This paper show about the possibility of practical application after building VR(virtual reality) data based on Airborne LiDAR data which determines complicated topography quickly for the 3D-GIS construction. In this paper, we collected Airborne LiDAR data, digital map, serial photo and a basic design. The results are expected some effective determination by 3D-GIS construction based on LiDAR data. Hereafter, because the research will be able to be given quickly topography information on ubiquitous environment the field of construction and GIS will be able to be helped.

Recently, E-Commerce demands an integrated solution for online and off-line provided to customers on wired / wireless network and various mobile devices. Our E-commerce platform can use anytime, anywhere, for all consumers. And, it can take convenient and secure E-commerce service in mobile environment. So, we will implement a software platform base on the mobile environment that independent of the mobile OS. Particularly, our E-commerce platform is based on 3D GIS information for 3D electronic map. So, all users (customers) have got the more visible convenience. And, by using the e-catalog DB cloud server, off-line store operators can be built the online home-page easily. From now on our E-commerce platform based on 3D GIS can be usable at various E-commerce areas in the ubiquitous environment.

In this paper, an rice intake management system based on ubiquitous computing technology is introduced for rice processing complex (RPC). This system plays an important role in the quality management for rough rices in that the system provides timely and useful information of rice cultivation. The intake management system is developed by utilizing widespread ubiquitous technologies, such as smartphones, GIS and LBS, for the purpose of controling the harvest time and monitoring the quality of paddy. The information for rice production, cultivation and quality management is transmitted and stored in a centralized database via mobile networks, On the basis of these information, the harvest schedule is determined and notified to farmers though smart devices. Hence, the proposed system can help to establish trust among farmers, operators and consumers by providing systematic information based on ubiquitous computing technology.

In ubiquitous computing GIS services, it is possible to use the spatio-temporal data anytime through the mobile device. GIS services regularly update use the latest spatio-temporal data to provide the most suitable services. For this situation, update data is distributed to CD or wired networks update services. However, this method has problem to propagate update data to users as taking long time. In this paper, suggests a synchronization system which propagate update data to users for reducing processing time efficiently. This synchronization system collects update data in the field and synchronizes server with collected data to use mobile devices by real time. For this system, I design and materialize synchronization module which updates update data and wireless network module.

With the advent of u-City(ubiquitous city) concept, the importance of urban management has been increased. GIS is a foundation for the efficient urban management and an essential technology for the development of u-City. u-City, which aims for convenient, safe, healthy, and comfortable life, provides diverse services based on advanced information technologies, and it will offer more services in the future. u-City integrated management platform enables the ease of service development, guarantees the quality of services for the resident, and provides organic information sharing. Moreover, the platform by integrating GIS and other common management functions, makes possible efficient urban management. In this paper, required functions of u-City integrated management platform for u-City service were analyzed. As a result, GIS module for management of street lights and supervision of fire was developed and the application usability of u-City integrated management platform was verified by service simulation.

There is not enough knowledge on how to use, build, and apply ubiquitous technologies such as the ubiquitous sensor network, GIS, statistic analysis system, mobile GPS system etc. Also there are other questions such as, how should the knowledge information resources be managed and web decision making system developed for national park management. The purpose of this study is to propose a framework for the national park integrated management system based on ubiquitous information technology. This study will include followings: 1) this study explores what ubiquitous information technologies are needed for national park management, 2) this study proposes building strategies about the spatial and attribute database using ubiquitous information technologies, and links methods among geographic information system, analysis program, sensor network, etc. The results of this study will contribute towards deciding a direction for national park policy in preparation for the ubiquitous computing oriented society.

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.
