As acquisition of the position coordinate data of 2 dimensions or 3 dimensions needs time and labor, recently some real time acquisition of the GIS data using electronic flat board and GPS has been introduced. However, because it is using GPS, there are many problems the system itself is quite expensive, and it is impossible to acquire data in the urban area.
Therefore, to acquire the position data easily and rapidly in the urban area where the data acquisition is difficult, a simple type mobile interface system is developed. It consists of the laser, gyro, electronic compass (the magnetic azimuth sensor) and DGPS. It controls all the data with one personal computer and it acquires data.
