Abstract
The facility area occupies approximately 50% of the topographic landmarks playing an important role in the utilization of geographical information in various fields, and requires more up-to-date information than the framework data of other areas. However, the expression mode in the 1:5000 digital map, which is a primitive data used for the preparation of framework data in the facility area, limits the description of the information on buildings, and its revision/renewal term of 5 years makes it far from up-to-date or accurate. Therefore, this study aimed to analyze the problems and quality deteriorating factors that may occur in establishing the framework data on the basis of existing establishment process of them in the facility area, and improve the qualify of the framework data in facility area by upgrading the methods of quality improvement. Expanding the information on attributes and improving the accuracy of locations were proposed as ways to increase the degree of utilization of the framework data in the facility area. And as the methods of expanding the information on attributes, it was proposed to improve the accuracy of the information on attributes for the framework data in the facility area using the information on attributes in the 1:1000 scale maps, and also to diversify the information on attributes in connection with the LMIS and AIS. To improve the accuracy of the locations, analyses were made with the potential problems that may occur in the establishment process through an experiment on the framework data in the facility area based on 1:1,000 digital map, and the results were used to present an improved, optimum process.
