<p>I'm helping answer <a href="https://stackoverflow.com/questions/29444803/does-a-google-maps-coordinate-map-to-the-same-location-in-baidu-maps">several</a> <a href="https://stackoverflow.com/questions/15448149/googlemaps-gps-location-is-always-offset-in-china">questions</a> on StackOverflow <a href="https://gis.stackexchange.com/questions/141542/what-causes-the-gps-offset-shift-in-china">and GIS.SE</a> regarding the unique coordinate system used in China, and its interaction with Baidu Maps.</p>

<p>While trying to machine translate the <a href="http://developer.baidu.com/map/jsdemo.htm#a5_2" rel="nofollow noreferrer">Baidu Map coordinates conversion API</a>, I have these two strings:</p>

<ul>
<li>google坐标转成百度坐标 - Convert Google coordinates into Baidu coordinates</li>
<li>原始坐标转成百度坐标 - Convert ??? coordinates into Baidu coordinates</li>
</ul>

<p>I'm trying to understand what the second description refers to. The "real" GPS coordinates (WSG-84), or the "original" i.e. approved by the State Council <a href="https://en.wikipedia.org/wiki/Restrictions_on_geographic_data_in_China#Coordinate_systems" rel="nofollow noreferrer">GCJ-02 coordinates</a>?</p>

<p>Google uses WGS-84 coordinates, so I'm inclining to believe the second option, but I see no reference to GCJ-02.</p>

原始 means "original", so I guess the second process is to convert original back to baidu coordinates?

@Flaudre: right, but I wonder what exactly "original" means. GPS, or GCJ-02?
