A grave location is a place where there are graves. It is a graveyard, or cemetery.
This word uses the kun'yomi for both kanji, which is fairly unusual, but then graveyards are unusual and special places. You've learned both of these readings before, so you should be able to read this on your own, but here's a reminder for 墓 just in case:
When you're finally dead and buried in a graveyard, your one wish is for the New Zealand All Blacks to do the Haka (はか) over your grave. If you don't know what the haka is, look it up, it's pretty neat.
If you live next to a cemetery, ghosts might knock on your door.
