The purpose of national land information system is to establish information management system that systemizes all information related to the national land. Thus, integration system as computer program is necessary in order to automatically process data and information that are utilized as information sources of national land in the future.
In this process, integration or institutional systemization of information related to national land should be preceded.
First, legal and institutional basis for national land integration information structure and use should be established and revised. In other words, institutional base that is the basis of national land integration information structure and use is required. Thus, relevant laws and policies should be revised for the effective integration of national land integration information. Legalization of national land information law is necessary for integrating laws relevant to national land including fundamental law of national land.
Second, it is necessary to construct metadata of national land information for integration․connection of national land information that has been constructed by parts such as national land information, land information, mountain, farmland, cultural heritage, environment, real estate registration, and measurement and to maximize synergy effect of data or system use through use of necessary information with metadata and connection of information system to each part.
Third, integration of administrative organization is necessary for operation of national land information integration system. In other words, in order to maximize the efficiency of integration of national land information, an organization that is responsible for planning and adjusting national land information should be established, and the role administrative organization should be strengthened. Detailed and realistic execution plans such as execution of step-by-step plan of data connection and information integration, advancement of national land integration information contents, establishment of standard system of national land information, mutually cooperative upgrade of national land information, sharing direction and road map of infrastructure establishment for administration organizations, and securing continuous budget support.
Fourth, the center of structure of information system should be shifted from supplier to consumer. Demand of national land integration information should be analyzed by the perspective of consumers, and the range of public national land information such as private information protection and security information needs to be expanded. In order to provide One-Stop service on national land integration information to the people wherever and whenever, national land integration information portal, which is infrastructure that takes the role of hub and window for national land integration information, should be established. Thus, integration information portal should provide real-time information, regulation procedures, regulation guidelines, and various national land information through internet and become an open portal that enables consultation, connection inquiry, and administration participation.
Fifth, in order for synthetic use of national land information, the balance of national land information is required in various perspectives such as underground and above ground, land and ocean, and real national land and cyber national land. Also, higher level demand for national land information for public and private should be met by applying national land information project to cyber national land. Through promotion of information-oriented real national land and construction of cyber national land, national competitiveness and productivity should be improved and 'digital integration national land' should be pursued to promote convenience of life for the people.
In conclusion, institutional and systematic support should be expanded through national land information integration based system in order to maintain precise, updated, unified, and consistent national land information.
Especially, advanced national land information policy is required for high quality and realistic national land information service. When considering change in information technology and competition among countries, it will be an essential task to propose visions and strategies appropriate for international environment change in order to continuously maintain internationally highest level of national land information and, consequently, to establish national land information system to strengthen national competitiveness.
