[gdal-dev] OGR support for POINT ZM

[Gottfried Mandlburger]

Dear GDAL/OGR team,

I just realized that there is no support for the OGC "POINT ZM" geometry 
in GDAL/OGR. It is well possible to read in a 3D point with an 
additional attribute from the following OGC compliant WKT string...

POINT ZM(1. 2. 3. 4.)

... but the attribute value (i.e. 4.) is silently ignored and not 
reflected in the OGRPoint data structure. Especially exporting the above 
contents back to WKT, results in...

POINT(1. 2. 3.)

Any plans to add POINT ZM support in GDAL in the near future?

Kind regards,
Gottfried
