GPS Accuracy (Double)

Input

-

-

I'm working on a GPS application and have come across a major issue which I believe is relatively easy to fix. The problem exists in the use of single precision floats to represent the latitude and longitude values (LocationInfo).

The use of single precision floats (approx 7 significant figures) instead of double precision floats (approx 16 siginificant figures) means that the maximum precision that unity can represent is approximately 8 to 11 meters in locations which only have 4 decimal places of precision.

Please update the API to use double precision floating point values.

    We should be able to get the data with double without having to use a plugin!

    AR definitely needs this function!

    How has this not been addressed yet??? As AR continues to evolve, developers are going to need more accurate location information. I really feel this is hindering progress in the AR world. I've seen the workaround for iOS. Is there a similar work around for android?

    How can we escalate this issue?!

    PLEASEEEEEEEE fix this.
    AR content rely on real world coordinate precision.
    Using float as lat, long are useless.

    Please fix this, GPS data is totally useless for anything more than a demo.
