Development of Simple Updating System for Digital Maps Hiromichi Maruyama, K. Ishida, N. Kubo, S. Odagiri Geographical Survey Institute, Ministry of Construction Kitasato-1, Tsukuba-City, Ibaraki-Pref., Japan 305 ABSTRACT Digital maps are very important as the basic information of Geographic Information System, and should be updated as frequent as possible. However, conventional method using stereo plotter and stereo photographs takes much time for updating and requires skillful operators. Therefore, in cooperation with companies, we developed the simple updating system in which scanned digital aerial photograph is overlaid on digital map to be updated and an operator finds and updates the changed parts on the computer display. This system does not require special photogrammetric instruments but common workstation and its peripherals, such as scanner, cartridge disk drive and color hard copy, and as the stereoscopic viewing is not required, anyone can handle it easily. KEY WORDS: Map revision, Digital aerial photograph, Digital map |. INTRODUCTION Maps should be revised according to the changes of earth such as the construction of new roads, buildings or the development of golf links. So far, when map revision 1s conducted, geometric accuracy has been mainly stressed on. Therefore three dimensional measurement using stereoplotter, which requires the special instruments, skillful operator, 1s applied for map revision. Recently, the digital maps have come to be often generated and used in the GIS environment. This means, in order to increase the reliability of the results of analysis of the GIS operations such as the extractions of some map features or the overlay with other layers, the contents of map should be coincide with real situation more than before. Based on these backgrounds, simple updating System for digital maps, which does not require special instruments and enable anyone to revise maps if digitized aerial photograph are available, has been developed by the surface 405 cooperative work between Geographical Survey Institute (GSI) and companies. In the following, the basic design of updating system is summarized and the system designed for 1:25,000 scale map, which has been developed by GSI, and the system for 1:2,500 scale map, which has developed by companies, are described. 2. SYSTEM OVERVIEW Simple updating system should be the system by which anyone can revise digital map easily. In order to attain this concept, the measurement by stereoscopic view should not be used and the extraction of changed parts should be able to be done easily. Therefore, in this system maps are revised manually using mouse after single digital photograph 1s overlaid on the digital map to be revised and the changed parts are recognized visually. Figure 1 shows typical hardware configuration of simple updating system.
