Notes and Fixmes

Posted by SomeoneElse on 22 December 2014 in English (English)

A while back I wrote https://github.com/SomeoneElseOSM/Notes01 to enable OSM notes to be converted to a useful Garmin format so that you can actually check them when out and about.

A week ago I added support for extracting "fixme" tags from Overpass. There are about 20 notes within 9km of my house, so I was interested to see how many fixmes there were. It turned out that there were 430! As someone said on IRC, "that'll keep you busy over Christmas".

Best Regards,

Andy

Mapillary 3D navigation tech preview

Posted by Peter Neubauer on 22 December 2014 in English (English)

Hi there,

I'm pretty excited about Mapillary starting to approach large scale 3D reconstruction of places and cities. To start with, this will be used to correct bad GPS traces, but also to make a whole new generation of navigating images in space and time possible.

Think of it as a crowdsourced photosynth with free navigation and totally dynamic filtering for users, time and other parameters as a first step. I think this will further make a very positive impact for everybody using OSM and Mapillary for getting high quality information out.

See the Mapillary blog entry for full details. Feedback is very welcome!

Editing with Overpass and Level0

Posted by escada on 20 December 2014 in English (English)

Recently I noticed that the links that I have been using for heritage:website in Flanders were broken. Since this has been going on for a couple of weeks, it is not just a temporarily hiatus, but a permanent problem. So I have to update them all.

The old format was http://para.ms/relict/<relict-number>

The new URL is https://inventaris.onroerenderfgoed.be/dibe/relict/<relict-number>

First, I use an Overpass query to find all those listed buildings.

Result of Overpass query

Overpass allows you to open the result in an editor, e.g. Level0.

Export from Overpass

Level0 is a "simple" editor that allows you to edit OSM data

The data in Level0

The editor is so simple that there is no find+replace functionality. So I copied all the data into a text editor on my computer. There, I replaced the wrong URLs with the correct ones. This is a straightforward operation on any text editor. Then I copied all data back into the Level0 editor.

I logged into OSM. You can find the login button just above the data section, on the left. I confirmed the OSM dialog in order to allow Level0 to use my account

Level0 account confirmation

The result is that Level0, now knows who I am Level0 knows how I am

After filling in a changeset comment the data is ready to be uploaded Updated data and changeset comment

is this a mechanical edit ? Not for me. I added at least 90% of those URLs myself. I checked several URLs myself and found that none of the old URLs were working anymore. So for me this is just a resurvey of data.

I also used this principle to update some fire hydrants that I added without specifying the type of the hydrant. This mechanism was also used to add some wikidata numbers to administrative boundaries in Belgium. Since I manually looked up the wikidata, this was not a mechanical edit neither.

I admit that this can be used to perform mechanical edits, but nevertheless I consider it as a powerful tool to quickly edit some incorrect data.

Potlatch 2: quickly move from task to task

Posted by Richard on 20 December 2014 in English (English)

Task-based fixup workflows, such as MapRoulette, To Fix, and the HOT Tasking Manager, have become popular in OSM in recent years, presenting a series of map-improvement tasks for a user to complete.

MapRoulette is wondrous in many ways but has three issues. First, if you're using an online editor, the time taken to open each task is significant - around 3-5s to open a new instance of iD for each task. Second, that online editor has to be iD, so it's not suited for those of us who use P2. Third, the process for creating your own tasks is fairly cumbersome, especially if you're working on a small series of tasks to be completed by one or a few people.

Potlatch 2 now implements a fast, light way of moving through a series of tasks. It's intended for small-scale personal work rather than planet-sized challenges. There's no 'resolve' button - it's just a way of moving between locations efficiently.

It works like this:

Create (or find) a GPX or GeoJSON file containing the locations.

If it's a GPX file, it should contain waypoints. Each one can have a description in a <desc>, <cmt>, or <sym> element.

If it's a GeoJSON file, it should contain Point features. Each one can have a description in the 'name' property (or, failing that, the first property).

Open it in Potlatch 2 with the Tasks button.

