I have a problem with the display of gmt netcdf produced with version 6.2 in format
CF1.7 (IO_NC4_CHUNK_SIZE auto, IO_NC4_DEFLATION_LEVEL 0), it's nf, netcdf 4 in global mapper v20.1.2.
The points without value (Nodata, NaN) are displayed in black whereas previously the
nodata values wasn't displayed. I tried :
-> to change the parameter of gmtCOLOR_NAN (which changed from 127.5 to 128) but that didn't change anything.
-> By trying to pick the color to make it transparent, it also removes all shading.
Any idea to solve the problem ?
