A missing zoo! 15 days ago

Update: Looking pretty good on the wikivoyage map now (the wikimedia maps have rerendered)

Someone is trying to steal the information of people 16 days ago

Yep stay safe online.

Just to clarify. When you say "send messages", do you mean via the OpenStreetMap 'message' feature? (Is this person an OpenStreetMap.org signed up user?) That could be something OSM sysadmins can try to tackle, at least block this user. It's worth others being aware that phishing messages could come via these OpenStreetMap channels.

If you do want to donate money to the Red Cross: https://www.redcross.org/donate/donation

If you specifically want to support humanitarian mapping, donate to the Humanitarian OpenStreetMap Team: https://hotosm.org/donate

If you want to support OpenStreetMap (e.g. to help volunteers run the core server infrastructure): http://donate.openstreetmap.org

But of course you should check these links (e.g. search for them independently) before getting your credit card out, because you don't know me. I could be phishing!

Tree named pubs of London 3 months ago

Thanks mmd. I was hoping someone would post that :-) That's good to have for future reference. I did actually start out trying to do this with Overpass, but wasn't sure how to do it exactly, and also I gave up because it was timing out. I see you've got a longer timeout set there too, so it works!

An advantage of this, is that it retrieves a proper boundary around London too. I guess that's part of what makes it take quite a long time though. My approach with osmosis just did a London bbox (although you can do polygon boundaries with osmosis).

I feel bad for the overpass server though sometimes, making it do these biggish queries. It feels kinder to do big data-crunching on my own machine.

Tree named pubs of London 3 months ago

Blimey. Are we actually just drinking in tree-named pubs?? :-)

Ok ok. Something must be done about this. I've refined the grepping and re-run it to include some tree types: grep -Ei "\btree|\bbush|\bAlder\b|\bApple\b|\bAsh\b|\bAspen\b|\bBeech\b|\bBirch\b|\bBlackthorn\b|\bBuckthorn\b|\bCedar\b|\bCherry\b|\bChestnut\b|\bCrab apple\b|\bCypress\b|\bDogwood\b|\bElder\b|\bElm\b|\bEucalyptus\b|\bFir\b|\bHawthorn\b|\bHazel\b|\bHemlock\b|\bHolly\b|\bHornbeam\b|\bJuniper\b|\bLarch\b|\bLime\b|\bMaple\b|\bMonkey puzzle\b|\bOak\b|\bPear\b|\bPine\b|\bPlane\b|\bPlum\b|\bPoplar\b|\bRowan\b|\bSilver Birch\b|\bSpindle\b|\bSpruce\b|\bSycamore\b|\bWalnut\b|\bWhitebeam\b|\bWillow\b|\bYew\b"

That's taken us from 105 tree-named pubs up to 221. Of these 74 are "Royal Oaks"

Tree named pubs of London 3 months ago

Oh I completely forgot we regularly go to a pub called "The Monkey Puzzle". That's should really count as a tree named pub, which raises the question, what words/phrases for tree species names should be listed out to get a more complete list including names like that. I guess if we include "Oak" then that's going to hit upon a whole load more pubs!

Mapillarising Brazil 3 months ago

Thanks. Yeah I've just about managed to learn how to pronounce it (badly), but spelling Guarulhos is too much.

Mapillarising Brazil 3 months ago

Aye. She was bored back then too :-(

OSM Analytics launched! 4 months ago

Sorry I missed the missing maps event. Good to be able to catch up with a video!

So I was just trying out the tool and bit more, while at the same time making a wiki page for 'OSM Analytics' ...and the screenshot is "Image of the week".

School Edit Tracker 4 months ago

Yeah. A tool like this definitely creates an impression that is a competition, which can be a problem. I think that's something to bear in mind when choosing when to deploy it. There was something about the school project which was almost competition-like. We had a lot of isolated school cases to look through and edit in a fairly clear way which lots of people could get involved in.

Of course there's always lots of ways of gaming the system to score more points in a way which might not be all that helpful, and sometimes in ways which are helpful. For instance with these schools, I noticed somebody could go on a rampage just adding the isced:level tag based on the name of the school. A helpful contribution I suppose, but also an easy way to touch a lot of school objects and win the competition!

My previous uses of the tracker tool were more basic aerial imagery armchair mapping ideas. The wimbledon tennis courts project of the week and my Big Baseball Project. The baseball project had the advantage of being naturally US-focused and so we were only messing up crappy US data (and in 2011 it was mostly crappy data).

For UK projects, armchair mapping concerns are more of a problem. In fact I personally didn't get stuck into editing lots of schools, because whenever I looked at one I ended up thinking "you know I can't actually be sure where the outline of this school is. It really needs to be mapped by somebody who knows it"

What I'd really like is some way of making a competition out of recruiting more mappers. Maybe we could do something like "affiliate tracking links" where if somebody signs up to OpenStreetMap using a link you sent them, then you win! Of course that might encourage people to launch over-zealous spamming campaigns :-/

A missing zoo! 5 months ago

Ha! Doesn't surprise me at all that this was needed. Thanks!

