Misaligned Tiles #77
Comments

Well, I’m guessing there’s something going wrong with calculating the lowest overall elevation. From memory, I think I grit the elevation min() of all tiles and use that the bottom for all tiles. Does this all happen for say just 2 x 2 tiles?

Any idea what could be causing this? Thanks for your help!

yeah, it seems like the less tiles i have, the less the severe the misalignment is (which would make sense if its related to the lowest elevation computations) |

OK, I”m guessing I broke something then recently in that area when I added the min_elev setting. If I get some time tomorrow I’ll have a look.

Luke, I messed something up during the min_height parameter implementation (as I had suspected) and it should be fixed now. Thanks for telling me! |
