(Since you mentioned considering remapping these maps, can I make a suggestion? Hope it's not too scathing to criticize maps in the same topic that I am praising them... But since the series is about how you "gotta catch 'em all" (I mean, it says so right there on the box), would it be much to ask for the maps to indicate where each of the Pokémon species are found and their rarities and other pertinent information? I know there are entire web sites dedicated to Pokémon but even so I still haven't seen really good maps that show all their locations. Now that would really be something!)
I was actually tempted to do that with Pokemon Crystal as a bit of a test-run for the idea - it danced around in my head during G/S. Granted, it's not as pertinent in Gen. I & II (because the Pokemon earned there can't be transferred to the newer ones, whereas they can in Gen. III onwards), but I figured it'd be worth a shot. I probably WOULD have tried it during G/S, but localization complicated the issue. (The Japanese Silver exclusives are the international Gold exclusives, and the reverse is true as well, so the thing would've been plagued by complex tables from the start.)
Really, it shouldn't be that hard. Just give my guide on GameFAQs some HTML formatting and copy and paste a screenshot of it and it might work. ... Not that it's really ideal to reformat a whole guide, because it can be tedious, so I might just do the tables and use their preview tool for HTML guides. It might end up being a problem for larger areas like the Safari Zone, though, because of the huge number of encounters present there, varied based on the portion of the area, so it could clutter the map up. I might have to reinvent my formatting for that scenario, but I think I already have a prototype in mind.
What kind of data do you think would be relevant? Pokemon species and possibly rarity, if I can find the values, obviously, but beyond that? The thing is that I would probably get too anal on this and list type, ability, EV yield, base stats, possible hold items ... lol.
In any case, any project redos are a bit down the road. EO2U is kicking my butt at the moment; a week or so from now mark six months since I started working on it, by far the lengthiest project I've ever tried -- and I'm the guy who documented EVERY bit of data for Pokemon, learnsets, EV yields, base stats, everything for Black/White 2 -- and even then the maps themselves could use a redesign, though their reception on GameFAQs has been decent thus far. I only hit 21F last night, marking 25/35 (5/7 or about 70%) completion. >_>
