Hi Andrzej,
When you use --add-pois-to-areas mkgmap will generate a POI based on the existing data, and this POI will have the tag place=city (for the example), so for each tile we calculate different coordinates for the city POI.
Not only cites but all polygons can get duplicate POIs. Probably cities are worst, because they are easily accessible with search function.
yes, and they are typically so large that different POI are far from each other.
You can solve this particular problem by telling splitter to keep all administrative boundaries complete, but that will produce a lot more data in each tile: --boundary-tags=administrative
Looks like the easiest solution, so maybe we can allow for bigger tiles. I think you can save complete multipolygons too.
Hmm, splitter keeps most mp-relations complete, we only exclude some boundary relations. I think this thread shows why: http://gis.19327.n5.nabble.com/splitter-relations-to-be-checked-with-keep-co... So, question remains: Should we change something in one of the programs? Gerd
