Adam, You have fixed the projection, but you still have a problem with your tiles, I'm afraid. Look at the "halfway" tile, whose lower right (SE) corner is at the intersection of the equator and the prime meridian.
For zoom 1, it's 1_0_0.png, which is correct. For zoom 2, it's 2_1_1.png, which is correct. For zoom 3, it's 3_3_3.png, which is correct. For zoom 4, it's 4_7_7.png, which is correct. For zoom 5, it's 5_15_15.png, which is correct. For zoom 6, it's 6_32_32.png, which is incorrect. Notice the pattern there? It's broken at zoom level 6. Something is wrong with your tile cutter code. If it were me, I'd dig into the tile cutter at this point and find the bug. If you're up for that, great! If not, you'll have to contact the author of the code and ask for help, or hope that someone else on this forum has experience with that code and can offer some advice. I've taken it as far as I can, I'm afraid. String On Dec 19, 11:04 pm, adameepoo <[email protected]> wrote: > Thanks for taking a look.
