The types of service using location information are being various and extending its domain as wireless internet technology is developing and its application part is widespread, so it is prospected that LBS (Location-Based Services) will be killer application in wireless internet services. The MODB (Moving Object Database) stores and manages very large current/ past moving object data, so it is very important part in LBS platform. The performance of LBS platform is tightly depending on the performance of this MODB. The other important part is alerting engine in LBS platform, which is system to transmit various value-added information or notify emergency information to mobile phone after triggering specified events. This alert engine is supported as extended function of MODB, that is to say, the alerting function is closely related with MODB. So alert cartridge on MODB must provide not only moving point triggering about going into, going out specified geographical area but also batch alerting about nearest neighbor from specified geographical area. In this paper, we study of extended part on MODB to support the alert engine. And we design alert engine cartridge on MODB before implementing the system.

최근, BIM(Building Information Modeling)은 계획부터 유지관리까지 SOC 시설물의 전 생애주기 단계에 걸쳐 적용되고 있다. BIM이 시설물의 내부 공간 분석에 초점을 맞춘 도구인 반면, GIS(Geographic Information System)는 시설물 간의 관계 분석에 주로 이용된다. 따라서 BIM 과 GIS를 통합한다면, SOC 시설물의 효과적인 정보관리와 다양한 해석이란 측면에서 상당한 시너지 효과를 발휘할 것으로 기대된다. 본 논문은 지방자치단체에 BIM/GIS 통합플랫폼을 적용하기에 적합한 SOC 시설물의 우선순위를 선정하는 방안을 다루고 있다. 첫째, 법에서 규정하는 시설물을 분석하고, 이 중 SOC 성격에 맞는 시설물을 설정한다. 둘째, 각 SOC 시설물에 대한 BIM/GIS 통합 플랫폼의 적용성 및 효용성을 분석한다. 적용성 및 효용성을 정량화하기 위하여 UIS 관리대상 측면과 GIS 분석기능 측면의 분석을 수행하였다. 마지막으로, BIM/GIS 통합 플랫폼 적용을 위한 SOC 시설물의 우선순위를 선정한다.

The purpose of this research is creating the visualization platform of the user interface to make able to be provide the demanded service while users communication with surrounding space in a smart city environment. This comes from the latest enhanced interface technology and social media, and it uses the shares information to support the proper interface environment according to a life style and spatial properties. "EzCity" which is the user interface platform suggested in this research, can control the enormous amount of public data for the smart city. The core module of user platform is made up with Public data module, Interface module, Visualization module and Service module. The role of this platform is to be provide "Geo-Intelligent Interface Service" for space users to access the data in easier and more practical interface environment. This reinforces the visualization process for data collecting, systematization, visualization and providing service. Also this will be expected to be the base to solve the problem which complexity and rapidly increasing amount of data.

Large-scale natural disasters such as typhoon and localized torrential downpour cause widespread human and property damages. Recently, management systems using GIS are being developed to manage such disasters from various angles. Integrated disaster management encompasses diverse areas such as prediction through the computation of disaster information and field support for response. The development of disaster information systems must also consider the installation of various computation modules. Furthermore, GIS is generally included for realistic description of the field situation and for spatial operations. This study aims to develop the core module of a visualization platform for the 3D GIS services of integrated disaster information using Unity engine This system will enable integrated disaster management from various angles, encompassing disaster prevention experts, field support personnel, and citizens.

In this paper, I examines the spatial representation of the change in the environment of the digital platform, and play the game with a focus on the spatial characteristics of a digital game. First, what is the Spatial characteristic of digital games? This section applies to a digital game "theory of Lefebvre", and the spatial representation of the practice space, divided into representational space were explored. Second, how to express dealing Is there space in the genre of adventure games? The spatial characteristics of the game medium through the Spatial characteristic of the adventure game genre that is most striking examples was analyzed whether the expression in any way. Consequently, the spatial characteristics of the digital game studies of the game as well as think a very large role in the development direction. In addition, this case analysis of the expression is the basis of this digital game that is utilized in many areas, and I am sure many possibilities to find a positive role in the game.

최근 해양레포츠 산업이 블루오션으로 떠오르고 있는데, 해양레포츠는 조류, 수온, 염도 등과 같은 다양한 환경조건에 영향을 받기 때문에 관측자료 뿐만 아니라 모델 예측자료도 매우 필요한 정보이다. 본 연구에서는 연안해양모델인 FVCOM(Finite Volume Coastal Ocean Model)에서 산출된 예측자료를 웹 및 스마트폰을 통해 제공하는 시각화시스템을 구현하였다. 이를 위하여 FVCOM 자료에 내삽과 샘플링 등의 전처리를 하여, 조위, 수온, 염도의 래스터 이미지와 조류(유속, 유향)의 벡터 데이터베이스를 구축하였고, 스프링 프레임워크(Spring Framework)를 활용하여 REST(Representational State Transfer) 기반의 API(Application Programming Interface)를 제공하는 웹서비스를 구축하였다. 또한 데이터베이스 자료를 데스크톱 및 이기종의 스마트폰에 탑재시킴으로써 크로스플랫폼(cross-platform) 시각화 환경을 실현하였다.

This paper proposes an algorithm for automatically converting and displaying rainfall radar data on a 3D GIS platform. The weather information displayed like rainfall radar data is updated frequently and large-scale. Thus, in order to efficiently display the data, an algorithm to convert and output the data automatically, rather than manually, is required. In addition, since rainfall data is extracted from the space, the use of the display image fused with the 3D GIS data representing the space enhances the visibility of the user. To meet these requirements, this study developed the Auto Data Converter application that analyzes the raw data of the rainfall radar and convert them into a universal format. In addition, Unity 3D, which has good development accessibility, was used for dynamic 3D implementation of the converted rainfall radar data. The software applications developed in this study could automatically convert a large volume of rainfall data into a universal format in a short time and perform 3D modeling effectively according to the data conversion on the 3D platform. Furthermore, the rainfall radar data could be merged with other GIS data for effective visualization.
