Hi Nick, thanks for reporting. I can reproduce the results and I think I found a fix, see attached patch. The content of the if-stack was corrupted. @Steve: Please review, maybe there are other places where copy() should be used?

I insert the following in polygons (default style) at the end ,just before <finalize>: if (area=yes & landuse!=residential) then landuse=* {set name= '$(landuse)';} (landuse=*|waterway=*|amenity=*|natural=*|leisure=*) {echotags "mopping up area"} [0x10910 resolution 24 continue] end I use the Ireland & Northern Ireland pbf from Geofabrik The echotags list includes some puzzling entries 1) some entries (see below) do not include 'area=yes', ie landuse=religious & landuse=plant_nursery 2) it also includes landuse=residential despite having specified 'landuse!=residential' in my 'if statement' Regards Nick This is part of my echotags list File:d:\temp\ireland-and-northern-ireland-latest.osm.pbf * mopping up area * Way 194526400 landuse=religious mkgmap:cache_area_size=242.848 ------------------------------------ * mopping up area * Way 456431379 area=yes landuse=flowerbed mkgmap:cache_area_size=35.741 mkgmap:if:1=true name=flowerbed ------------------------------------ * mopping up area * Way 452524709 landuse=plant_nursery mkgmap:cache_area_size=4250.272 ------------------------------------ * mopping up area * Way 465641413 landuse=religious mkgmap:cache_area_size=614.697 mkgmap:residential=yes ------------------------------------ * mopping up area * Way generated from 456431378 area=yes landuse=flowerbed mkgmap:cache_area_size=64.662 mkgmap:if:1=true mkgmap:mp_created=true mkgmap:stylefilter=polygon name=flowerbed * mopping up area * Way 465641413 landuse=religious mkgmap:cache_area_size=614.697 mkgmap:residential=yes -- Sent from: http://gis.19327.n8.nabble.com/Mkgmap-Development-f5324443.html _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
