Map offset in China
Hi. I'm in China. I want to use the Open Street Map Android app to grab Lat and Long point data and then drop that data into a Google Fusion table.
When I do that and then view the corresponding map in Fusion the map points are offset. offset - meaning located on the map 100s of metres from where they should be.
I understand a little about the offset issue in China. However, if the OSM correctly identifies my position on the China map (I'm in Shanghai) why does the Lat and Long position not translate to the correct location when I then add that data to a Fusion table?
Can anyone simply describe the issue with GPS offset issues in China? For example my Android Nexus 5 GPS module must be providing the correct Lat and Long details is that correct? Then when they are added to another mapping service - such as Google they are offset, why? The Google Map app on my Android device correctly positions me on the map.
It's a headache, I'd love if someone can help me understand the issues and also let me know how I can correctly gather Lat and Long data on my mobile device that can be used in another mapping application - I want to create localised maps in Shanghai as part of a university initiative.
Thanks!
