[gdal-dev] RFC 61: Call for vote on adoption

[Ari Jolma]

One more issue came up.

Shapefiles, which have Z will also have M, at least a placeholder for it.

Having shapefiles as XYZM always in that case may be problematic.

It is possible to use the open options SHPT=type to override the 
default. We could have Z => XYZ as default for backwards compatibility 
and require open option for Z  => XYZM.
