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

[Even Rouault]

Hi,

https://github.com/OSGeo/gdal/pull/9300 has been updated with the actual 
changes from the candidate implementation now available in 
https://github.com/OSGeo/gdal/pull/9378

If there are no further remarks on the RFC in the following days, I will 
submit it for adoption.

> 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
