Hi Frank, just out of curiosity: Can you explain why you use an extra classification process? Does it offer more capabilites than the style system in mkgmap?

Perhaps it would be better, i change my classification process a little bit and generate for my "private" tags additional name tags (LINE_MOTORWAY -> LINE_MOTORWAY_NAME). That increase the osm files but anyway. Frank Stinner
