To simultaneously acquire information about the height, reflection intensity, and colors, and to process data that are related to position coordinates obtained by laser measurement.

There are provided a laser sensor 1, a line sensor camera 2, an attitude angle sensor 4, a GPS 5, a control means 21 for controlling the laser sensor 1, the line sensor camera 2, and a scanner 3, a data-recording means 22 for recording measured data, and a data-processing means 23 for processing the measured data. The data processing means 23 performs data processing on aircraft position information 6 by the GPS 5, aircraft oscillation information 7 by the posture angle sensor 4, laser ranging value 8 and reflected intensity information 10 by the laser sensor 1, a scanner scanning angle 9 by the scanner 3, color information 11 by the line sensor camera 2 for superimposing as the information on the coordinates position of a point, where height information 17, the reflection intensity information 10, and the color information 11 are measured.
