최근 국가적으로 환경정보들을 DB화하고, 체계화하며 통합하고자 하는 움직임이 활발히 전개되고 있는 있다. 이러한 노력은 특히 도시 및 지역차원에서 수립하는 법정계획인 환경보전계획의 공간계획화를 더욱 용이하게 하며, 이는 공간의 관리방향을 보다 명확하게 함으로써 토지의 보전은 물론 이용과 관련된 각종 계획들 간의 상충을 합리적으로 조정하도록 합의하는데 용이한 수단이 될 것으로 보인다. 이에 본 연구는 환경보전계획의 공간계획화를 위한 방안을 모색하였으며, 특히 환경요소 중 가장 민감한 자원으로 인식되는 생태환경을 중심으로 한 공간환경계획 수립방안을 제시하였다. 공간환경 계획 수립방안은 계획과정을 고려해 크게 1)기본방향, 2)공간정보의 수집, 3)공간환경현황 작성, 4)공간환경 관리계획 수립으로 구분하였으며, 특히 현황파악 및 계획수립 시 필요한 공간정보는 기존에 구축된 공간정보들을 최대한 활용할 수 있도록 국가나 지자체 차원에서 구축된 공간정보들을 목록화 하였다. 계획수립 시 고려되는 현황도는 토지이용(토지피복)과 자연생태 우수자원/지역 현황 작성방안을 제시하였으며, 이를 기반으로 광역생태축 계획과 보전, 복원지역 계획을 수립함으로써 생태환경을 고려한 환경보전계획의 공간화를 모색하였다. 기존연구 및 사례들을 통해 마련한 현황 및 계획방안은 경기도 지역에 적용해 봄으로써 그 활용가능성을 살펴볼 수 있었다. 이러한 계획은 관련 공간개발계획 수립 시 생태적 가치와 중요도를 고려한 계획안 마련에 기여함은 물론, 지역 내 개발사업 추진 시 계획의 적정성과 입지의 타당성을 검토하는 기초자료와 근거자료로 활용될 수 있을 것으로 보인다.

Public outdoor spatial environment and its convenient facilities are playing an important role in providing space for various student activities in university campus. Previous studies have shown that many socio-demographic-economic students' background and motivation have impacted the level of academic achievement. Moreover, research also contended that school facilities at some points also influenced students' academic performance. Thus, the aim of this research was to investigate the relationship between the level of academic achievement and satisfaction of various spatial environment through survey. For that purpose, one university campus was selected and evaluation indexes were categorized into five major components of physical and experimental environment, later supported by factor analysis. Correlation analysis found that extracted factors were significantly interrelated to academic achievement. Further, regression analysis also explored sense of belonging as major predictor of academic achievement. Finally the study suggested that campus plan be approached carefully, because such experimental environment as diverse club activities at outdoor environment is a key element to academic achievement even though rated low scores in satisfaction.

The purpose of this study is to build a database of Spatial information Bigdata of cities using satellite images and spatial information, and to examine the correlations with the surface temperature. Using architectural structure and usage in building information, DEM and Slope topographical information for constructed with 300 × 300 mesh grids for Busan. The satellite image is used to prepare the Normalized Difference Built-up Index (NDBI), Normalized Difference Vegetation Index (NDVI), Bare Soil Index (BI), and Land Surface Temperature (LST). In addition, the building area in the grid was calculated and the building ratio was constructed to build the urban environment DB. In architectural structure, positive correlation was found in masonry and concrete structures. On the terrain, negative correlations were observed between DEM and slope. NDBI and BI were positively correlated, and NDVI was negatively correlated. The higher the Building ratio, the higher the surface temperature. It was found that the urban environment DB could be used as a basic data for urban environment analysis, and it was possible to quantitatively grasp the impact on the architecture and urban environment by adding local meteorological factors. This result is expected to be used as basic data for future urban environment planning and disaster prevention data construction.

Radon is an invisible, odorless, and radioactive gas. It is formed by the disintegration of radium, which is a decay product of uranium. Some amounts of radon gas and its products are present ubiquitously in the soil, water, and air. Particularly high radon levels occur in regions of high uranium content. Although radon is permeable into indoor environment not only through geological features (bed rock and permeability) but also through the construction materials and underground water, the radiation from the geological features is generally main exposure factor. So there can be a problem in a certain space such as the underground and/or relatively poor ventilation condition. In this study, a GIS technique was used in order to investigate spatial distribution of radon measured from sub- way stations of 1 thru 8 in Seoul, Korea in 1991, 1998, 2001, and 2006. Spatial analysis was applied to reproduce the radon distribution. We utilized spatial analysis techniques such as inverse distance weighted averaging (IDW) and kriging techniques which are widely used to relate between different spatial points. To validate the results from the analyses, the jackknife technique for an uncertainty test was performed. When the number of measuring sites was less than 100 and also when the number of omitted sites increased, the kriging technique was better than IDW. On the other hand, when the number of sites was over 100, IDW technique was better than kriging technique. Thus the selection of analytical tool was affected sensitives by the analysis based on the number of measuring sites.

Diverse geostatistical tools such as kriging have been used to estimate the volume and spatial coverage of contaminated soil needed for remediation. However, many approaches frequently yield estimation errors, due to inherent geostatistical uncertainties. Such errors may yield over- or under-estimation of the amounts of polluted soils, which cause an over-estimation of remediation cost as well as an incomplete clean-up of a contaminated land. Therefore, it is very important to use a better estimation tool considering uncertainties arising from incomplete field investigation (i.e., contamination survey) and mathematical spatial estimation. In the current work, as better estimation tools we propose stochastic simulation approaches which allow the remediation volume to be assessed more accurately along with uncertainty estimation. To test the efficiency of proposed methods, heavy metals (esp., Pb) contaminated soil of a shooting range area was selected. In addition, we suggest a quantitative method to delineate the confident interval of estimated volume (and spatial extent) of polluted soil based on the spatial aspect of uncertainty. The methods proposed in this work can improve a better decision making on soil remediation.

In this paper, we present multi-sensor data fusion for telematics application. Successful telematics can be realized through the integration of navigation and spatial information. The well-determined acquisition of vehicle's position plays a vital role in application service. The development of GPS is used to provide the navigation data, but the performance is limited in areas where poor satellite visibility environment exists. Hence, multi-sensor fusion including IMU (Inertial Measurement Unit), GPS(Global Positioning System), and DMI (Distance Measurement Indicator) is required to provide the vehicle's position to service provider and driver behind the wheel. The multi-sensor fusion is implemented via algorithm based on Kalman filtering technique. Navigation accuracy can be enhanced using this filtering approach. For the verification of fusion approach, land vehicle test was performed and the results were discussed. Results showed that the horizontal position errors were suppressed around 1 meter level accuracy under simulated non-GPS availability environment. Under normal GPS environment, the horizontal position errors were under 40㎝ in curve trajectory and 27㎝ in linear trajectory, which are definitely depending on vehicular dynamics.

The Location Based Services (LBS) comprise spatial information and mobile technology allow users to receive various services based on Global Positioning Systems (GPS). Although, spatial information based services are very useful, it has lots of possibility to damage privacy protection. But the contents of the legislation by government have problems conflicted between protection of a person's location information and invigoration LBS. Therefore, in this study suggest a causal model to deal with user satisfaction and factors affecting spatial information based services to customer perspective. The proposed research model is tested empirically with one hundred and forty one usable questionnaires and partial least square (PLS) method. Experimental results showed that the usefulness, playfulness, and service quality play a prominent role in influencing the spatial information services satisfaction compared to other factors. But, easy of use and perceived risk are not significant.
