The difference between Urumqi 95 coordinate system and Urumqi 200 coordinate system

The elevation of coordinate system 95 is the same as that of coordinate system 2, and there is no difference, because the national elevation datum of 1985 is used uniformly throughout the country.

There is no 95 coordinate system, only 84 coordinate system and geodetic 2 coordinate system, so there is no way to convert 2 into 95.

2 coordinate system definition

Origin: the center of mass of the whole earth, including ocean and atmosphere;

Z axis: the direction from the origin to the earth reference pole of epoch 2.

X axis: from the origin to the intersection of Greenwich reference meridian and equatorial plane (epoch 2. );

Y axis: forms a right-hand orthogonal coordinate system with Z axis and X axis.
