WDYTYA magazine announced that the Church of England has plans to map all burial grounds within 5 years.
There are 2 churches already done and looking at it there will be grave photos, if there is a headstone, and burial register images if not. Not sure if you get the register image if you get a headstone as I've only just started looking.
This will be awesome once it is complete.
