CONSTITUTION: An image searching unit searches a related aerial image in a data storage module based on a keyword. An image output unit outputs a searched image. A user moves an image. An image identifying unit identifies an image of a predetermined structure on the ground. An image tracking unit traces the position of a confirmed structure or a reference point. If an image of a specific structure is out of a border portion, an image output outputs the border portion and the linked neighbor image.
