Below is a link to a high-definition map of The Coast. Readers may find it illuminating.
Here's a Google Drive link to it. Bonus red-lettered version here.
This version is 40% the original's substantial 8K resolution. I've made the original 8K version available historically, and will re-release it at some point for a small supporters' fee in the future.
It's a project of several hundred hours, divided mostly between Autodesk Sketchbook and Photoshop. The lettering alone is composed of over 1,300 words.
I'll update it occasionally, as required. Current version stands at 1.0.
