During the process of generating them I noticed quite a few problems in steep areas that should not have been there. So began a long process of improving the contourlines. The problem was that the filters the map compiler runs against any lines were not suited to contourlines. With the help of others mkgmap is now improved a lot in this regard – and kinda resulting from this also normal maps have improved a lot when zoomed out (thanks to Gerd on his never ending improvements to mkgmap).
