What source did you use for the La Honda Expressway and Willow Freeway? These were planned but never built. Can you please delete them or use highway=proposed with an appropriate end_date?

Hey, this is fantastic coverage of the Las Vegas area so far! Would you mind adding citing the specific aerial map in a source=* tag on the features you mapped from it? Citing sources will be important especially as we sometimes need to reconcile conflicting sources. For more information:

Thanks!

Many of these ways have gone through a series of atypical, undocumented tagging schemes. Would you mind writing up what you envision for these tagging schemes on the forum or a draft wiki page, so we can determine whether it makes sense for software and mappers to adopt them? Thanks!

The following changesets fix gaps in boundaries caused by this changeset:

https://www.openhistoricalmap.org/changeset/151868
https://www.openhistoricalmap.org/changeset/151869
https://www.openhistoricalmap.org/changeset/151870
https://www.openhistoricalmap.org/changeset/151871

If you edit a sparse download, remember to also download boundary=timezone and other boundary=*, not just boundary=administrative. Alternatively, before splitting any way at a node, select the node and go to File ‣ Download parent ways/relations.

Thanks for your attention!

I missed deleting the San Diego County place point; fixed in changeset 149969.

Thanks for noticing and fixing the coastline here! For now, the renderer only knows how to deal with a single fixed coastline rather than one that changes over time. It’s an unfortunate limitation. The workaround would be to map the modern coastline and represent the extension as a body of water that went away during the eruption. Feel free to post here or in the forum if you need any clarification on that.

Hi, it looks like you replaced some streets with bare ways that are part of multilinestring relations. These edits came up in an ongoing discussion on the forum about how to model a road that has changed over time; please have a look. Thanks!

It looks like you deleted some POIs and streets that another mapper had traced from a Sanborn. Is that because the Sanborn was incorrect? If the feature is correct but can’t be dated yet, set the start_date=1924 start_date:edtf=/1924, which says it existed by 1924 but may have existed earlier than that.

Hi, I noticed you deleted several streets in Sulphur Springs. These streets seem to still exist, so they should be mapped somehow. If the problem is only start_date=1931 based on a 1931 map, then instead of deleting the street, add start_date:edtf=/1931 to indicate that it could’ve existed before that year. You could also contact the original mapper, MrMap, to see if they’re able to find a more precise source about when the town was platted.

Hi, a series of these changesets (including 142484, 142526, and 142518, among others) split ways without copying over relation memberships, resulting in gaps in boundary relations. I fixed this for the time zone boundaries in changesets 142532, 142533, 142534, 142535, and 142537, but ways like 200574927 continue to be gaps in various subnational administrative boundary relations. Could you please fix these gaps and double-check that your JOSM workflow downloads any coincident boundaries before splitting ways? Thanks!

Hi, each of the members of relation 2831059 needs an “inner” or “outer” role. You should be able to detect this problem and others like it by running the JOSM validator. Thanks!

Not sure how this happened, but the end_date on one of these relations caused a nasty bug in iD: https://github.com/OpenHistoricalMap/issues/issues/826

By the way, in case in helps, Caltrans maintains a comprehensive dataset of state- and locally-maintained bridges in the public domain. Feel free to crib from it: https://github.com/codeforsanjose/OSM-SouthBay/issues/24

Interestingly, OSM seems to think the counties don’t include water even today. By the way, you might be interested in this broader discussion:
