The conversion between Baidu latitude and longitude (BD-09) and Google latitude and longitude (WGS-84) requires certain conversion operations. Here are brief instructions for converting from Baidu latitude and longitude to Google latitude and longitude and from Google latitude and longitude to Baidu latitude and longitude:
Conversion from Baidu latitude and longitude (BD-09) to Google latitude and longitude (WGS-84):
Baidu latitude and longitude (BD-09) is an encrypted coordinate system, which needs to be decrypted into Baidu coordinates (BD-09) first.
Then, use a conversion algorithm to convert Baidu coordinates (BD-09) to Mars coordinates (GCJ-02).
Finally, convert Mars coordinates (GCJ-02) to Google latitude-longitude (WGS-84) coordinates.
Conversion from Google latitude and longitude (WGS-84) to Baidu latitude and longitude (BD-09):
First, convert the Google latitude-longitude (WGS-84) coordinates to Mars coordinates (GCJ-02).
Then, convert Mars coordinates (GCJ-02) to Baidu coordinates (BD-09).
Please note that these conversion processes require the use of specific algorithms and mathematical models, and due to differences between coordinate systems, there may be certain errors in the conversion results.
For specific coordinate conversion operations, you can use some open source geographic information toolkits or online services, such as coordtransform (Python library) or the coordinate conversion API of Baidu Maps Open Platform, to achieve mutual conversion between latitude and longitude. These toolkits and services can provide more accurate and convenient coordinate transformation functions.
