I’m sure this must have been asked a zillion times on here but I don’t seem to be able to find the answer
I have successfully used the formula to calculate a png tile from a lat/long
How do I now calculate the eight tiles around that and then the sixteen around those
Thanks in advance

Thanks for the reply
I’m not sure how that helps me … unless I am missing the bleedin’ obvious ?
The tiles are numbered sequentially starting from 0 at the west and north according to this. It should be as easy as incrementing and decrementing the x and y by 1 to find the adjacent tiles. For the 16 tiles, you’d increment and decrement by 2.
