Hi Enrico, mkgmap does not store the meta info and spltter doesn't write it, so there is no way to do this. Maybe you can use osmfilter for that? cioa, Gerd ---- Enrico Rossini schrieb ---- Hi, there is a way to extract in the files style the name of the mapper (user) of an element (simply a node)? for example: natural=tree mapped by user demon_box how can I extract the value demon_box in the style files? There is a mkgmap function to do this? Thanks very much. demon_box --enrico [https://mailfoogae.appspot.com/t?sender=aZS5yb3NzaW5pNzMwNUBnbWFpbC5jb20%3D&type=zerocontent&guid=0a10175b-d1bc-432a-ba86-f6df058bc159]ᐧ
