I need to convert a
.tif file into a
.map format. How can I do it? Is it possible using GDAL?
As per this list the 'OziExplorer .MAP'-format is not supported for writing in GDAL.
If that is not actually the format that you are after, you can probably find the one you actually are looking for on the same list.
You can do it easily in QGIS in raster> Conversion >translate (Convert Format)
