I use Gmap display baidu map & # xff0c; There is no problem & # xff0c; But not a big gap coordinate & # xff0c; According to online to check the data & # xff0c; Baidu said coordinates need to rectify & # xff0c; Add the & # xff0c rectification algorithm; Still a big gap,

such as online zhengzhou coordinates are 21.5053134635657, 67.8822576999664

the actual GPS coordinates are 34.758367, 113.672404

the difference is very big & # xff0c; The algorithm of baidu public is a small deviation & # xff0c; Could you tell me who know is how to calculate the & # xff1f; Thank you & # xff01;

Scott little deviation & # xff0c; But Scott can only display satellite image & # xff0c; Cannot display standard map & # xff0c; According to the detected data changed a few not address & # xff0c; Which know & # xff1f;
