Hi Guys, Im finally getting somewhere with the help of Chris Adams (Thanks Again) I have a map gererated, that is going to ultimatly grab image tiles from my server I now know that if my tile is 300 Px and i need a resoloution of 5,12 dd the calculation is 5.12 / 300 = 0.017066667 In my sample i am simply displaying the pink tiles for now, but it is trying to pull from my url, using the getfile function in the example so it shows get_tile.php?z=1&x=21&y=28 where z = zoom x = tile number in the x position y = tile number in the y position No by knowing the zoom level tile number etc, how could i calculate the center lat/lng of the tile needed? I thought it would be simple but how will i figure out if the lat/lng are negitive values Please help me once again K-
