[mkgmap-dev] Small holes in boundary coverage

Hi, I have compiled world bounds using the performance branch. They can be downloaded from http://www.navmaps.eu/wanmil/bounds_perf_20120313.zip. I have checked the coverage of different admin_levels with the BoundaryCoverageUtil. The result for admin_level=2 can be downloaded from http://files.mkgmap.org.uk/detail/61. Some countries are missing (USA, Canada, some african countries). I assume that their boundaries were/are corrupt. The more interesting thing is that there are small holes throughout the world in admin_level=2. They seem to be created by the bounds preparation and should not be there. Gerd, can you please have a look on it? Thanks! WanMil
