I have an ESRI ASCII file with usual 6 rows of headers followed by elevation values in metres. The NO_DATA value in the header is set to -9999.
I am trying to convert this ASCII to XYZ using
gdal_translate and do not want to include nodata values of -9999 in the output XYZ File. I am using the a_nodata command to ignore
-a_nodata values in the output XYZ file however have so far been unsuccessful in getting this to work. I'm hoping someone can help me out as to where I am going wrong with the
-a_nodata command. I've included my current code below which creates the XYZ file but does not ignore no data values.
