| Abstract: | The selection of a city coordinate system of the plane control network must be satisfied with the deformation of projective lenth to be not bigger zhan 2 5cm/km,thus it is easy for the large-scale mapping of a city and the construction lofting of municipal engineering. From the beginning with changing the central meridian line and the projective plane, the paper analyzes the selection of the coordinate system of the plane control network in shijiazhuang city. |

| Keywords: | central meridian line projective plane reduced height height of compensative plane |
