Mapping considered Malicious (if Fire Hydrants) about 1 month ago

What I’m reading between the lines of their response is that some areas aren’t covered by hydrants and would therefore make good arson targets.

More Mysterious Markers about 2 months ago

Nottingham (City|Corporation) Water Works? S could be sewage or safety, V could be valve or valley maybe?

A lot of the institutional knowledge and archives would probably have become lost in the privatisation, but it could always be worth asking.

100€ for a subscription to diary comments about 2 months ago

Donated! Congratulations @mikelmaron and thank you very much! It's very noble of you to ask for the reward to be donated.

Now if we could get @mentions working... :)

The Smallest Street in Porchester Gardens, Nottingham 2 months ago

I have nothing constructive to add, but wanted to tell you that I enjoy your field reports. Thanks!

Using OSM to improve government data 2 months ago

Thank you for the clarification, Simon!

It sounds like we'll get the best of both worlds in this case then - everyone can get the best available map, and OSM gets validation and resolution of differences between official and OSM data for free.

Using OSM to improve government data 2 months ago

I'm certain that you can't launder ODbL data to become public domain data. If there were a way, it would certainly go against the spirit of OSM. The point of the share-alike clause, to many people, was to stop the Google and TomToms of the world from getting OSM data without sharing back.

I'm not sure how NYC understands the ODbL and gets errors reported. If the error reporting happens before the data layers are mixed, there is of course no problem. If there is a point where mappers can report mistakes in the data they have found without comparing the official data with OSM, it's great. If there is a systematic automatic diff with OSM, and all output is investigated, it's still a significant extract from the database.

There's nothing that stops a government from maintaining two databases concurrently, or from only releasing ODbL data.

That’s fantastic! Is the Wegenregister licensed under the ODbL? Does the central Flemish government know that it can only ever re-distribute it under the ODbL?

I’ll match your pledge, so it’s 200€ total now.

OSM Analytic Difference Engine Docker image 6 months ago

This looks very cool! I'll definitely try to get it running for Luxembourg.

The address part currently returns a 404, is it still being worked on, or is it a separate piece of code? We recently got open addresses a bit like Denmark, and I'd love to benefit from Denmark's existing experience.

Mapping Thorneywood Mount 7 months ago

British class politics aside, what has worked for me is carrying around flyers. Bright hi-vis jacket, loud friendly hellos, a bit of pontificating about open maps, and they'll be impatient for you to get on with it and leave within seconds :)

Logainm Data Import #1 9 months ago

Also, that analysis could be restricted by barony and CP.

Logainm Data Import #1 9 months ago

At the hack weekend, Dietmar and I played with similarity() in pg_trgrm. An interesting analysis would be, for the townlands with no match, to show the unmatched townlands on the other side with the most similar names. When's the next hackwochenende? :)

Help map some sidewalks for cities in the U.S. 9 months ago

Do any data consumers, renderers, or routing engines use the sidewalk=* tag?

Sidewalks! 9 months ago

Interesting! How are you planning to make it render just on the left side in this case?

While we're talking about pavements, do you know of any routing engines that use that tagging for pedestrian routing?

Easily map individual parking spaces using the terracer plugin in JOSM 9 months ago

You can save the second line by using the extrude mode (X), then alt-dragging the first line down.

Using custom Mapbox layers for mapping missing features in JOSM 11 months ago

Have you looked into creating JOSM colour styles? It looks like that would be a more efficient way of doing it.

Lets tone down mutually offensive and insulting statements with Harry Wood about 1 year ago

Should I explicitly say sorry to anyone who had unpleasant time with me? I don't want to belittle the issue, but I want to add slightly different perspective on this. It is very common for non-native English speakers to edit their messages 2-3 times. Or use rude words when trying to explain their environment.

Yes, you should at least try to be a pleasant person to map with. I'm not a native English speaker either, and manage to communicate with other mappers without insulting them.

Address evolution in Belgium over 1 year ago

Do you have an idea how complete this is, compared to the counts of the official datasets? For example, in the Grand-Duchy of Luxembourg, we have 18143 addresses on OSM, out of about 150k in the official, georeferenced address database that’s not yet open data.

OpenStreetMap Carto 2.34.0 over 1 year ago

I found your diary entry interesting, and tried to tag a bridge. Any idea why http://www.openstreetmap.org/way/368210603 renders below the motorway?
