welcome! it's going to be a challenge converting those flat maps to a spherical and/or equirectangular world map, though very interesting!
My name is Q, aka Jeremy, I been supporting a gaming world for almost 20 years (this October). I have hand drawn maps, bitmaps, jpegs and now my newest gift from loving gamers and an amazing wife is the entire cc3 software suite. Only one request was to put my world to an interactive mapping system, for quick reference purposes. I sat down did the math and found a daunting project ahead of me, my Maps with they're scales seem to meet, if not succeed Jupiter's Surface area. LoL. So I begin, and joined to have aid in ideas and sounding boards, for this task. I figured with others loving the Cartography it might not seem as large as it is and this gives me a place to share what I create with out giving to many spoilers to my gamers.
I've tried in my times to keep the maps and mass placements to certain Laws.
and thank you
Welcome to the Guild Quorpeck! Looking forward to watching your project take shape.
