  • This paper deals with the building of road facility management system lot the efficient and scientific management of road infrastructure by making use of Database with a variety of biridge and tunnel - related informations such as maps, registers and documents(graphical and nongraphical data). The main objectives of the creating of the Database are the rational maintenance planning for facilities and the systematization of information management through the fast updating, mending and supplement. Some actual data sourced from the administrative office could be tested in order to validate this road facility management system and we could acquire many valuable results. Therefore we can expect to play an important role of results in the practical use for the management of the various md facilities.

  • In a route plan, the route selection is a complicated problem to consider the spatial distribution and influence through overall related data and objective analysis on the social, economic and technical condition. The developed system in this study was compared and estimated by deciding a practical section for its validity and efficiency. Using Geographic Information System (GIS), the various information required for route selections in database was constructed, the characteristics of subject area by executing three-dimensional terrain analysis was grasped effectively, and the control point through buffering, overlay and location operation was extracted. An optimum route was selected by calculating the sum of alternatives to the sub-criteria weight, and from this result, there is a difference between real route and proposed route according to the prioritization of decision criteria based on the importance. This research could be constructed and applied geospatial information to the reasonable route plan and an optimum route selection efficiently using GIS. Therefore, the applications are presented by applying Analytic Hierarchy Process (AHP) to the decision-making of information needed in route selection.

  • Domestic 2D maps includes only most up-to-date information at the time of production without historical information. Therefore, it is hard to identify the change history of real world objects. In this research, Spatio-temporal model for 2D map were developed and it's compatibility was verified through the pilot project conducted on the Gwanggyo area of Gyeonggi province. Also, the procedure to generate 2D spatio-temporal database using maps made periodically on the same target area was introduced for showing the possibility of realizing nation wide spatio-temporal 2D map using the national base map updated periodically.

  • In these days, the attributes data recorded in computerization of cadastral maps is just written in its own format, not considered the relation with graphic data. Therefore, digital information linked attribute data to graphic data is necessary to be performed as fundamental data of graphic information and analysis of various spatial information. This study is to present the possibility of GIS application by constructing cadastral information related to graphic and attribute Information based on the cadastral map. Attribute information was constructed as a relational database form using data modeling and entity-relationship diagram. Thus, this study is expected to be used as a fundamental data for various public planning and design including the effective management of cadastral information and building parcel based land information system by presenting various spatial analysis and application methods.

  • The aim of this paper is to come up with a methodology of constructing an efficient model for multiple representations which can manage and reconcile real-time data about large-scale roads in Vector Domain. In other words, we suggested framework based on a bottom-up approach, which is allowed to integrate data from the network of the lowest level sequentially and perform automated matching in order to produce variable-scale map. Finally, we applied designed multi-LoD model to in-vehicle application.

  • As social demands on forest are diversified, we need some economic and pro-environmental methods of forest management. In this study, developing an FMS(Forest Management System) using GIS techniques, we aimed at making workers handle quickly and exactly their works related to forest, offering customers the exact information and making clients modify or renew the variously changing information about forest. Therefore, we can efficiently handle the works related to forest management. For this, we designed and developed the system to be in accord with working-level and we can handle various information efficiently and conveniently. Accordingly we can process and print out data based on each subject. In addition to that, we can preserve the consistency of data by connecting work zones and providing database through network.

  • Efficient representation is crucial in the analysis of complex geospatial information. In case of aerial triangulation, most of currently available software are designed as black boxes where only an experienced user would be able to prepares the preformatted input file and interprete the result of the adjustment. This paper introduces a solution to this problem through the UML design of a Graphical User Interface (GUI) for the aerial triangulation task. The design was then implemented with ArcGIS. The error of the exterior orientation of each aerial Imagery was represented with a 3-D error ellipse, enabling the visualization of the adjustment result. The attributes of images and points (control points, tie points and image points) were maintained as a database which enables the searching and querying of adjustment information.

  • Until now, The our concept about a national geospatial data infrastructure have been concentrated on a field of producer. This concept is the trend which the focus have been inverted currently with the use to process data in an user viewpoint and to the compatibility of the database. But the standard of our national framework data is defective yet. Also, The law and policy are not clear and the concept recognition of users lacks. This paper is showed improvement plan of development and maintenance of the national framework data, and researched the relationship between the national framework data.

  • This paper refers and implements XML Web services, which supports networked interchanges of moving object information. XML Web services are expected to be fundamental building blocks in the move to distributed computing on the Internet. As an interchange format, GML encodes semantics, syntax, and schema of geospatial and geoprocessing-related information resources. It can give great benefits to utilize raw data easily as an XML encoding format does. This paper proposes a full coverage of interoperable location trajectory services consisting of 3 independent modules: a moving object database, a data processing server, and a web services interface module. For communications, SOAP protocols and WSDL documents are used, which can guarantee an interoperability of a system regardless of different platforms and service channels. This paper also designs a GML data format that represents location information of probe cars.
