[OSM-talk] Duplicate TIGER ways along county lines

[dasdjenne at comcast.net]

Good evening, 



  

I have been editing the map around Denver, CO, but so far have avoided fixing duplicate ways straddling county lines.   I.e., one physical way is represented by two ways, one for each county.   For a correct and visually pleasing map, ease in joining intersecting ways, etc., I think it would be better to have only a single merged way on the map corresponding to the lone physical way.    Will that agree  with OSM standards?   If it will, some tags and values may have to be modified.   Assuming merging the ways in this manner is acceptable: 



  

How necessary is it to preserve left and right county names (the county line is present and should have this information)? 

How necessary is it to preserve left and right zip codes in the way data? (These are frequently inaccurate, and I would prefer not to have to research them). 

Should the two different TLIDs be combined in the TLID tag and separated with a semi-colon? 



  

Some county lines are conveniently located along divided highways.   In these cases, I have been simply migrating each of the two ways to the correct side of the median while paying careful attention to the way’s direction and the various left and right tags. 



  

Thanks for any input. 

Dave J
