicators in the project boundary area, and to intuitively grasp the change pattern of diagnostic indicators through exploratory visualization, for monitoring the measurement of project effect evaluation and for setting up hypotheses for follow-up studies.
