| Abstract: | The paper mainly introduces how to acquire 3D coordinates of Projection center with precise point positioning,and the method of precise point positioning technologies applied in GPS-supported bundle block adjustment without ground control.With the support of SWDC digital aerial system and the aerial data of Guilin,we do some relevant tests,and the experimental results show that GPS-supported aerotriangulation without ground control can satisfy the small scale cartography. |
