The open data portal collects data created by public institutions and opens and shares them according to related laws. With the activation of the Fourth Industrial Revolution, all sectors of our society are demanding high quality data, but the data required by the industry has not been greatly utilized due to the lack of quantity and quality. Numerous data collected in the real world can be implemented in cyber physical systems to simulate real-world problems, and alternatives to various social issues can be found. There is a limit to being provided. Location intelligence is a technology that enables existing data to be represented in space, enabling new value creation through convergence. In this study, to present location intelligence of open data, we surveyed the status of location information by data in open data portal. As a result, about 60% of the surveyed data had location information and the representative type was address. Appeared. Therefore, by suggesting location intelligence of open data based on address and how to use it, this study aimed to suggest a way that open data can play a role in creating future social data-based industry and policy establishment.

Open data has received a lot of attention from around the world. The Korean government is also making efforts to open government data. However, despite the quantitative increase in public data, the lack of data is still pointed out. This paper proposes a method to improve data sharing and utilization by semantically linking public data. First, we propose a knowledge model for expressing administrative districts and their semantic relationships in Korea. An administrative district is an administrative unit that divides the territory of a nation, which is a unit of politics, according to the purpose of the state administration. The knowledge model of the administrative district defines the structure of the administrative district system and the relationship between administrative units based on the Local Autonomy Act. Second, a knowledge graph of the administrative districts is introduced. As a reference information to link public open data at a semantic level, some characteristics of a knowledge graph of administrative districts and methods for linking heterogeneous public open data and improving data quality are addressed. Finally, some use cases are addressed for interlinking between the knowledge graph of the administrative districts and public open data. In particular, national administrative organisations are interlinked with the knowledge graph, and it demonstrates how the knowledge graph can be utilised for improving data identification and data quality.

Recently, as new paradigm for government operation called government 3.0, government is actively operating policy opening and sharing public data. In addition, the Ministry of Land are operating an open platform integrated map service (the VWorld) which provides a variety of video contents such as the country's national spatial information, traffic information and three-dimensional building for the public. According to W3C Foundation's Open Data Status Report(2013), our country has the evaluated results that the part of the government's policy support and planning is good while the part of the data management is vulnerable. So our country needs the quality improvement for the data management. In addition, a digital aerial photograph image data is required to be up-to-date for the three-dimensional spatial object data. In this paper, we present the method for enhancement of the accuracy of vertical position and for maintainment of up-to-date vertical position. Our methods evaluate the data quality and analyze the cause of error of measurement utilizing the national standard quality assessment method. The result of research shows that the accuracy of vertical position is improved if the height of the building captain is adjusted by the quality assessment values and a three-dimensional model has up-to-date data if reconstruction and extension information of construction register is utilized.

This paper is to evaluate the informational direction, current situations and ERP establishment concerning constructing industry, to present the right directions, implemented cases for implementing constructional ERP, also to suggest the effect, influence, problems and shootings in constructional ERP arena. The constructing industries in korea are facing great turning point because of the huge corruptions currently happened and forcing to open the market in 1997. Attempting to establish Computer Integrated construction system (ERP) by breaking down constructing cost, improving quality, operating rapid and effective construction to enhance productivity, it is hard to achieve the goal with only inter-contractor's establishment. Constructing industries are integrated ones, consisted of many organizations for instance ordering agencies, contractors, subcontractors, material vendors, etc. and use various information formats such as texts, graphics, drawings. I dare suggest that implementation of constructional CALS including EDI/EC, GIS is tile only solution to control the information systematically generated in whole stages from planing, designing, constructing through maintenance, and to supply or switch the information.

Digital library system is an area of multimedia data production system which can differentiate itself from the traditional libraries. While the major role of the traditional libraries is servicing the customers, digital library system is a total system which produces new-formatted knowledge from the existing and new information, and servicing the knowledge to the customers. Thus digital library system must incorporate open and standardized document formats such as SGML, and make the knowledge shareable among the other digital library systems. In order to do show the efficient implementation for the effective digital library system, a technical alternative will be introduced as performing the Digital Library Pilot project.

