According to the difficulties to use early small scale aerial photos in large scale digital mapping,the paper discusses the technique of precision control with an example of using 1∶ 60 000 aerial photographs to make 1∶ 10 000 maps.By checking up the mean square error of plane,elevation and distance between object points of the digital product,the paper proves that the precision with early small scale aerial photos to draw big scale digital production meets the demand of criterion very well.
