The national base map of Korea has become more useful as the spatial information industry has developed rapidly. Beyond the simple application of the past paper map era, the role as important spatial information in the smart city and digital twin era is required with the IT (Information Technology) revolution. Therefore, the concepts of seamless, multi scale, object-oriented, customized production and real-time updating have emerged, and innovations in the distribution process through the internet are also taking place. Although the concept and definition in the law that is corresponds to the status of the national base map must be supported, the concept and definition of the paper map introduced from the surveying law in 1980 still exist. The definition of the national base map cannot meet current technological developments and social needs and does not reflect the perceptions of the majority of the people as well as the practical capacity of government organizations that manage it. Therefore, it is necessary to establish the concept of national base map in accordance with the current situation and to define it in the law. In this study, the concept of national base map was established and defined by comprehensive analysis of the development process of the national base map, the changes in the times and cases of the United States, the United Kingdom and Japan.

As various accidents have occurred in underground spaces, we aim to improve the quality validation standards and methods as specified in the Regulations on Producing Integrated Map of Underground Spaces devised by the Ministry of Land, Infrastructure and Transport of the Republic of Korea for a high-quality integrated map of underground spaces. Specifically, we propose measures to improve the quality assurance of pipeline-type underground facilities, the so-called life lines given their importance for citizens' daily activities and their highest risk of accident among the 16 types of underground facilities. After implementing quality validation software based on the developed quality validation standards, the adequacy of the validation standards was demonstrated by testing using data from two-dimensional water supply facilities in some areas of Busan, Korea. This paper has great significance in that it has laid the foundation for reducing the time and manpower required for data quality inspection and improving data quality reliability by improving current quality validation standards and developing technologies that can automatically extract errors through software.

In this paper, we examined how to utilize QR codes for meeting the information demand and making better use of the paper map. By Decision Tree Analysis, we investigated whether to have any intention to use the paper map with QR codes for receiving more information and what decision variables affect the answers. Thus, we also surveyed the area of providing information and sectoral demand for deriving additional information demand to being provided through QR codes. In the results of our study, we confirmed that the decision variables, to make any intention to use the paper map with QR code, are the frequency of using the paper, the experience of using the paper map, the intention to buy the paper map, the experience of using QR codes and the experience of buying the paper map. In these variables, the frequency of using the paper map is a major factor to decide whether it is intended to use the paper map with QR codes. we also identified that there are various additional information demand using the paper map with QR codes in the area of 'Daily life', 'Real estate', 'Education', 'Travel and Leisure', and 'Entertainment'. Especially additional information demand is high in the area of 'Travel and Leisure'. These results could be used to find a way how to vitalize the usage of paper map by introduction of QR codes and how to develop QR codes for the paper map and concerning applications.

Recently, demand for the use of cadastral map is increasing in both public and private area. To use cadastral map in web or mobile environment, construction of the multi-representation database(MRDB) that is the compressed into multiple scale from the original map data is recommended. In this study, the map generalization methodology for the cadastral map by applying overlay with topographic map and polygon generalization technique is suggested. This process is composed of three steps, re-constructing the network data of topographic map, polygon merging of parcel lines according to network degree, and applying line simplification techniques. Proposed methodologies are applied to the cadastral map in Suwon area. The result map was generalized into 1:5,000, 1:20,000, 1:100,000 scale, and data compression ratio was shown in 15% 8% 1% level respectively.

Nowadays, digital map plays a role as a container of spatial database.'there have been many researches concerning the improvements of the digital map accuracy. From the user's viewpoint, however, the quality level of digital nap is as important as its accuracy, because fitness-for-use is considered the most important factor to the users. This study aims to find the methodology for determining the grade nか digital map. To accomplish this, we propose two major stages. First, weight factors of the layers are given according to the importance of the functions which must be considered in digital map generation. Scond, weight factors of the components to evaluate the accuracy of the digital map are presented By scoring the components and by summing the scores, the method for determining fitness-for-use is developed.

To construct road spatial information database, it is the main object of this study that an analysis of road factors and furthermore this is used to the rescue activities in case of urban disasters. When urban disasters such as earthquake or explosion cause fire and collapses people of the affected region happen to evacuate. But only to manage roads and monitor traffic volume, the road data is designed and managed using digital topographic map so it is short that the design of road spatial data to prevent disasters. In this study, we tried to suggest the evaluative factors of evacuation to design database : road width, traffic volume, the fixed or movable obstacles installed, the surrounding environments that dominate the land-use planning, the uses, materials, structures, sizes, and densities of the buildings. Thus, these could provide fundamental data to determine the disasters management planning for evacuation and rescue activities, to evaluate the riskiness, and to draw up hazard information map.

The integrated underground space map is a three-dimensional map that integrates 16 types, including 7 types of underground facilities, 6 types of underground structures, and 3 types of ground. In order to systematically construct, manage, and utilize the integrated underground space map, it was institutionalized as the "Special Act on Underground Safety Management," and the "Underground Space Integrated Map Production Work Regulations" was prepared as detailed work regulations. However, there is a lack of institutional mechanisms to develop new technologies such as the completed book submission system for submitting change information and automation technology for updating the integrated underground spatial map and to expand the usability of the integrated underground spatial map. Accordingly, this study examined the current status of the integrated underground space map and attempted to suggest a direction for improving the current system through a revision plan and detailed operation management regulations (draft) of the Special Act on Underground Safety Management.

This paper designs and implements an integrated map server to produce an integrated map. Two requirements for the proposed map server are as follows. First, the system should support a customization of metadata to meet user's requirements. The map server designed here will predefine information such as representations, regions required for client-side processing in the metadata. This will allow users easily acquire an integrated map in the required form of clients. Second, the system should be able to support not only the integration of spatial data but also their non-spatial data. Fusion service is realized by using the concept of linking. The integrated map server suggested in this paper can improve the quality of the fusion service by integrating the results of the map servers according to user's requests. Our experiments shows that the integrated map server reduces the response time in web mapping environments.

A study about UFID for the management and administration of digital map has achieved much progress through the Korea National Geographic Information Institute. But it is ture that the content and process is too complicated to be applied. For overcoming this and to make harmonious management of the object based seamless digital map, we need to develop the method which has the unique feature identifier on the digital map for management and administration. So, we introduce OSID(Object-based Seamless digital map IDentifier) on the object based seamless digital map and apply OSID in the system to manage the digital map. This study is based on the OSID basic structure which is applied in object based seamless digital map and design the structure of OSID system to maintain and manage each feature of the object based seamless digital map.

Map is information media for human life. Recently, innovative map making technology has been developed and most updated various data are provided to map users. In consequence, use of maps is rapidly increasing in various applications. One of the examples is car navigation map because navigation maps provide reliable and necessary information with convenient way. Therefore, maps are to be changed to user-oriented from map making-oriented design. The main goal of spatial data infrastructure is to allow various users to access the real world information easily for decision making. However, most of the digital maps are focused on map making aspect such as providing up-to-date data, acquisition of accurate data with state-of-the-art technology, and addition of layers (For example, ortho-images and DEMs). If map data processing tools are to be provided with the digital maps, users could utilize maps for decision making without professional software or knowledge. Therefore, objective of this paper is to propose scheme of the digital map data processing service with application examples.
