This photo is of one of the many canals in Samut Songkhram (สมุทรสงคราม - lit. Ocean war). It was taken at the house of a Thai artist who has a few bungalows that can be rented in a coconut plantation.
The panorama shot is made up of five photographs taken in August 2006 CE.
Don't get สงคราม songkhram and สงกรานต songkran confused!
