The present invention relates to a generation system using a method for generating image coordinate information of a specific facility according to city planning information. The generation system includes an observation satellite part for collecting image information and coordinate information about observation area; a coordinate information display part which generates grid image coordinate information by receiving the collected image information and the collected coordinate information, and displays the image coordinate information in three dimension; a portable terminal which stores image coordinate information, and analyzes and stores error according to the difference between the image coordinate information and city planning information; and a city planning information database which stores a cadastral map including geographic information of a city, building layout, building design drawing and city planning information to provide for the observation satellite part, the coordinate information display part and the portable terminal. The generation system provides coordinate information of high reliability for a user by collecting and analyzing image information and coordinate information about the specific facility and area. The generation system enables the user to check progress status of the city planning information visually by simulating and displaying the image coordinate information. The generation system enables the user to read additional information about the specific facility anytime through a touch display, and thus enables the user to make more analytic city planning information.
