Does anyone have experience using Alteryx for mapping solutions in China? The WGS84 coordinate system doesn't line up with the GCJ-02 projection system used by some sources in China. Alteryx spatial tools support custom projection systems via WKT, so ideally that code exists somewhere.
The options I've found so far involve Baidu API calls which isn't ideal for complex polygons or at scale. I'd love to hear any insight or alternative options for this scenario.
GCJ-02 is a geodesic datum that is controlled by the Chinese government and not accurate for plotting GPS or spatial objections on top of it. From a user perspective there seems to be minor value for Alteryx to develop or license the algorithm for translating WGS84 into GCJ02 and supporting Chinese mapping projects, in addition to the risk that comes from supporting this datum.
Alteryx has no plans at this time to support GCJ-02 geodesic datum. We will review this requirement in the future as we see more demand in Chinese geo projects.
