The first time I did a marriage extension at the Sakon Nakhon office I presented a perfectly prepared google map, giving clear directions to our village home. No, not acceptable, it had to be hand drawn. My wife volunteered her services and draw what was deemed to be an acceptable map.
Using this 'acceptable map' it took the visiting IO over 2 hours to find our gaff, which, whilst rural, is only a 20 minute drive from the city centre. I've presented a computer drawn map ever since then, which has been accepted, however no one's been to visit us anyway.
I wonder if they'll ever learn how to use google maps on their smart phones. All they would then need be the coordinates.
