[gdal-dev] Call for discussion on RFC99: Geometry coordinate precision

[Even Rouault]

Hi,

I've drafted https://github.com/OSGeo/gdal/pull/9300 (rendered text at 
https://github.com/rouault/gdal/blob/rfc99_text/doc/source/development/rfc/rfc99_geometry_coordinate_precision.rst)

Summary:

This RFC aims at introducing optional metadata to specify the coordinate 
precision of geometries, to be able to round appropriately coordinates 
and limit the number of decimals when exporting to text-based formats or 
nullify least-significant bits for binary formats. That metadata will be 
stored into and read from formats that can support it.

Note that this is not backed by an implementation yet (except a 
prototype done one year or so for the nullification of least-significant 
bits in WKB), so there might be changes/additions to the exposed plan, 
but the document exposes the general directions
