I found some odd data in the tags on some sampled ways, including ways with the same id, tstamp, version with slightly different tag data (like space insertion or char(127) insertion) between the 2021 and 2022 data. One example is way 129970575 with a tstamp "2021-07-28 18:10:02" version 9. My older data from 12/2021 includes tags: "{HFCS,""Minor Arterial"",name,""Walton Way"",lanes,3,oneway,yes,highway,primary,tiger:cfcc,A21,tiger:county,""Richmond, GA"",tiger:reviewed,no,tiger:zip_left,30901,tiger:name_base,Walton,tiger:name_type,Way,tiger:zip_right,30901}" But the newer data from 3/2022: "{HFCS,""Minor Arterial"",name,""Walton Way"",lanes,3,oneway,yes,highway,primary,tiger:cfcc,A21,tiger:county,""Richmond, GA"",tiger:reviewed,no,tiger:zip_left,30901,tiger:name_base,Walton,tiger:name_type,Way,tiger:zip_right,30901}" |

I might be wrong, but there are definitely a couple of extra characters in front of A21 that don't copy/paste as spaces if you view the way history https://www.openstreetmap.org/way/129970575/history and as you post above the most recent edit was July 2021, so however you got the data in December must have removed them, and no longer does. Looking back in the history, the non-printing characters were added in version 8 in 2015. Like you said, if these weren't present in gcapilot's December 2021 data, that must have been a result of the tool-chain used to retrieve the data. The "correct" state of the data should include these characters (though they obviously shouldn't be in the database at all).

Thanks very much! I need to learn how to view history in that way. I used osmosis in both cases and it is entirely possible that those [DEL] characters got scrubbed somewhere along the line! It looks like there were several instances of the chr(127) being inserted in various places in the current OSM ways that I'm using - the following list of way-id and versions all have this chr(127) character embeded : 382363986 4 15025131 14 20143848 6 129970575 9 14664038 11 52109740 6 356378230 7 374035295 11 420904921 5 611000788 3 562474719 2 699814543 2 883155980 2 858385263 2 776387551 2 883155981 1 894524157 2 12289973 4 11466281 7 11466289 7 5584156 9 |
