I've seen several requests like this but I still have one pressing question...
GDAL is often suggested as the easiest way to convert GeoTIFF files into a different format. I downloaded several GeoTIFF files from the FAA website. The downloaded raster maps are compressed zip files which, when extracted, contain 3 files: a .TIF, a geospatial .tfw and .htm metadata file.
The GDAL command to convert the input.tif to a NetCDF output.nc is:
gdal_translate -of NetCDF <input filename> <output filename>
How does GDAL create a georeferenced NetCDF file from the .tif input file only when the geospatial data is in a different .tfw file?
If no georeferencing information is available in the TIFF file itself, GDAL will also check for, and use an ESRI world file with the extension .tfw, .tifw/.tiffw or .wld, as well as a MapInfo .tab file.
