This is a completely vector-shaped fold-up map with easily customizable map section due to simple perspective transformation and layer mask technique. Just put your 2D map above the demomap layer and choose Edit > Transform > Distort (in Photoshop) to transform your map accordingly to the demomap.
The PSD file is fully grouped and layered. All effects are applied as layer-effects, so everything is easy customizable.
