Ok.

i have a idea, i know that my geological map shows up in game by pressing "m" then by pressing "l".. i think , you know that greyed colour map you get when you inside a dungeon etc? thats fine..

but what i want to know is with my big world mod im doing now.. can i get the actual map that shows up the skyrim world when you press "M" *In game (the one with all the little map markers etc).. EXEPT, have MY MOD MAP show in this fine detail instead of the base skyrim one?? if so how do i go about that? surely i cant be the only one who wants this!

If you generate complete LOD for your custom worldspace, then the map will be of your land. I just made a tutorial on doing just that: http://www.youtube.com/watch?v=kB2rqH7Ytko&feature=youtu.be

Have you generated landscape LOD and created a .lod file for your worldspace?

EDIT: Ninja'd.

Firstly, you have to generate LOD for your world. Follow the tutorial - http://www.youtube.com/watch?v=kB2rqH7Ytko&feature=youtu.be by Alexander J. Velicky

If you already have your LOD, go into the CK and under World > World Spaces, click your worldspace. The Second box down (Parent Worldspace) has to be set to NONE (top of the drop down list). Save.

That's it

thanks guys!

but i downloaded and watched the start of the tut video, now i have the Nexus mod Manager. but i cant for the life of me find how to open the BSA BROWSER!
i double click on the skyrim "meshes" in skyrim/Data then the nexus mod manager wants to go to the main window for PLUGINS & MODS with tools and setting at the top of that.. how do i make the meshes file open up the BSA BROWSER so i can do what the tut says? thanks alot

You can also use http://skyrim.nexusmods.com/mods/247/ to extract files from BSA files.
