Addon was written due to survey inaccuracy :
Store dig sites, store coordinates (data gathering with help from my guildmates and you will help populate) and try to guess the location, keeping track of new nodes you might encounter.
Now holds 101 dig site and 508 nodes (Eastern Kingdom and Outland only)

How to use ?
-Travel to a dig site
-Cast Survey
-Look in given direction
-Click on the button with same color as survey gave
-Addon gives you either stored coordinates that match, either try to guess

When recolting fragments, if coordinates are unknown, it will store it.

If you want to help me gather nodes coordinates, you can send your local storage file to ArcheoTriangle@gmail.com
(you can find it in your world of warcraft folder, under \WTF\Account\YOUR_ACCOUNT_NAME\SavedVariables\ArcheoTriangle.lua)
Thanks ;)

And I would like to thanks all the players that sent me some info to help me populate the dig and node list, it's great !
