"Just watch Taginfo" - doesn't work at all outside En community

Posted by d1g on 11 November 2014 in English (English)

(Please forward this text to right person or place)

There are a lot of problems outside En community when it comes to OSM guideline "just watch Taginfo for popular values". This approach work more or less for EN community, but users outside English-speaking world faced with the challenge to realize the word, not local word with similar letters\sounding.

I do Russian translation at wiki\ID\communicate with ru community and many ru users do no realize that reading tag values by letters in Taginfo doesn't work without meaning of the word. it may sound absurd, but it is not written anywhere. Instead we (English speaking world) promote "just watch the most popular values in Taginfo ". This is serious issue outside GB, USA, Canada, Australia. We have way more countries. Even more if OSM want to grow.

  1. Promote OSM wiki instead of Taginfo across all non-English languages. Possibly notice should be given at langcode:main page@wiki or every single wiki guide/content should be rewritten.
  2. Not Taginfo fault, but Taginfo can fix this. Just add feature to Taginfo to directly show wiki-translated page based on "Accept-Language" header. Force this behavior by default for not-English languages. Yes, '''force displaying wiki pages parallel to previous Taginfo interface'', but let users switch language (and disable this feature).
  3. Everything for English-speaking world stays the same, since this is main language/tagging convention, there no need in changes for GB/USA/Canada/Australia.

OpenStreetMap - yours to cut out and keep

Globes, gores and geojson (topojson)

osm-world

Been thinking about this for a while. Like maybe two years. How do you make a globe using openstreetmap data? So when I say think, I mean a quick way to hack this together using lots of other peoples hard won code.

According to what I could find, the main thing was to create 'gores' these are the name of the thin oval shapes that make up the outside edge of the classic 'orange' segments.

So I googled it a while back and found a perl script for Gimp that appeared to do the trick. At the time, it seemed very involved and I hardly knew much about writing scripts etc (although reading about again - it now seems more straight forward). So I put the idea on the back burner for a while

The next approach seemed to be using Generic Mapping tools (GMT). Which also has a way to stitch gore projections together. But the first time I attempted using GMT, I had issues installing it. Once I got it running it has a bit of a learning curve and lots of interesting file formats...After a short battle, I abandoned my attempt at trying to get it to work.

So it would be nice to do in QGIS using the proj4 library. But unfortunately, it doesn't work for gores like projections. In the business they are called 'interrupted' projections because the map is not just stretched but split into pieces. It is possible I believe to project one gore at a time and stitch together (sounds like a python script waiting to happen).

By this time, I'd spotted a javascript plugin for D3 that looked promising call d3-geo. Seriously, go there straight away and look at it. Recently a projection called 'gingery' was added. Again, go check it out.

Anyway, the d3-geo has lots of examples and it was easy to use or maybe my knowledge is somewhat more advanced now. It was possible to tweak the examples and see how they work. Although the core projection mathematics is still way out of my league. But thanks to Jason Davies and Mike Bostock who created them - absolutely amazing.

The next stage was to get some OpenStreetMap data. But that was no problem, using openstreetmapdata.com (thanks Jochen Topf). This gave a shapefile of the basic global land polygon using OSM. I decided to simplify this using QGIS - but this step is not really necessary. After simplifying I was left with a file called simpleworld2.shp but D3 required topojson format. So on a linux type system, first you need to installed Node.js (I had this already), then install TopoJSON:

npm install -g topojson

then using the topojson guidance I used this command

topojson -o output2.json simpleworld2.shp

Converting to topojson greatly reduces the file size. You can now reference the output2.json file within the example given on the d3-geo site.

If you want my html/javascript example, osm based world topojson file or the svg of the above image see my repo here

Now get busy with staples and glue!

p.s. looks like there are other ways using Wolfram / Mathematica/ Matlab examples.

Only with OpenStreetMap: how Caminos de la Villa puts poor neighborhoods in Buenos Aires on the map

Posted by lxbarth on 10 November 2014 in English (English)

Attendees of State of the Map in Buenos Aires this weekend may have noticed how Buenos Aires' villas de miseria - poor precarious neighborhoods - are well mapped on OpenStreetMap.

It's a great example of how OpenStreetMap enables citizens to just create the map they need: The initiative Caminos de la Villa holds government accountable for public services in low income neighborhoods. The problem was, when the program started, Buenos Aires' villas weren't on any digital map. So the teams behind Caminos, the Argentinan technology non-profit Wingu and the social justice group ACIJ rallied a group of locals and put five villas with a total of 27,000 families on the map.

Over the course of 6 months they spent a total of three weeks tracing and surveying the five villas. The result is 638 ways and 102 points of interest added. This was tremendously useful work done in an incredibly short amount of time.

OSMF Board voting extra statistics

Posted by Zverik on 9 November 2014 in English (English)

Richard is now counting some stats on anonymous ballots from the Board voting, and he persuaded me to publish some other, more complex stats I did on that Saturday. So, here comes.

Basic counting

Out of 219 ballots...

  • 79 (36%) have all 8 candidates ranked
  • 56 (26%) have 3 candidates
  • 23 (11%) have 4 candidates

Richard makes a smart assumption that some people didn't quite understand that one can submit any number of candidates, not one, not 3 (for number of seats) and not all 8. I submitted 4 candidates, because I had strong preference for Board members, and I believe that's the case for most of 3/4 votes. And people who filled all 8 positions maybe are not happy with a tiny chance their vote will be burned otherwise.

