But in some cities or large engineering construction may be just on the border of two projection zone, setting control network if according to the standard of 3 degrees 1.5 degrees or with projection, projective deformation will be very big, to inconvenience construction work, the need to establish local independent coordinate system. Meet national coordinate system transformation and the local independent coordinate system has certain practical significance, how to realize the conversion of the two, has been a hotspot problem in engineering construction. Therefore, complete engineering field state coordinates measurement results and achievements of local independent coordinate transformation problem, to meet the needs of the urbanization and the actual engineering.
