You can't really re-scale if the aspect ratio isn't the same.

I would have first re-scaled the original map, then started a new one in the correct size, then using clipboard copy to copy over the things from the old map, dropping the stuff that is now outside the map border.

Thanks Wyvern. Map now in the atlas:

Thanks Jim. The maps are now in the atlas:

From a standard CC3+ installation, the Mike Schley Overland, Jon Roberts Overland and Herwin Wielink sets all contain mountains without shadows.

The Isle of Zariq is now in the atlas. Thanks for the contribution.
