Of course. I am pretty sure it matches the license, but will double check with the source to make sure. I did not copy the map 1:1, just used it for reference in order to make sense of the sat images.

thanks for the tip... will look into it. The "names" of the buildings (the numbering) are based on a detailed map of the entire factory area. I suppose it is based on the real estate registry. The map also contained all the buildings as well as the railroads (now dysfunctional). I synced the map with satellite images and I have been to the area a couple of times. Regarding the categories of roads I categorized trails as highway=path. The "main roads" (mostly concrete plates) I categorized as highway=secondary. There are also many really small kind of access roads which do not really have pavement but are wider than a trail. More like a forrest road. I categorized those as highway=service. To be honest I am still struggling how to tag the roads since most of the tags in the wiki do not quite fit reality.

I did not want to offend anyone! The names where used in OSM based offline maps for a scenario game and where not supposed to be published to OSM. I reverted the names right away.

I am sorry must have been by mistake.
