Portolan Map Possibilities

Diane had her account deactivated but she asked if I could add this resource to the thread, The History of Cartography entirely online:

I would comment more here but I'm afraid I know too little about this subject, I should read up when I have time..

Yes, this is a wonderful resource, years ago i saved all the pdfs in case this page should disappear. The history of cartography is basically a history of the world and how people have grown to understand it. Ironically, they are all stored away on my dead laptop. But since the page still exists it is probably easier to access directly 

So thank you, and please extend my thanks to Diane as well, for the link to the entire collection. The resource I reposted of JKPs above is one of the pdfs in the collection, chapter 19 of volume 1.

I really do need to learn more too, all i know is what i remember of my readings back when i first looked into the manuscript and saw the geographical connections that i still do. i am definitely not very well versed in reverse engineering of portolans, but the possibility that it could be the case that portolan coordinates might be encoded needs to be investigated, so i will give it a go, but it will probably take awhile given my starting point is one lacking in experience in both portolan charting and vms text decryption, or even solid understanding of what is known so far re its structure, but it does appear that language translation has so far been unsuccessful, so perhaps it is names and coordinates.

Feel free, anyone, to comment with your thoughts on this process, no matter your expertise, it may help to direct my search into the possibilities.

At the moment i am searching for examples of an actual sailing handbook of the time to see how the details are laid out, but so far it is just descriptions thereof that i have found, which don't describe the part i am after. But so far the correlations with most of the amalgamated versions starting in southwest Portugal and travelling clockwise around the Mediterranean, and other main ports mentioned, i think there is a chance that part of the vms might be one of these examples, if not all of it.
