It is restricted on CPU ability, memory, display size and networking to process GIS data on ubiquitous-based terminal. For that reason, we tried to improve the cadastral electronic file to solve these problems in this paper. The format of old cadastral electronic files is not efficient because it is made of file structure. So, it has inconvenience to let us read whole file, displaying on the screen and connecting to geographic objects by adding index file like database for connecting to geographic object and displaying on the screen. The file size was decreased to 27.6% of original file size through converting format.