현재 웹은 단순히 정보를 수집하여 제공하던 웹 1.0을 지나 정보의 사용자가 곧 생산자가 되어 개방된 웹 환경을 기반으로 사용자 스스로 콘텐츠를 제작, 재창조, 공유하는 인터넷 서비스 모델인 웹 2.0으로 발전하였다. 이러한 웹의 발전 과정에서 시맨틱 웹이 등장하게 되었고 시맨틱 웹이 지리 정보와 접목되어 시맨틱 지리 정보 시스템이 등장하게 되었다. 기존 지리 정보 시스템에서는 사용자들이 국한된 정보만을 제공받아 왔지만 웹이 발전하고 수많은 콘텐츠가 생성되면서 웹의 데이터를 지리 정보 시스템과 연결시켜서 사용자에게 풍부한 정보를 제공 할 수 있는 시스템이 연구, 개발되고 있다. 하지만 기존 연구들은 사용자가 시스템에 접속하여 비공간 정보를 입력해야 하는 특정 시스템에 종속적이라는 단점을 가지고 있어 시맨틱 웹에서 지향하는 풍부한 서비스 제공에 어려움을 격고 있다. 따라서 이 논문에서는 웹 자원을 정의된 지리정보 온톨로지(Geo-Ontology)의 인스턴스로 추가하여 지리 정보 시스템의 비공간 정보를 확장함으로써 특정 시스템에 종속적이지 않고 사용자에게 보다 풍부한 서비스를 제공하기 위한 모델을 제안하고 프로토타입을 구현한다.

In this study, it aims to research for unified system of "the surveying and geospatial information management" and new National geoSpatial Information Infrastructure(NSDI) as new paradigm against the strategy of "global geospatial information management". The country's existing NGIS projects and the policies of spatial information were examined in this paper, then it was defined newly by modification of NSDI's data coverage with bottom-up method. The new NSDI strategy is based on large scale digital map which was influenced by the local and global trend such as open data, e-Government, Earth observation, etc. (refer to Fig. 1). It was also suggested with new concept of NSDI model that the public-private sharing data can be added to digital map on equal term with spatial core data. (refer to Fig. 2) It is proposed the institutional model of MOLIT(Ministry of Land, Infrastructure and Transport) as new concept of NSDI which was applied(refer to Fig. 4). The new model is improving localization and reinforcing cooperation system with not only the other departments within the MOLIT but also the other ministries(forestry, environment, agriculture, heritage, etc.) from independent operation system as a part informatization of land, infrastructure and transport. At the new SDI institutional model of the MOLIT, the spatial information is reorganized as common data infrastructure for all applications, Goverment 3.0 can be feasible according to common data related to government agencies and local government's data vertically or horizontally. And then, it can be practical strategy model to integrate and link all the map and the register which are managed by the laws and institutions if this unified system as a common data can include all spatial core data(digital map), such as base map data of NGA(national gespatial agency), land data and facility data of local government.

Recently, Big Data is a buzzword in the creative economy generation. The organizations related to spatial information society focus on building the spatial big data systems. As spatial big data is a combination of spatial information and big data, the data visualization is essential in order to utilize them efficiently. One of the great methodologies for data visualization is infographics. Nationally, Chousn.com initiated the infographics news in 2010. Korean Administration Branches also recognized the importance of infographic and they adopted infographics for their briefings from 2013. Internationally, Visual.ly is leading company in the infographics market and they produced noticeable interactive infographics for Egypt Parliamentary Elections results. In the defense part, Guardian's datajournalism of Afghanistan war log was a good example of utilizing infographics. Throughout the research, five requirements are extracted. First source data should have precision and accuracy in terms of time and space manner. Second, infographics images have a compressibility. Third, the infographics is properly processed for military commanders. Fourth, sharing, openness and communication are essential for high quality infographic. Lastly, infographics should be an analytic tool for predicting future event based on the past data. Infographics is not a direct representation of data but an analytic tool for helping user's choice and decision in critical moments.
