The study focuses on using remote sensing to gather data about the Earth's surface, particularly in urban environments, using satellites and aircraft-mounted sensors. It aims to develop a classification framework for road targets using multi-spectral imagery. By integrating Convolutional Neural Networks (CNNs) with XGBoost, the study seeks to enhance the accuracy and efficiency of road target identification, aiding urban infrastructure management and transportation planning. A novel aspect of the research is the incorporation of quantum sensors, which improve the resolution and sensitivity of the data. The model achieved high predictive accuracy with an MSE of 0.025, R-squared of 0.85, RMSE of 0.158, and MAE of 0.12. The CNN model showed excellent performance in road detection with 92% accuracy, 88% precision, 90% recall, and an f1-score of 89%. These results demonstrate the model's robustness and applicability in real-world urban planning scenarios, further enhanced by data augmentation and early stopping techniques.

The primary purposes of this study are to identify the characteristics of land development in urban area through GIS and remote sensing techniques and to provide useful implications for urban spatial policy. To perform these tasks, Daegu metropolitan city and its vicinities were selected as a study area, and remote sensing data and attributed data were collected, organized and analyzed. This study focuses on the following three steps. First, it identifies the characteristics of land development in urban areas by utilizing multi-temporal satellite image data (Landsat TM, 1980, 1985, 1990, 1995, 2000 and 2005). Second, it tries to find an answer on a critical question concerning land use conversion, i.e., which land use leads expansion of urban area? Third, it derives implications for urban spatial policies based on these findings. The characteristics of the urban extents tell us that the main land use converted into urban use from non-urban uses is green areas. The public sector, central and local governments, leads the land use conversions of suburban lands as exclusive legal body to issue permission of land use change. Based on these findings, this study concludes that the more systematic and technically advanced management tools should be utilized for more effective spatial management for urban growth.

Through the fast economic growth since the 1960s, Korea has experienced various problems on land such as urban sprawl, the rapid increase in land prices, land speculation, privatization of the betterment, and so on. To prevent such problems and to enhance harmonious development and conservation, the National Land Planning and Use Act(NLPUA) was established in 2003. The NLPUA which was revised and combined two existing planning laws i.e. the National Land Use Management Act and Urban Planning Act, has an eye to preventing disorderly spatial development, to pursuing environmentally friendly spatial planning, and to following up planned development in non-urbanized area like rural area. This study aims to discuss what should be considered the pending issues after the application of the NLPUA in rural area. On the basis of reviewing the NLPUA in a viewpoint of the rural planning, this study suggests some improvement policy such as considering various rural conditions, securing excellent agricultural land, applying the District Plan II system effectively, reorganizing the planning administrative, and so on.

The world is currently undergoing an intense urbanization process. The percentage of urban dwellers has never been so high. In 2010, and for the first time, urban population surpassed the rural one, accounting for 51% of global population, and this trend will continue in the forthcoming years. This increment in concentration of population and supporting assets in cities, make their performance a critical issue for world population. Recent events such as Fukushima tsunami and the hurricane Katrina have shown how fragile built environments are and the unpredictability of occurrence and magnitude of the hazards. Such an expansion of the world's urban population, together with an increase in severity and number of hazards and catastrophes, has put under the spotlight the necessity to build cities not only sustainable, but resilient. Decision makers should acknowledge failure as an option, and the importance of developing city resilience. This paper will provide an initial review on urban resilience, definitions and assessment approaches as a first step for decision makers to account for resilience in their decision making process.
