Description: This procedure provides the WGS - 84, BJ54 and Xi 'an80 geodetic coordinates, the space rectangular coordinate and gaussian coordinates transformation, under different parameters of ellipsoid transformation through the space rectangular coordinate transition, due to time reasons, only under the BJ54 gaussian coordinates and calculate. The conversion of spatial coordinates requires the use of seven parameters, which can be manually entered, and can also be computed by at least the common point adjustment in the text file (data.txt can be used for seven-parameter calculation test).
Calculation process:
Wgs-84 B=30.303622 L=114.212196 H =47.36
(the latitude and longitude are written in seconds)
BLH - & gt; XYZ = 2268156.8016 X Y Z = 5010324.6053 = 3219239.5885
XYZ WGS - 84 - & gt; BJ54 XYZ (the parameter is set to 0, unchanged)
BJ54 XYZ - & gt; BLH B =30.303614 L=114.212196 H= -61.3351
BLH - & gt; XyH x=3376768.6854 y=534182.3886 H unchanged
(for the sake of convenience, there is no projection band in front of y, which is known as 38, or y= 38534182.3886).
