Transformation Methodology: BD09 to WGS84
Converting BD09 coordinates to WGS84 involves reversing Baidu's proprietary transformations, decrypting China's official coordinate encryption, and applying precise mathematical corrections to restore coordinates to their original global geographic positions.
WGS84 = Reverse_Transform(Decrypt(BD09_Coordinate))This sophisticated transformation process mathematically reverses the dual-layer modifications applied in BD09, first removing Baidu's projection adjustments, then decrypting China's official coordinate encryption to recover the original WGS84 geographic positions.
