  • In this paper, we propose the methodology and system to show weather information to spatial system. When using the spatial information system, it is easy and convenient to show information such as target location, mission contents, enemy threats and so on. However, drawing 1-dimensional weather information on 3-dimensional space in spatial information system is hard task. To fuse data, we need to add a spatial layer including weather information to spatial layers and perform space modeling for showing weather information as spatial data in a virtual space. The virtual space is shown by receiving meteorological data and then changing in real time through weather database linkage.

  • 세계 여러나라들은 자국의 업체와 소비자 보호를 목적으로 다양한 인증제도를 운영하고 있으며, 이는 상대국으로 하여금 무역장벽으로 작용하고 있다. 또한, 기존에 시행되고 있는 KS, KCC등 품질인증 관련 제도가 공간정보 분야의 특성을 충분히 반영하지 못하고 있다. 따라서 본 연구는 기존의 품질 인증제도와 사례분석을 통하여 공간정보 기기 품질인증(안)을 마련하고자 하였다. 본 연구에서는 첫째, 공간정보 기기 품질인증에 필요한 기본개념을 정립하였고 둘째, 공간정보 기기의 품질인증 범위와 내용 및 절차를 세부항목으로 분류하여 설정하였으며, 마지막으로 국내외 유사인증제도의 특성과 비교하여 실증적인 품질인증제도 도입을 위한 기본방향을 제시하였다.

  • Recently, there has been rising concerns to integrate and connect a developed spatial information services without consideration of location in the heterogeneous distributed environment. The Open GIS Consortium provides system architecture model related to open web service for spatial information. This paper discusses the issues related to the web service framework for spatial information services using standards of Open GIS Consortium. In particular, we concentrate upon the WRS that support the runtime discovery and evaluation of resources. The technology for integration of spatial information services is expected to get synergy effect and overcomes limit of individual development of each spatial information technology. Also this system provides the interoperability and the reusability and prevents the duplication development of system.

  • The environment of Ubiquitous in terms of improvement is being expanded to various fields and time enabled system. Thus, a real-time spatial information management system has been developed by integrating a human movement detection system into a SICS(Spatial Information Control System) engine that can integrally manage inside spatial information extracted from 3D CAD and outside spatial information of GIS. The add-on program was developed to extract spatial information necessary for the SICS engine from 3D CAD information, and a human movement detection system was developed. Test bed was operated for 2weeks and indoor human flow information was found out by zone. Also, the direction of future research was decided through a test bed.

  • Land Surface Temperature (LST) is the radiological surface temperature which observed by satellite. It is very important factor to estimate condition of the Earth such as Global warming and Heat island. For these reasons, many countries operate their own satellite to observe the Earth condition. South Korea has many landcovers such as forest, crop land, urban. Therefore, if we want to retrieve accurate LST, we would use high-resolution satellite data. In this study, we made LSTs with 4 LST retrieval algorithms which are used widely with Landsat-8 data which has 30 m spatial resolution. We retrieved LST using equations of Price, Becker et al. Prata, Coll et al. and they showed very similar spatial distribution. We validated 4 LSTs with Moderate resolution Imaging Spectroradiometer (MODIS) LST data to find the most suitable algorithm. As a result, every LST shows 2.160 ~ 3.387 K of RMSE. And LST by Prata algorithm show the lowest RMSE than others. With this validation result, we choose LST by Prata algorithm as the most suitable LST to South Korea.

  • The real-time traffic data is generated continuous and unbounded stream data type while intelligent transport system (ITS) needs to provide various and high quality services by combining with spatial information. Traditional database techniques in ITS has shortage for processing dynamic real-time stream data and static spatial data simultaneously. In this paper, we design and implement an advanced traffic monitoring system (ATMS) with the integration of existed data stream management system (DSMS) and spatial DBMS using IntraMap. Besides, the developed ATMS can deal with the stream data of DSMS, the trajectory data of relational DBMS, and the spatial data of SDBMS concurrently. The implemented ATMS supports historical and one time query, continuous query and combined query. Application programmer can develop various intelligent services such as moving trajectory tracking, k-nearest neighbor (KNN) query and dynamic intelligent navigation by using components of the ATMS.

  • 최근 공간 정보들을 효과적으로 이용할 수 있는 기술에 대한 연구가 활발하게 이루어지고 있다. 효율적인 지식 탐사를 위해 다양한 기존의 데이터 마이닝 방법들이 확장되어 공간 데이터 마이닝에 사용되고 있다. 그러나 기존의 공간 연관 규칙 탐사 시스템들은 프레디킷 간의 연산을 통해 규칙을 발견함에 따라 질의 결과에 다양한 비공간 속성들을 반영하지 못하는 문제점을 가지고 있다. 본 논문에서는 이러한 문제점을 해결하기 위해 공간 데이터베이스에서 사용되는 질의를 확장하고, 위상정보에 따른 데이터를 구성한 후 비공간 객체 속성간의 연관 규칙을 발견하는 시스템을 제안한다. 특히 지리 정보 시스템에 적용 가능한 모델을 구현하였다. 이렇게 구현된 시스템은 사용 중인 공간 데이터베이스를 확장하므로 이식성이 뛰어나고, 공간 속성뿐만 아니라 다양한 비공간 속성을 고려함으로써 좀 더 실생활에 유용한 공간 연관 규칙을 발견할 수 있다.
