How to improve drawing of contours when zooming in a lot

[IndianBoy42]

I am using galileo for a real-time gps-rtk tracking application where I need to see the movement and path on the scale of meters, the whole area is less than 100m wide and in fact the gps-rtk has cm level precision. With galileo whenever i zoom that far in the contour lines are very choppy and not smooth and parts even disappear when I go to close. How can I control the resolution, lod or something to make sure the contour is always smooth and continuous. I think it is being limited by the resolution of the underlying tiles, but actually the contours and markers should be able to be drawn at the screen resolution right?

I have found the problem: lyon (which is used for tesselation of contours and polygons) uses f32, which has only around 6 significant figures, which is extremely easy to surpass when using coordinates or webmercator projections. 6 significant figures is not even 1 meter precision.