A missing zoo! 5 months ago

oh yeah. Just a Gibbon so far in Perth zoo :-)

Statistical data of the Dutch OSM mappers. 6 months ago

'central way to register' or the welcome messages could just be public. Hence my suggestion to welcome people on their first changeset (use public changeset discussions)

Statistical data of the Dutch OSM mappers. 7 months ago

There's that "Long tail" shape again. I did a whole talk about this at SOTM2014

The welcome program is a great idea. Maybe the effect on the stats would be to "help users up the curve" thereby making the long tail and the elite spike less spiky. Or maybe not. It might also encourage more users to come along, making it longer. Either way, giving new users a good welcome will help build an OpenStreetMap community. It's only logical.

There was some talk of a having an OSMF working group dedicated to the idea, but I don't think it was established in the end.

I wonder whether the new changeset discussions feature might be useful for welcoming people. This is a strange idea really, because just sending an OSM message is more appropriate, but... changeset discussions are public, which changes the dynamic somewhat. What if we establish a convention of welcoming somebody on their 1st changeset? Then we can all collaborate on making sure new users get welcomed in a friendly way without accidentally duplicating messages and effort

Happy 10year OSMversary Maning! Ooh. I'm just noticing mine is coming up next month. It's been a fun 10 years hey?

Should we teach JOSM to first-time mapathon attendees? 9 months ago

We actually used to introduce people to JOSM from the get-go a lot more than we do now. Certainly at humanitarian events I've organised before Missing Maps started. In fact there was one back in 2010 where I had no choice, because we needed WMS-supplied imagery. And on that occasion it was bit of a nightmare. Thankfully things have moved on a lot since those days (most of the JOSM UI issues I mentioned there have been fixed since, and we're better at finding ways of not using WMS imagery) Even at the first few Missing Maps events, we followed the approach of presenting the choice, but then demoing the install of JOSM, or asking people to come with JOSM installed.

Why did we move to a more iD-ish approach? I think we used to have a very high proportion of absolute beginners, and some early experiences of mapathons, put us off JOSM a bit. It felt very chaotic as >50 people started downloading JOSM for the first time (the download itself can immediately create an internet bandwidth issue for a start) and then asking questions about how to install on different operating systems and versions of java!

But yeah I've always said, new users are actually better off going straight to JOSM, for a better more fluid editing experience. BUT.... certain types of new users will find it easier. As Pete says, "people who deal with any / many types of software professionally", which is probably at least 50% of the new folks coming to these events actually. So the thing is, depending on this proportion, and the number of experienced people you have on hand to help... getting lots of beginners started on iD can be a lot easier for event organisers. With iD you can write out instructions which will work for everyone, and these will fit on one piece of paper.

Via Monte Napoleone 9 months ago

I like it! In fact I've just made it OpenStreetMap "image of the week" this week! http://wiki.osm.org

I get why so many people just don't bother to even try to vote for the OSMF when things like this happen 9 months ago

Yeah. You do need to vote before the (very clearly stated) voting deadline. Sorry :-(

OpenStreetMap and Humanitarian OpenStreetMap Team Together 9 months ago

It's long been observed that different people get different things out of OpenStreetMap, and have different ways of expressing their motivations. Of course some of us are intent on using OpenStreetMap just for a for a sat-nav application in Los Angeles, while others are using OpenStreetMap just for an immunisation programme in Lubumbashi. You say "OSM is about the process of collecting data and sharing knowledge". But knowledge of what? In what form? Perhaps a good way of describing it would be... it's knowledge in the form a "free and open licensed map of the world" :-)

I agree though, that it would be wrong to say we are only succeeding in our goals if we are managing to map the whole world. Wide coverage, reaching into every corner of the globe isn't necessarily the primary focus of the project. On an individual level we encourage people to focus on mapping their neighbourhood. On a project level, achieving wide coverage... I would say it is an important success metric (and one we are succeeding at!) but yeah... not the only success metric.

Certainly we are building a "free and open map of the world" if we only take it to mean the OpenStreetMap system of edibility, data representation, and community building can work the same worldwide.

Unknown Pleasures (of humanitarian mapping) 9 months ago

It's "image of the week this" week! http://wiki.openstreetmap.org/wiki/Main_Page

Wanted: Simple amenity describer and foursquare style Q&A process 11 months ago

The Kort game http://play.kort.ch is designed to be asking various simple questions. Maybe it could do with some more interesting questions related restaurants and pubs (making it more foursquare-like) For me it's just asking relatively uninteresting questions about name language settings on things and names of service roads, so some questions about extra POI tagging might liven it up a bit.

Of course WheelMap http://wheelmap.org/en/ is everybody's favourite example of an nice narrow focussed tagging app. Essentially it's asking one question... "how's the wheelchair access?".

Likewise coffeedex https://www.mapbox.com/blog/coffeedex/ just asking "how much does coffee cost?"

onosm http://onosm.org is for adding new things to OpenStreetMap, so not really the foursquare-like thing you're describing, but a simple tool with a constrained set of fields.
