I'm watching My Liberation Notes; roughly where is that neighborhood located??

Sanpo City and Dangmi Station
Sanbon + Gunpo = Sanpo City
Dangjeong Station + Daeyami Station = Dangmi Station
It seems to be presented like this, but
it's near Suwon,
it's possible to commute to Seoul by subway,
you take a village bus from the subway station,
and there are rice fields spread out around...
Roughly which neighborhood would this be?
Are there really that many rice fields in the Sanbon/Gunpo area?
Would it be somewhere between Suwon and Cheonan?
