[mkgmap-dev] Too many pois on multipolygon areas

Tue Sep 27 11:23:04 BST 2011

I have enabled the add-pois-to-areas option, because this way I can search for a certain tag that is placed on an area like landuse=*, tourism=* or building=yes. But sometimes those pois are cluttering the map, especially if this area is a type=multipoygon relation. 

Take for example this multipolygon relation: http://www.openstreetmap.org/browse/relation/949481
tourism=zoo is tagged only once on the outer way: http://www.openstreetmap.org/browse/way/61046378

However, the multipolygon function of mkgmap splits this area up in several parts (to render the inner islands, which is fine) but it also creates too many pois by the add-pois-to-areas for this one tourism=zoo area: http://img546.imageshack.us/img546/5763/zoow.jpg

I'd like to see just one elephant icon instead of several. Is it possible to execute the add-pois-to-areas action before the multipolygon action takes place?
Or is it possible to set some rules in the style file to make some exceptions for areas with type=multipolygon?
