Could we address this by basing the predefined tiles on low-detail maps or on the mkgmap default style? If you include more detail, you could ask splitter to split the predefined tiles further. Or would that result in too small tiles? (For what it is worth, three tiles are enough for entire Finland when using the default mkgmap style. Many tracks and cycleways are still missing, as are most buildings. So, this may change at some point.) Marko
