You're thinking of the import feature for Cartographer Bookmarks/Notes. I haven't used Cartographer before so I don't know if it records resource nodes. There is also an import feature for Carbonite Data also, this latter one is the one that imports resource nodes, but only from Carbonite data, if I recall correctly.

Right now, just started actually, I use Gatherer along with Carbonite. If carbonite doesn't show enough nodes for me to make good routes, I toggle on Gatherer in that area and go mining, which slowly populates any missing nodes Carbonite has.

Keep in mind, a lot of node locations in Kalimdor and Eastern Kingdom changed with Cataclysm, which is why some areas are void now of node data in Carbonite.
