Hi, I'm trying to produce a map with more "tourism" data on it. One thing I'd like to add is castles. I managed to do this, though as many of them are areas and I wanted them as POI, I had to add --add-pois-to-areas. But I'd like to try to guess what castles are "interesting" ones, to display them on larger zoom levels. The idea I had was that the more interesting castles would probably have a wikipedia page attached to them (I live in an area where there are a lot of castles :) ), and wanted to use this as a filter, to try something like that: tourism=castle & wikipedia=* {name '${name} - ${wikipedia}'} [0x5202 resolution 20] tourism=castle & wikipedia!=* {name '${name}' | 'Castle'} [0x5202 resolution 24] (I created my own POI icon for 0x5202). But the wikipedia tag doesn't seem to be available. Is there a way to ask mkgmap to keep a supplementary tag ? Or is there something smarter I could do ? :) Regards Marc
