Usually in South Korea, land cover type and topographic undulation are frequently changed even in a narrow area. However, most of researches using aerial LIDAR(LIght Detection And Ranging) data in abroad had been acquired in the study areas to be changed infrequently. This research was performed to explore reconstruction methodologies of 3D surface models considering the distribution of land cover type and topographic undulation. Composed of variously undulatory forests, rocky river beds and man-made land cover such as streets, trees, buildings, parking lots and so on, an area was selected for the research. First of all, the area was divided into three zones based on land cover type and topographic undulation using its aerial ortho-photo. Then, aerial LIDAR data was clipped by each zone and different 3D modeling processes were applied to each clipped data before integration of each models and reconstruction of overall model. These kinds of processes might be effectively applied to landscape management, forest inventory and digital map composition. Besides, they would be useful to resolve less- or over-extracted problems caused by simple rectangle zoning when an usual data processing of aerial LIDAR.

At present, the cadastral field, with the conversion into digital cadastral map management system, not the existing cadastral map management system, has gone through a lot of changes, such as the market opening of cadastral surveying and overseas launching of a cadastral field. Such an environmental change has brought on a lot of advantages, such as improvement in accuracy of surveying, efficient management system, and reinforcement of competitive power in cadastral surveying. However, the conversion into the advanced cadastral management system serves to relatively heightening the possibility of outflow of cadastral information and its technology in comparison with in the past. This research, with the aim to cope with indiscriminate outflow of cadastral technology, is aimed at suggesting the plan for the prevention of outflow of cadastral technique and its protection after examining and considering the contents of environmental changes in the currently going cadastral field.

Recently, development and research of u-City established the ubiquitous environment which can be anytime, anywhere computing or network, has been much highlighted. Thus, current urban facilities should be managed by ubiquitous concept, and monitored location and status information in a real-time manner, and controled if necessary. In order to be establish in the purpose of management, indirect mapping through id-tag is better than facility management directly. For instance, RFID, UCODE, UFID. In this paper, we propose that represent facility object through UOID(Unique Object IDentification). UOID comprises three parts; 1) sensing object, 2) facility object, 3) cell object consists of facilities. and Life cycle management system in UOID, and network system connected with internet is proposed. We wish that proposed UOID and network system mange u-City facilities effectively, and also provide ubiquitous service to the citizen, one of the integrate service of u-City platform.
A System of Guiding Path for Parking Lots based on RFID to Consider Real-time Constraints

Journal of Korea Spatial Information Society, volume 16, issue 1, 2008, Pages 65~77
There have been many studies and technologies that define a current location of a moving vehicle with GPS(Global Positioning System). However, the navigation system with GPS has troubles to search an optimized route considering data such as realtime parking status and road conditions. Moreover, the GPS systems show malfunction in the downtown with very tall buildings, underground parking lot and the inside of buildings. On the contrary, the RFID systems are able to reflect real-time status of parking lots and roads in the downtown. This paper proposes a system of guiding path for parking lots to consider real-time constraints based on RFID. The results obtained from the implemented system show smooth guiding of a new route after immediately sensoring the change of the information of parking lots and roads: if a parking lot that a vehicle is heading to is fully occupied, the system re-searches a new route for a neighbor parking lot and immediately transfers it to customer's mobile, and if the designated route is under construction, the system guides a detour path. The proposed method will be useful for advanced integrated parking control system.
Strategic Plan for Improvement of Citizen Service using Ubiquitous Technology on Public Area: Geospatial Web based Service
Kang, Young-Ok ; Kim, Hee-Won ;
Journal of Korea Spatial Information Society, volume 16, issue 1, 2008, Pages 79~99
Enterprises as well as central and local governments have tried to apply ubiquitous technology to the actual life on the various types of business and projects. In this paper we develop strategic plan to provide public service on public areas based on needs analysis of public services as well as trend analysis of ubiquitous and web technology. Ubiquitous service model should be based on geospatial web which can incorporate participation and collaboration concepts, as the wire/wireless network system develop rapidly. To achieve this purpose, we suggest the following projects; 1), construction of internet map based on geospatial web technology, 2), development of web contents based on geospatial web, 3), installing ubiquitous equipment, and 4), upgrade Seoul Metropolitan Government's homepage and internet system which can incorporate web 2.0 concepts. Ubiquitous service model should be based on not only development of ubiquitous technology but also needs of consumer such as citizen, enterprises, and public sectors which have an interest in that place. Geospatial web will be the core of development of ubiquitous service models.

Journal of Korea Spatial Information Society, volume 16, issue 1, 2008, Pages 101~112
This study aims to show why we have to introduce SOA paradigm in the Cadastral Information System for coping with domestic and foreign IT environments flexibly and strengthening inner capability. We search the trend of up-to-date IT paradigm such as Enterprise GIS, SOA and etc. from this, we worked out the concept of Cadastral Information System. we also could see the introduction case of the domestic and foreign next generation Cadastral Information System, there is implications for us. also, we analysis the general condition about information system which KCSC(Korea Cadastral Survey Corporation) own in a general way and estimate the SOA level degree for each information system. and on that base, we set up SOA loadmap for implementation the next generation of Cadastral Information Service. This is an important step for building ideal future information systems which KCSC hope to be. For realizing this, we focus our inner capability on integration without duplicate and re-using the inner information infra.
Efficient Spatial Index for Mobile Software
Oh, Byoung-Woo ;
Journal of Korea Spatial Information Society, volume 16, issue 1, 2008, Pages 113~127
This paper proposes an efficient spatial index, named
-tree) which is a variant of the
-tree, for mobile software. A MBR(Minimum Bounding Rectangle) structure of the
-tree has additional min and max values of area axis as well as x and y axes. The value of area axis is used to determine the significance of a spatial data. If area of a spatial data is large, then it is significant when drawing a map. To reduce complexity of a map on a small screen of mobile device, only significant spatial data can be found by the
-tree. The result of a series of tests indicates that the
-tree provides a method for control of readability of a map and guarantees an efficient performance at the same time.

Journal of Korea Spatial Information Society, volume 16, issue 1, 2008, Pages 129~144
The Act on Ubiquitous City Construction and etc.
was approved by the National Assembly. The law stipulates the regulations on the planning, construction and management of the Ubiquitous City. As its national-level law system is about to take its effects, future new city developments are expected to have its legal basis to be built to meet ubiquitous city requirements. Also, it is anticipated that such needs would require much more planning techniques and strategies. In reaction to those upcoming needs, this study is to search for new planning approaches to realize the u-City in reality. It is also to supply with the framework to execute the u-City projects in more structuralize and systemize manner. Therefore, with the purpose of the establishment of comprehensive planning system, the theoretical bases were sought in relation to planning u-City, pre-existing u-City development cases and regarding regulations were analyzed, and then basic concepts, features, and constituent factors were set up.
A Study on the Research Methodologies of Geographic Information System and Utility of Case Study Method
Kim, Tae-Jin ;
Journal of Korea Spatial Information Society, volume 16, issue 1, 2008, Pages 145~155
Case study has been criticized far its lack of generalization to the larger population and lack of sampling controls. Some of shortcomings of case study methods may be overcome, by using logically consistent, rigorous, and systematic approaches. Especially, Case study method has been suggested as appropriate for researching a range of GIS implementation, utilization, and diffusion issues. This paper provides examples of how the substance of its requirements may be met in the context of GIS case study. For the successful implementation of GIS, this study suggest that the case study method in GIS appropriate to the study of casual relations in and explication of complex GIS acquisition and adoption process.
