摘要： PROBLEM TO BE SOLVED: To automatically recognize a specific drawing element from overall drawings and to automatically input each position and attribute by preliminarily storing the attributes of a drawing element and the regulation and condition of arrangement. SOLUTION: A drawing data inputting means 2 inputs the data of a desired drawing 6 and it is shown on a screen of a displaying part 5. When a manual operating part 3 designates a range where a drawing element that is an origin of a system exists on the display, a controlling part 1 executes a program that searches a shape that is preliminarily designated to a specification range and detects the drawing element. Further, it takes information about attributes of the drawing element from a database 4 and then, automatically specifies a range on the drawing which is considered to include other drawing elements based on attributes of the detected drawing element and the regulation and condition of drawing element arrangement. When all of the drawing elements on a display screen are detected in this way, the part 1 shows these detected drawing elements as a system on the part 5.

摘要： PROBLEM TO BE SOLVED: To adapt plural maps with high accuracy by simple computation and to obtain the coordinate information of the arbitrary map by assigning two points corresponding to the assigned point of the first map with the second map and correcting errors occurring in the mispositioning of both maps, map scales, a difference in vertical and longitudinal proportion ratios, etc. SOLUTION: The two points on the first map are first determined (step S1) and in succession, the two points corresponding to the second map are selected (step S2). The absolute coordinates of the first map are then calculated from the absolute coordinates at the two points on the second map (step S3). Next, the distortion correction parameters for the errors of the mispositioning of the maps, inclination of horizontal lines, the map scales, the difference in the vertical and longitudinal proportion ratios, etc., are calculated (step S4). The exact absolute coordinates on the arbitrary point on the second map are determined from the relative coordinates on the map by using these parameters (step S5). The easy calculation is thus made possible even if the angle of the first assigned points or second assigned points of the first and second maps to the horizontal axis is 90 deg..