Potlatch 2 Tasks button

You can either load a file from disk, or type a URL and click 'Fetch URL'. (For the latter, note that the usual nonsense about needing a crossdomain.xml file at the root of the server applies, sadly.)

Move from task to task with the palette.

Potlatch 2 Tasks palette

The map will centre on the first location. When you want to go onto the next one, click the forward arrow. To go to the previous one, click the back arrow. And that's it.

Try it for yourself using a GPX file of waypoints. If you don't have one to hand, these files from the Adventure Cycling Association of long-distance cycle routes across the US are fun.

I'd be interested to hear of other formats this could support, and further suggestions for improvement; and it would be lovely if authors of other editors were also interested in exploring the idea.

Rising participation in the discussion of tag definitions

Posted by jgpacker on 20 December 2014 in English (English)

The tagging mailing list is seen as the main place of discussion when dealing with tag's definition.

However I feel that a mailing list is no longer an appropriate place for that. The tagging mailing list often deals with very specific topics, which most people aren't interested in. The result of this is that a lot of people that could bring value to specific discussions are not subscribed to the list and therefore have a hard time participating because joining such a high traffic mailing list is not worth it to them.

My suggestion is: Let's move the tagging discussion to a forum! This way people can pick some topics they are interested in and discuss to their heart's content without bringing hundreds of email copies to people that aren't as interested. Besides, everyone can participate.

Cheers, John

OSMaPaaralan

Posted by GOwin on 19 December 2014 in English (English)

It's a day short of a year since OSM-PHL got a letter from the Philippine Department of Education (DepEd) allowing us to incorporate some attributes of their school database into OpenStreetMap.

DepEd's name for their project "maPaaralan" is a portmanteau of Map+Paaralan (Filipino word for school). I hope to revive this effort and see where we stand right now. The original discussions are here

I promised myself to contribute on more local projects next year, so I hope to make OSMaPaaralan as my first such project for 2015. See my OSMaPaaralan workplan

P.S. Hah! It appears this is actually my first diary entry, too. :D

Lanes and turn:lanes

Posted by escada on 17 December 2014 in English (English)

One of the projects I have been working on since April this year, is adding lanes & turn:lanes information to all motorways, trunk roads and primary roads in Flanders.

The work is far from finished, as you can see on Missing lanes in Flanders

Reqruiting new mappers for Missing Maps & HOT

Posted by anders_ar on 16 December 2014 in English (English)

I held the first of a series of introductions to OSM today, for my employers members of EWB (Engineers Without Borders).

A great turnout, with 25 people turning up to listen at the head office, and several others tuning in via our video conference system. A great start! Even better, when asked if they wanted to contribute after the presentation, close to everyone was interested. A good promise for future mapathons in the Oslo area and rest of Norway. The presentation was a little bit of everything, since we had only 30 minutes available. We covered topics such as different uses for OSM, where I presented my favorites in terms of mountain biking and historical mapping, and transitioning into humanitarian mapping resources and what we can achieve with very little effort.

Shoutout to Pete Masters and Nick Allen for helping out with some advice and links to good presentations and other material from Missing Maps & HOT, really useful.

Next time we will be addressing actual tasks in the HOT Task Manager, can't wait to get started.

London Missing Maps Mapathon December

Posted by Tallguy on 16 December 2014 in English (English)

Ho, Ho, Ho

Antlers, what a good idea. If you want to break the ice & chat with a bunch of nice people, try wearing antlers. I hope I haven't given too many people my cold - honestly, it's just been a little nuisance until yesterday when I nearly lost my voice.

I'm certain that the Missing Maps Team deserve a brilliant Christmas for all the hard work they put in making these events run so smoothly - It's a pleasure to work with you guys & Thank You. I'm including all the HOT people who turned up to help - brilliant, you're advice (and waiter service delivering mince pies) is invaluable.

Great progress folks - I can't wait to see the full stats when you've all finished any squares you were working on, but 34% done during the course of one evening, and many more squares started & just needing a little more work - that's impressive!

Impressive stats folks

I'd like to see all of you at future mapathons, it's always amazing how quickly people progress - if you'd like a little light reading, have a read of LearnOSM section for Remote, Armchair or Mapathon mappers which aims to helping you with everything you will need to map remotely for these tasks. Personally I find it displays quite well on my phone.

