This is an alternate build of 31203 – World Map which means you don’t need any extra part and you can build this Map of Korea!

Legend of the map:
Tan: Sea (shallow)
Medium Azure: Sea
Dark Turquoise: Sea (deep)
Dark Blue: Sea (very deep)
Lime: Plain
Bright Green: Slope / hill / trees
Bright Light Orange: Hill (tall)
Orange: Mountain (very tall)
Coral: Major urban area

Why there are seagulls?  Because the blue part is not enough, therefore I have to use more white parts.  If you have blue parts in hand (or going to buy some), you may remove the seagulls and also replace the Tan with say Light Blue so that it looks more sea-like.

The size of this map is as same as the official set.  You may refer to the official building instructions for the frame.

Hope you will like it.  Thank you.
