ask for help

I’m a newbie to this forum,and I’m desperately to know how to generate a table which contain the data including building,road,and we know they are all stored in different file.the only method to map the related information is mapping the coordinates.Is there anyone has any experience in mapping the data I mention?Please kindly advise.I will be much appreciated.Thanks very much.

It’s not a good idea to post the same question in many different forums. That makes it harder for other people to follow the discussion.

Is there a way to create a JOSM preset that automatically adds the node to the relation?
Member_expression looks promising, but I can’t find a good guide how to use it…