LearnOSM is something I've become deeply involved in now - it's the 'HowTo' for many things that the Humanitarian OpenStreetMap Team - HOT promote, so it includes many sections on how to map, how to use JOSM & iD, and for NGO's how to extract & use the data that OSM produces. It's worth spending time delving around in there - there's so much information that no index is ever going to do it justice - you just need to spend a little time delving around.

A little help please.

  • It would be really great if you could finish the squares you started on - it's much easier for you because you know what you did, and what's still to be done.
  • If any of you have got photo's of buildings, huts, roads & any of the other structures that we are mapping in Africa, and you can release them to HOT with no copyright restrictions so I can add them into LearnOSM it would be very helpful - a picture says a thousand words.
  • Translation of LearnOSM - always welcome if you fancy having a go. Links are off of the site (click on the pencil). It's amazing how many people all over the world want to help, and if we can give them the information in a language they can understand it makes a big difference.

Have a Happy Christmas & a Terrific New Year,

and I hope to see you all again in the future at another event.

Nick - the Tallguy with antlers, bald head & a cold!

The past year and a half in review

Posted by skquinn on 16 December 2014 in English (English)

The vast majority of my changesets have still been in and around Houston. I've made various other fixes around the country, sometimes related to notes, sometimes at random, and in a few cases from a trip I made to/from greater Columbus, OH.

With the help of others, a sizable amount of the traffic signals are now mapped in and around Houston. I've also found a few roads that should be tertiary or better that had been left as residential or unclassified. My focus has shifted between road features themselves to building outlines, points of interest (POIs), address data, and occasionally land use if I can see a large parcel of land with e.g. nothing but trees on it. Occasionally I'll map stop signs if I know the area well enough but it can be a considerable pain due to the direction tag required.

I'm now serious enough about mapping that I've switched to JOSM for the vast majority of my editing. I still use iD for the occasional simple edits or when I'm on a computer without JOSM installed, or sometimes to edit turn restrictions. Dualizing roads in iD was a real chore. Actually, it's extremely difficult with iD by itself; usually I would switch to Potlatch 2 at least to add the actual parallel way. The only reason I stuck with the online editors is that my first experience with JOSM was on a computer I had no business trying it on (an old PC with an 800MHz Celeron CPU and a whopping 256M (0.25G) of RAM) with predictable results. The nice things about JOSM that I consider most notable are:

  1. It's Java, so it runs on just about any computer regardless of operating system (one less reason to dread ditching Windows).
  2. You can add plugins to make certain tasks easier (I have one specifically to speed drawing rectangular building outlines).
  3. JOSM has tons of additional features that wouldn't be possible or practical in an online editor.
  4. The parallel ways tool is much easier to use than the one in Potlatch 2 and makes a more complete copy of the way (nodes with traffic signals, crosswalks, etc. are tagged on the new way). Note: this is mostly good but there are cases where it can be a problem as well.
  5. The response time of JOSM is much faster than iD ever will be on the same hardware. This is especially true when editing areas like downtown Houston.
  6. JOSM has search and replace functionality. If, for example, someone added a bunch of McDonald's locations, and misspelled it MacDonnold's or something equally hideous, it's easier to fix and your chances of swearing while doing it are at least a factor of 10 less. Also good for finding and replacing non-conforming highway references (say, the lone SH 6 when everything around it for miles is TX 6) and for quickly de-abbreviating streets (search for "W 1st Street", edit name tag to "West 1st Street" once even if split into 20+ ways aka "road chop suey").

That said, iD and Potlatch 2 have specific roles that they are best at filling. There will always be people who don't want to learn JOSM and are happy using iD (or even Potlatch 2). That's fine, and I believe in having choices so that each mapper can decide for him/herself.

Nominatim Search in OSM-IQ

Posted by marco79 on 14 December 2014 in English (English)

The new Version of OSM-IQ 2go uses the Windows Search contract to integrate a search using Nominatim. This way you can use the Window 8 charmbar to search for a place in the Open Street Map database.

Nominatim search in the charmbar
