Nordfjordeid - Norway in 3D

This is a 3d model by a site called http://terrafab.bengler.no/ where you choose a part of norway and they generate a model with the mesurements from http://www.norgeskart.no/?_ga=1.23422522.1200005049.1454086583#5/61341/6970185

I made the model i 150% so it became 15*15cm and in height i used 155% since then i got land to become one layer hight higher than the see, but this only works with layer hight 0,15.
