@scruss Thank you for pointing this out. This was a manual accident I made. I am still learning how to use JOSM efficiently, and sometimes my attempts at pressing shortcuts don’t do what I expect. Rather than delete the buildings I made, I accidentally deleted everyone else’s! I have endeavoured to fix the mistake I made.

@DoubleA. I’m not away of any ongoing discussion on this. The Wiki page had no mention until I made a small edit about it. I would very much like to know of any locations of discussion about this.

@scruss. A very good point. I wanted to expand in more detail about how I made the changesets in my next post, but would appreciate some feedback on it here beforehand if possible. I thought the way it was used was not an import, as I considered each footprint individually. In a similar way to having a map layer like cadastral parcels as an overlay, it was used as a tool to aid in mapping houses, rather than simply copy-pasting large data across. Would this be considered an import due to use of external data?

@SimonPoole. The database license is ODbL, which is the same as OSM, and hence should not have issues between them. Is there some further license issue?

This is a very good and clear tutorial. In the couple of months since I’ve started I’ve picked up most of these processes, but still learnt some new tricks from this. I would really like to see something like this advertised to new mappers, as this post really helps provide a process for “what to do”.

Really like this. Great guide, and nice to discover a neat way of browsing OSM through OpenStreetBrowser
