=C2=A0 =C2=A0 =C2=A0 =C2=A0 with the command line indicated above, lon lat =

Alternatively, the cs2cs command can receive as an extra argument the<br>
name of a file containing the coordinates, I suggest you to experiment<br>
with all the variations. Notice that the order of the coordinate is lon<br>
lat, not lat lon, but there are switches to change this as well as other<br=

formal aspects of cs2cs behavior, please refer to the cs2cs/proj<br>
