%X The seven-parameter space transformation model can be used to obtain local coordinates from observed WGS84 coordinates.What is the generalized corrective coefficient is described.And the generalized corrective coefficients among parameters of shift,rotation angles,and scale in seven-parameter transformation model are calculated.The high correlations among the seven-parameters are testified when the transformation model is applied to a small region,the feasibility of the seven-parameter model and its equivalence to the there-parameter transformation in a small region are demonstrated.
