Canthan Cartog Help

I've recently finished Canthan Vanquisher and im getting closer to Cartog, only need 1.1%. The biggest part of the map I have left to uncover has been giving me a lot of trouble, Ive tried it from different areas with no luck. Could anyone help?

If this helps, I had the same part uncovered and still got my title. I did some portal jumping though.(http://guildwars.wikia.com/wiki/Portal_Jumping_Project)
Now it is a good time to explore the canthan tutorial area too.

I think what you are missing there can be explored by doing the Vizunah Square mission and scrab the wall before going in the library and then before engaging the Shiro'ken at the end. If you have not yet done the mission starting from the Foreign outpost, try it. At least it helped me uncover those parts of the map.

Vizunah Square Mission.

Above post is correct

thank you guys for the help, i did the foreign quarter mission and got alot of that area, that took me down to 1% so i did some portal jumping and now im down to .3%
