Hi all, If I got that right the dem-dist value 9936 means that splitter should create boundaries with a multiple of 621 map units: 621 * 256 = 158976 = 16 * 9936 This should work fine for 3312, 6624 as well.
It seems that we always see problems when a tile boundary is far away from this. I assume that Garmin selects all dem-dists values so that there multiples are close to certain values and those values are used to split. The overlap in TRE seems to allow small differences, but e.g. a split at lat 2424800 never works with 3312,6624 or 9936, and Minkos tiles were split at this lat. So, the current patch for splitter doesn't help as it tries to align to 1/360° when you use --align-for-dem=360. I still try to find out how many levels we have to align, maybe only the first and the 2nd are important, maybe all. I am not yet sure what that means for the split algo.

Will do some more checking tomorrow. Again, congratulations on a major achievement! Nick On 08/02/2018 20:36, Gerd Petermann wrote: > Hi Nick, > > okay, sounds good.
