Copying from Google Maps 19 days ago

@Rovastar I have very occasionally heard of that happening but even then the best that can be expected of the G-word apart from Haiti is that the contributor is confused about recording provenance and has to be asked to confirm that the mapping comes from a clean source, possibly using a changdset comment.

Of course it is often a good idea to contact the mapper anyway to set them on the right route.

Maps Update: April 17 → May 13 about 1 month ago

Kivu is an ongoing project with Missing Maps. The disappearance of castles in London is a followup to https://www.mail-archive.com/talk-gb@openstreetmap.org/msg15845.html

London OpenStreetMap Q&A 4 months ago

Is the Q&A an example of the sort of event we could organise round the OSM UK meeting in Manchester this May?

State of the map Asia - 2017 and talk on multilingual maps of the world! 9 months ago

Could you explain the reasons for using Wikidata and not a solution inside OSM?

Baños Ecuador about 1 year ago

To delete a street from the map that doesn’t exist you can log in to OSM on a desktop and select the Edit tab on the top. If there is nothing at all there you can select the wrong road, right-click and and choose delete (bin). If there’s a road or path you can’t use you can select the road and change the mapping or the access. If you select too much you can divide the road with the split way (scissors) command.

Maps.Me loses OSM editing? about 1 year ago

My local area is several months out of date even if I download manually. What should I be doing?

About landuses and landcover, in particular landuse=residential about 1 year ago

Would you go as far as creating a separate landuse polygon for each block?

Long Names of OpenStreetMap almost 2 years ago

There is a mailing list discussion about using the name tag for descritions of route relations.

Long Names of OpenStreetMap almost 2 years ago

Is there ever a good reason to have multiple spaces, or is that something we should disallow?

House Numbers & Street Names almost 2 years ago

There are all sorts of weirdness in road numbering. Just today I encountered a road where the odd numbers go from south to north but the even numbers on the other side go from north to south.

OpenStreetMap past(s), OpenStreetMap future(s) about 2 years ago

The high number of node modifications in 2009 would have been the script to remove tags from imported nodes, https://wiki.openstreetmap.org/wiki/TIGER_fixup/node_tags

marriage place about 2 years ago

Is https://wiki.openstreetmap.org/wiki/Tag:government%3Dregister_office what you are looking for?

Units in OpenStreetMap over 2 years ago

Let me tell you a little story.

My day job is a computer programmer writing finite element analysis software. One upon a time we stored everything in user-specified units; sometimes they were just expected to be consistent, more often the calculations added scaling factors as needed. Originally these were just powers of ten (mm, kN and so on) but a wider variety of units went in later specifically for US use. As the number of units that could be presented to users increased it became more difficult to validate the calculations; although not so many people used some units, calculating the wrong answer is undesirable in our work.

Eventually there was a big rewrite that meant all of the calculations would have to be debugged again and, just before I joined, the calculation expert got the whole team behind him saying that in the future all internal storage and calculations would be done in SI units and existing data sets would be converted. Our biggest problem with that since then was an American dataset that claimed to have metric measurements but got the conversion factor wrong.

Improving the OSM Map - why don't we? [11] over 2 years ago

One point: although the wiki page is available in eight languages, Chinese isn’t one of them. Any volunteers to fix that?

New road style for the Default map style - the first version almost 3 years ago

An alternative thought: maybe we’re just trying to squeeze too much into one map and we should have separate styles for roads and land use.

Oxford routes. about 3 years ago

The mailing list it was discussed on previously was a small and low-volume list. It may well have few enough subscribers to risk being an echo chamber. I notice that the English-language Wikipedia lists “Please clear this with WikiProject X first” as an example of the uncollaborative editing that community frowns on.

Reading through mailing list discussions I notice that some of the participants were talking about asking the county council to declassify the road. If the removal of the number is indeed co-opting OSM as part of such a campaign it would set an unwise precedent.

While OSM in many countries has decided that road numbers are perverse as a proxy for importance, we still need to make sure that the highway tag isn’t part of a declassification campaign either.

Police Scotland about 3 years ago

Is the police website suitable for featured images?

Tram lines on Riga map almost 4 years ago

There is currently a rendering bug in the standard layer.

You can still view the tram lines on Mapquest or Öpnvkarte.
