Hi Jon. I've replied to your email. As I said there, I think you've misunderstood the concept of the Geomorph range, and so there's no single large map to make, but instead it's a set of 5 10x10 tiles that you can arrange as you see fit. Each page of the pdf prints one half of a 10x10 tile, with a slight overlap for alignment assistance. And for additional help, you can see full previews of each tile in the product description here, to help you piece together the sheets.
Like all the Adventures in Filbar, thIs is good and solid. A good location to build on. If I had one request/suggestion, it would be to put the map in the front, as opposed to after the descriptions.
A fun, semi-detailed city. A small City State of the Invincible Overlord without some of the goofy Judge's Guild 1970ness (and I was a player and loyal customer!).
This is one that I printed and will use.
