| Abstract: | It mainly validates the influence of ellipsoidal height on grid frame and height in coordinate transformation, which provides the available basis for application of the actual construction projects. It provides two sets of transformation parameter through altering the ellipsoidal height of the points selected and then compares the two sets of gauss coordinate obtained from the two sets of transformation parameter. The conclusion is drawn through the data tests on different ways. |
