Re-tagging quadrant routes in Pennsylvania, USA from `ref` -> `ref:penndot`

Posted by oini on 19 January 2016 in English (English)

Quadrant routes in Pennsylvania have 4-digit route numbers prefixed with SR. OSM recommends that these route numbers be tagged with the ref:penndot key rather than the ref key in the following manner: ref:penndot=SR 6000.

  • Total incorrectly tagged ways in Pennsylvania: 6819. Of these:
    • Routes tagged as ref=SR **** or ref=SR****: 6775
    • Routes tagged as ref=Sr **** or ref=Sr****: 44

  • Incorrectly tagged ways in Pennsylvania excluding routes with no space: 3132. Of these:
    • Routes tagged as ref=SR ****: 3123
    • Routes tagged as ref=Sr ****: 9

I'm looking into re-tagging these incorrectly tagged ways into ref:penndot=SR **** to prevent any problems with mappers and data users getting confused by the mention of a reference highway that isn't normally meant for the public being in the ref tag.

The work-flow I'll be following is listed below:

  • Load overpass turbo link and run the query
  • Export the results into JOSM
  • In JOSM, find objects with the filter ref:sr
  • Rename key for selected objects from ref to ref:penndot
  • The changeset comment i'll be using is Changing key of quadrant routes in PA which are not signposted from ref to ref:penndot as per OSM Wiki guidelines https://github.com/mapbox/mapping/issues/149

For further details on the progress please refer to this repository.

This looks great! Will definitely improve the maps in PA.

As someone who lives in and maps the Pittsburgh area, I agree with this proposed mechanical edit. Strangely, there are very few of these mistagged refs around where I live; most of them are in central and eastern PA.

GeoKitten, that's because whenever I saw them over here in the Pittsburgh area, I fixed them. ;)

Also, there might be a few 'quadrant' routes hidden in the regular ref tags with another 'normal' route. Is there an easy way to find these as well and fix them too?

For example, if a ref is 'ref=US 22 Business;SR3006', would you be able to find that hidden 'SR3006' and move it to the 'ref:penndot=' tag?

Plus I hope you will fix any 'ref:penndot=Sr *' tags to 'ref:penndot=SR *' that were done in the 'test' period. ;)
