|What does the path say?||about 1 month ago||
Richard, I love this post :-)
highway=path was a stupid, completely pointless invention that has served to make the data less useful, not more.
|MapBBCode: free maps for everyone||about 1 month ago||
Ah, got it, thanks.
|Light up my way! (First Anniversary)||about 1 month ago||
Very impressive, how did you cover such a large area checking for street lighting?
|MapBBCode: free maps for everyone||about 1 month ago||
This is fantastic, thank you.
Where can you add labels to polygons, as in your second screenshot?
|What is the OpenStreetMap convention? Do we tag addresses on buildings or on separate nodes?||about 2 months ago||
One reason I prefer to add the address to the way is that I also add the other tags - amenity, building type, etc. to the way. Adding a separate node then requires somebody using the data to step through an extra hoop to find the addresses for those amenities / buildings.
This step isn't that hard for somebody familiar with spatial joins in some proper GIS software, but plenty of people like to just link to an object on the web site to say "this is where we're meeting", or download a simple extract from XAPI/Overpass.
|Artwork : only for tourists||about 2 months ago||
It was also quite funny when we got the proposal for tourism=gallery through for art galleries. Some people thought there was no need because we already had art shops and museums.
Somebody did suggest a great big revision of tags under a "culture" key, but it got nowhere because, like all great big revisions, it would only lead to an even bigger mess of old and new tagging systems.
|A Social OpenStreetMap.org Without Groups||2 months ago||
I'm not up to scratch on coding with ruby to be able to interpret the pull request Mikel pointed to, so apologies if these points are covered.
I want to know if the groups, or topics, go beyond just social stuff to actually provide some useful tools? I already mentioned some of these but you haven't picked up on them in your responses...
Maps showing relevant data - could just be an interface to create some calls to overpass, also point to custom tiles for a map on the group page
Some way of linking up with wiki pages, or a wiki facility built in, to gather useful resources, e.g. a "buses in London" group/topic might want to highlight the NOVAM bus stop tool, the ITO bus priority map and others
This kind of stuff isn't very exciting to people who find it easy to roll their own custom map and use the wiki. But it could make OSM quite useful for less geeky audiences who are interested in adding data they are interested in to the database.
|A Social OpenStreetMap.org Without Groups||3 months ago||
I'd like to echo Richard's comment in particular. Alex, I think you are talking about a vision for groups as some sort of duplication of Facebook, which I think misses the point. I don't want to become best friends with people who happen to share my interest of mapping south east London, the natural world and cycle infrastructure. I just want tools that make that job easier, and that encourage people with similar interests to get involved with mapping them.
When Richard gave his talk on groups I wrote this blog post explaining this point further: http://tom.acrewoods.net/2013/06/12/getting-enthusiasts-into-openstreetmap/
Groups shouldn't just be about a message board, though I'm sure for some groups they will be really valuable. Groups could help communities of interest (be they locational or thematic) to do things like:
I'm sure there are other group features people could dream up. I'm quite excited by the momentum behind this, and I'm not surprised it doesn't excite people who already feel quite well served by the infrastructure we provide to uber-geeks and map obsessives!
|It's amazing how far sixteen lines of c++ can get you.||3 months ago||
Great stuff. You're trying to put me through the fun of setting up OSRM, I see.
Although it only covers the Greater London area, you can use the same process I described in my blog entry to map average nitrogen dioxide concentrations onto the OSM linestrings. That will give you a complete dataset covering every road, path and monkey puzzle tree in the capital.
The same dataset (the LAEI) also contains data for particulate emissions, which would help in central London. In town the NO2 concentrations are basically way over the legal limits everywhere, but the particulate emissions are concentrated on main roads, so you could still find a slightly less bad route.
Anyhow, if someone did fancy taking this further, I think there would be interest in, for instance, helping schools to plan healthier walking routes.
|New contributor experience||4 months ago||
Yes, welcome and good feedback! Thanks.
On your first issue, I think it is a bit slow at the moment because we recently switched the technology that renders the maps, and I think it is taking some time to clear a backlog:
|A la découverte de la carte Ouverte de Rennes||5 months ago||
Bonjour, je suis desole pour mon mauvais francais. J'ai cree cette carte systeme a afficher les trait verts a partir OpenStreetMap sur la carte. Et le systeme cree des fichiers KML et GeoJSON pour votre website.
Votre projet est tres bon aussi!
|OpenStreetPOIs||5 months ago||
Nice work, you might also be interested in the method I use for OpenEcoMaps:
This takes data from the Overpass API and pulls out features whether they are nodes, ways, or relations, turning them into GeoJSON and KML files.
|Using OpenStreetMap on a daily basis||5 months ago||
As much as I would love to see a decent routing framework plugged into our homepage, I do wonder how much it would drive up the number of contributors (excluding those who make one or two edits then never return). Clickable POIs probably have more potential.
It's nice to say people should offer their help to people with good ideas, but we have finite energy, time and money to throw around. Which of the good ideas would have the biggest impact?
What we most need are enthusiasts, and their 'consumer' needs can really be quite varied. Often your average OSM mapper won't have the first idea what another person's needs are, what will turn them and their community of interest onto OSM. Richard Fairhurst gave a good presentation on this point at the SOTMUS conference, and I wrote some more following his talk.
I bet that even with Google Maps the number who report fixes or fire up Map Maker is less than one tenth of a per cent of all the map users. But if we made OSM genuinely useful (and easy) for ramblers, cyclists, conservationists, accessibility campaigners, local government officers, sailors and more... well then we would gain lots of enthusiastic contributors. So what do they need? Let's find out, and then as you say, no more "no's"!
|Leytonstone looking slicker||5 months ago||
That looks like some great work, it's a shame that the default Mapnik stylesheet doesn't yet support some of the features you've added.
|Mapped UK addresses by postcode area||6 months ago||
Thanks. A few things I noticed:
|Problems with landuse||6 months ago||
I left a few questions on your list.
My general comment is that with many of your comments you are trying to find a perfect solution for an imperfect, complicated world. You mention the wood/forest tags, which is a classic example where nobody can agree on a definition to clearly distinguish between the two. As you say, how much woodland is there that is really untouched by humans, and how much forest for that matter? The wiki pages do touch on the different ways that people treat them. With our current system of free tagging and consensus emerging from chaos, there is no way to resolve this and proposing new tags only confuses the situation further.
|New Keypad-Mapper version 3.1 released||6 months ago||
Markus, I've been using this app, thanks for the work on it.
One quick request - could you include a feature to add addr:flat values? Currently I just add this into the housenumber value and then have to manually split it out. For example, I enter "15,a-c" which becomes:
But it's quite time consuming doing it this way.
|Adding addresses: NG9||6 months ago||
Will, thanks for the responses. I don't know that I'll ever match your work ethic, though! It took me five years to complete two London borough wards, and since moving from that area I've been much slower in gathering addresses for my new suburb. The numerous flat conversions make data gathering and entry slow, and the many extensions and odd houses on bomb sites even makes tracing to a reasonable quality laborious and boring.
As you say, it's fiddly, time consuming and complicated. Much less fun than the good old days when I was faced with a blank slate in Reading and got to whizz around on my bike just adding streets, post boxes and pubs!
|Adding addresses: NG9||6 months ago||
Wow, that's some very impressive (and as you say time consuming) work!
On interpolation, I added addr:interpolation=odd where I had buildings such as a block of flats containing numbers 11, 13, 15 and 17 but not the even numbers in between. Somebody came along and removed all of those - nice of them - because apparently that's not the done thing. But it left the addressing quite ambiguous. Can you clarify what you have done in these situations?
I get a bit stuck on flats. For example, a building with flats 1, 2 and 3 is easy enough (addr:flats=1-3), but what about a building with flats "23, 23a, 23b"?
I have never really got to grips with suburbs, though it has been discussed quite a few times. The main problem I have is that the bounds of different names are very subjective, and infamously dependent on whether you speak to a long-term resident, an aspiring incomer, an estate agent or a ward councillor! So I have just ignored the whole thing, and quietly ignore the hapless attempts of Nominatim to give context to a street's location.
Could you also explain a bit more clearly what you did for the school, or give a link to the OSM object?
|Mapping Croydon||7 months ago||
Matt's tool compares the Land Registry entries to OSM, and lists them as missing (i.e. an object with the address exists in OSM but not with the post code), no match (i.e. no object found in OSM) and perfect match.
You can pretty much copy over every post code in the "missing postcode list" to your OSM objects.
The convention on other sources is that it's ok to take a post code off an individual business' web site or in-store literature, but not to start copying them out of a compiled database like the pub listing web sites.
