PURPOSE: A data measuring system using aviation images for a road register is provided to minimize the usage of facilities on the road, thereby minimizing the inconvenience to pedestrians and drivers. CONSTITUTION: A data measuring system using aviation images for a road register comprises a transmitter(40), a camera(50), a memory(60), and an indicator(1). The transmitter is installed in an airplane(30) and transmits photography starting signals and photography completion signals to the ground. The camera is installed in the airplane, thereby photographing the ground where roads are installed. The memory records the data of aviation images photographed by the camera. The indicator is installed in a street sign(20) so that a direction board(22) of the street sign is displayed horizontally in the aviation images photographed by the camera. The street sign is composed of a horizontal bar(21) and the direction board. The horizontal bar is installed to be protruded in the upper later side of a pillar(10) installed around the road.
