Mark’s Known World and Sea of Dread, 24 miles per hex v2
Three years after posting his Worldographer map of the Known World at 24 miles per hex, Mark posted a new Paint.NET version, this time finished to a high level of completion. It included not only labels, but also revised terrain and sea depths to match his new Known World, 8 mile per hex trail map. He explained in his post at his blog:
The next stage of my mapping process is to create 24 mile per hex versions, but using a “look through” to the underlying 8 mile per hex maps. This is done by taking the water layers, scaling them down, and then taking the underlying terrain from the 8 mile per hex maps and approximating what would be the best fit for the terrain at a more zoomed out scale.
This is therefore not just a reprisal of X1, but an update, taking into account the new terrain details on the larger scale 8 mile per hex maps, reflecting these back into the regional map. I have long planned to do this myself, but have never found the motivation to bring such a map to completion. Bravo, Mark!
He also provided a version with the hex grid turned off.
