Here an example:
The World world * 750000N1650000W, 64, 34 750000S1650000E, 1470, 876 *
The first line is the title of this map. It is the same as in the map.db file.
The second line is the name of the image file. If the image file is a XPM file (extension .xpm or .xpm.gz) do only give the name, not the extension! If the file is a USGS DRG topo map, or another TIFF file, give the full name inclusive extension.
The third line is empty, or contains the string "DRG" if the file is a USGS DRG topo map or in TIFF format.
The fourth and fifth line contain lat/lon coordinates for the image coordinate x/y. Since you do not have to enter these values by hand, just enter all digits as 0. For geo referenced TIFF files these values are ignored.
The sixth line is empty, or contains a "*".
