The image shows a tree rooted on a disk. Surrounding the trunk and extending up into the branches is a large globe.  Extending out from the disk are seven rivers.   On the banks of one is a small building representing Midgard.
 From this a rainbow of color curves upward to the middle of the globe ending at the central trunk of Yggdrasil, representing Asgard.  Below Asgard, a mountain range resks on a disk of earth surrounded by a larger disk that extends to the sides of the globe.  This larger disk is ringed with icebergs.  Extending on the sides of the this larger disk are the other two branches of Yggdrasil, which curve up the sides of the globe, which represents the sky.

This image represents the cosmos of the Norse world and Yggdrasil, the world-tree that stands at its center and supports the cosmos.
