Specifing NODATA_VALUE in BIL/HDR export

Qiao Global Mapper UserTrusted User
Hi there,

Is there a way to specify the NODATA_VALUE when exporting elevation grids in the BIL/HDR format? I found it is inconsistent in Global Mapper, sometimes using -9999 as void values and some other times using -999999. The NODATA_VALUE line is not written to the HDR file.

Thanks in advance,
