  • Car-mounted MMS (Mobile Mapping System) is the most effective tool for mapping of high definition road maps(HD Map). The MMS is composed of various sensor combinations, and the manufacturing methods and processing software are different for each manufacturer, performance cannot be predicted only by the specifications of the parts. Therefore, it is necessary to judge whether each equipment is suitable for mapping through performance evaluation, and facilities for periodic performance evaluation. In this paper, we explained the MMS performance evaluation facilities built at the SOC Evaluation Research Center of Korea Institute of Civil Engineering and Building Technology and analyzed the conditions that the evaluation facilities should have through a literature survey and field tests.

  • Nowadays, spatiotemporal data models deal with objects which can be potentially useful for wide range applications in order to describe complex objects with spatial and/or temporal facilities. However, the information needed by each application usually varies, specially in the geographic information which depends on the kind of time oriented views, as defined in the modeling phase of the spatiotemporal geographic data design. To be able to deal with such diverse needs, geographic information systems must offer features that manipulate geometric, space-dependent(i.e, thematic), and spatial relationship positions with multiple time oriented views. This paper addresses problems of the formal definition of relationships among spatiotemporal objects and their properties on geographic information systems. The geographical data are divided in two main classes : geo-objects and geo-fields, which describe discrete and continuous representations of the spatial reality. I study semantics and syntax about the temporal changes of attributes and the relationship roles on geo-objects and non-geo-objects, This result will contribute on the design of object oriented spatiotemporal data model which is distinguishied from the recent geographic information system of the homogeneously anchored spatial objects

  • It was investigated to develop the contents for the local government for the purpose of providing various and correct information. Especially it was focused to take advantage of spatial information techniques, GIS(Geographic Information Systems) and RS(Remote Sensing). The research site for this study was Muan-gun located at the south-western part of Korea, and this site has very high opportunities to became the central point for the economical and tourist industry. The regional information contents for Muan-gun was developed and composed of three elements, internet related, geographic information related and satellite imagery related elements These contents will make a contribution for the local government to present the regional information effectively and efficiently.

  • The National Geographic Information Clearinghouse (NGIC) in Korea has been established to share dispersed geographic information in many government organizations. The NGIC has become a main hub for sharing and exchanging geographic information in Korea. However, due to rapid technological advancement, citizens not only require more information but also demand more functions for NGIC. In this regards, this research tries to find the way of developing NGIC from a means of 'information sharing' to an arena of 'information use'. To do so, it suggests new technical frameworks and functionalities for NGIC. Then it recommend policy measures to improve current NGIC.

  • In 21st century, According to development of Information Technology, It is clear that the importance of tourism information is extended increasingly. For this reason, It should be needed to realize a general system which make it possible to enjoy cyber tourism based on knowledge information system to recover a local potential growth power, catch a jumping chance again, and hold a new competitive power. But to discuss a tourism information system, the matters of hard ware, software and information mediating system should be reviewed generally, this research is likely to provide a cyber tourism information system through internet as a way of cyber tours through multimedia technology and stereoscopic image technique using GIS (Geographic Information System) centering on the networking system of tourism information. Constructing $\ulcorner$cyber touristy city$\lrcorner$ on internet, foster a new industry, to go balanced with a present tourism industry and experience a virtual reality, various theme tours create high profit to shrunken tourism industry.

  • In this paper, we designed and implemented an Internet Geographic Information System, called IGIS, that supports the client/server architecture connected via the Internet. IGIS is consists of the Map Server and the Map Viewer which can be located at a server site and client sites, respectively. In addition, we used the Common Gateway Interface(CGI) to service the geographic information on the Internet and used a DXF(Data eXchange Format) file as a geographic data in IGIS.

  • These days, geographic information system has released in everyday life and industries. However, the shipyard only uses it to manage the layout of the yard. In this study, we apply the Geographic Information System to shipbuilding block logistics simulation to analyse the behavior of bogies and forklifts carrying blocks and materials in the shipyard. The shipyard manages daily block logistics plans at the execution planning stage. However, since it is a daily plan, it is difficult to respond to an unexpected situation immediately, and application to judge a certain value or higher value is insufficient. Therefore, a simulation model was created using the shape and attribute information inherent in the geographic information system to verify and improve the block logistics of the mid-and long-term yards. Through this simulation model, we will analyse loads on the workplace, stockyard, and road, and contribute to overall logistics improvement from the point of view of resource planning. In addition, the results of the simulation are reflected in the planning, to help support various decisions.

  • Recently, GIS(Geographic Information System) has been developed to personalized service for providing the specialized services that is aimed to personal user based on mobile communication. The existing GIS system provides comprehensive and simple information but GIS System for personalized service must provide the adjustive information through the personal interest profile based on POI(PoInt of Interest). This paper describes the intelligent retrieval geographical information service module for providing personal oriented geographic information service. Our proposal model consists of user preference profile, acquisition of POI through hybrid network (Wireless LAN, CDMA), service platform and implementation of prototype system. Implementation model can apply to the life information service like restaurant, oil station, convenient store and etc.
