it is zoomed out> or are you talking about the mod being all different like? there are different mods for cartographer that you can select. if that is your problem i would suggest going back to the wiki and selecting the correct mod your looking for have fun and good luck .
The green mod is not the same as the first image you linked. All official Cartography Made Easy mods have the Mystical Chaos logo somewhere on the map. Besides, the only green mod made by MC was a custom design for a guildmate that luckily never saw the light of day.
The first screenshot came from using the file "Elona - Cartography.tpf".
The second came from using "Cartographer.tpf". This was a mod made by Tiyuri for screenshot comparisons in a thread on GWOnline. You can use this mod for unfogging in game, but it doesn't have the edge markings that the Cartography Made Easy mods do, so it's not as effective for that purpose. It does work very well if you don't want to use texmod while you're playing/exploring, but want to take a screenshot when you've finished and see where you have left to explore.
Could someone tell me how to get this little piece to be explored?
Thankyou.

"It is important to note that all possible areas of exploration for each continent actually total up to more than 100%. On each continent, there is an observed small leeway (about 0.1% to 0.2%) to account for areas that became inaccessible as the character progresses through the storyline. On Tyria, this is most noticeable. All of the previous PvP arenas (such as Fort Koga) are no longer accessible, but 100% exploration is still achievable. On Cantha, Monastery Overlook and Shing Jea Arena comes to mind. For Elona, it would be the small Island of Shehkah."
Can anyone confirm this area in question is not able to be explored?
The mods were made after the pvp arenas were closed, so anything it says you can reach can be reached. No exploits, such as the Eradon Terrace glitch) were used, and this does not include the alliance controlled areas in factions.
