The mp is tagged wrong. http://wiki.openstreetmap.org/wiki/Multipolygon#Tagging points out that the tags are taken from the relation if it has at least one tag beside type=multipolygon. mkgmap follows this rule strictly since r1711. The relation is tagged with name=Manila City Hall so the resulting polygons of the multipolygon are tagged only with name=Manila City Hall. Please follow the single and easy rule: Put all tags of the multipolygon to the relation and not to the outer ways. The bug that multiple POIs are created multipolygons could be easily fixed. I wasn't aware of this problem. I will post a patch within the next days. Have fun! WanMil
This way is tagged as a amenity=townhall and a multipolygon relation: http://www.openstreetmap.org/browse/way/24159829 http://www.openstreetmap.org/browse/relation/452620
In my style: polygons: building=* | man_made=* | amenity=* | tourism=* [0x13 resolution 24]
and in the points: amenity=townhall [0x3003 resolution 21] building=* [0x6402 resolution 24]
I have the add-pois-areas switch enabled
This resulted to two POI icons (the little PH flag) in garmin http://farm2.static.flickr.com/1290/5184379090_bbeeeaffc8_b.jpg
