I was trying to show my girlfriend her house on google earth. However google eath is limited on village names, we had trouble spelling the name of her village in english. Does anyone know where i could find a detailed map (in thai) for us to compare with google earth? then hopfully we could locate her house on google earth.

No details but with this map you can at least see where it is:

Zoom in on Yasothon and follow route 2169 NE until you see it. Are you going for Bong Fai or Songkran?

Give Google Maps a try: http://maps.google.com/

You can select "street view" or "satellite" and perhaps narrow things down. Sadly, no latitude or longitude indicated.

Note at the bottom here (http://en.wikipedia.org/wiki/Amphoe_Kut_Chum) short discussion of currency, interesting.

You could give PointAsia a try. It's pretty good quality compared to google

Here are the coordinates for the Kut Chum Hospital.

N16.02077 E104.33819

She should know where she lives from there.
