[gdal-dev] vector NODATA for Z values?

[Abel Pau]

Hi,
there is any value in GDAL for VECTORS that indicates that a concrete value of a Z is not known (z nodata value)?
I couldn't find it anywhere.

In MiraMon format we use one concrete number documented in our format pdf (-1.0E+300) an in the driver it's planned to translate it to the same number. I could translate it to the one I am asking. And the same for detecting nodata Z and translate them to -1.0E+300 when reading another format.

Thanks!
