Hi Hendy:
You need to have projection coordinates x and y. see:

Hi Everyone,
I am using gdal_translate to generate a netcdf from a USGS LANDSAT geotiff
data, but I'm not seeing why the grid
described below is not recognized as a grid by NetCDF Tools (4.2). Could
someone please point out the problem?
Thanks,
Hendy
