LOTR Maps

I reacently bought The Silmarilon, I have not read the book yet for I am short on time. It had a map in it, as most JRRT books do, I was wondering if this map is of the same general area as the maps in LOTR area. None of the names were the same, but the coastline looked somewhat similar. This is a burdening question...... j/k, but I am really wondering.
Thanks