Every candidate has been listed at each of 8 positions in ballots (that is, there is no candidate that haven't been assigned e.g. #6 in at least one ballot).

For ballots with less than 8 positions, some of the candidates were not mentioned. Let's count number of ballots for a candidate, where he/she is not included:

  • 102 (46.6%) — Steve Coast
  • 93 (42.5%) — Ethan Nelson
  • 80 (36.5%) — Randy Meech
  • 75 (34.2%) — Marek Strassenburg-Kleciak
  • 73 (33.3%) — Paul Norman
  • 64 (29.2%) — Peter Barth
  • 54 (24.7%) — Kathleen Danielson
  • 39 (17.8%) — Frederik Ramm

So, nearly half of voters skipped Steve (I wonder why) and Ethan (probably because he is less known than others). Frederik and Kathleen wrote a lot of good, thought-provoking posts in osmf-talk, so I hope that's why everybody were voting for them.

Second places

We know Frederik Ramm got 78 first-rank votes, and 23 of them were distributed among other candidates. Whom?

  • 27 (35%) have chosen Peter Barth as the second candidate, so he got 8 of these extra votes
  • 19 (24%) have chosen Paul Norman, so he got 5.6 votes

(The rest was skipped because numbers are too small). Some of those who gave the first preference to other candidates had very strong preferences for the second place:

  • 11 of those who voted for Paul (55%) have chosen Frederik as the second
  • 12 of those who voted for Randy (52%) have chosen Kathleen as the second alternative

So it's quite clear why when Randy Meech was eliminated at round 5, Kathleen was immediately elected for the second seat at the Board.

What if...

Now, what if we didn't use STV, but went for the first preference? Here are [some of] first candidates ranks:

  • 78 (35.6%) — Frederik Ramm
  • 32 (14.6%) — Steve Coast
  • 30 (13.7%) — Kathleen Danielson
  • 23 (10.5%) — Randy Meech
  • 20 ( 9.1%) — Paul Norman

You see a bit of difference with final results (Frederik, Kathleen, Paul). So, if there were 4 seats to fill, who would take it — Steve or Randy? Guess again:

  • 4: Peter Barth
  • 5: Steve Coast
  • 6: Randy Meech
  • 7: Marek Strassenburg-Kleciak
  • 8: Ethan Nelson

The magic of STV! Of course, next preferences played a big role in the actual result. Let's see who was most often mentioned as a backup candidate:

  • 43 (19.6%) — Kathleen Danielson
  • 41 (18.7%) — Frederik Ramm
  • 35 (16.0%) — Paul Norman
  • 32 (14.6%) — Peter Barth

Here they are. Let's invent another voting system, where the first candidate gets ½ of a vote, the second — ¼ of a vote, the third — 1/8 and so on. What the results would be?

  • 52.5 — Frederik Ramm
  • 31.5 — Kathleen Danielson
  • 24.9 — Paul Norman
  • 22.9 — Peter Barth
  • 21.6 — Randy Meech
  • 20.6 — Steve Coast

This is where it gets complicated

Why the 5th and 6th candidates differ from STV results for 6 seats? That stems from placements variation. Let's find a most assigned rank for each candidate. For example, Frederik was placed first in 78 ballots, and second in 41.

  • Frederik Ramm: 1:78, 2:41
  • Peter Barth: 3:41, 2:32
  • Marek Strassenburg-Kleciak: 3:28, 4:23
  • Randy Meech: 3:24, 4:24, 1:23
  • Kathleen Danielson: 2:43, 1:30, 3:29
  • Paul Norman: 2:35, 3:34
  • Steve Coast: 8:44, 1:32
  • Ethan Nelson: 5:28, 4:25

That list is hard to read, so let's erase the ballot count:

  • Frederik Ramm: 1, 2
  • Peter Barth: 3, 2
  • Marek Strassenburg-Kleciak: 3, 4
  • Randy Meech: 3, 4, 1
  • Kathleen Danielson: 2, 1, 3
  • Paul Norman: 2, 3
  • Steve Coast: 8, 1
  • Ethan Nelson: 5, 4

Steve's positions are interesting: mostly first and last ranks. Frederik is most favored, so 1st and 2nd ranks mostly. Others float around their ranks, not deviating much. Voting results basically reflect that: Frederik, Paul and Kathleen are closest to the top ranks, with Peter following.

Classified

We haven't got permission to publish number of normal and associated OSMF members who voted and who were eligible to vote, but we can make some assumptions from the statistics and number of ballots.

  • Members: normal + associate = total
  • By October: 182 + 336 = 518
  • Eligible: ? + ? = around 300 (518 minus 218)
  • Voted: 106 + 113 = 219

So if we take number of voters for 73% of those eligible, we get following numbers (again, they are very approximate):

  • Eligible: 145 (of 182) + 155 (of 336)

Which means that nearly half of associate members are behind on their membership payment, while most of normal members pay on time. The question is, are they behind because of financial troubles, or because they don't care. If it's the former, then the new policy on associated membership fees would help a lot.

Mapillary Bike Ride in my Neighborhood

Posted by ElliottPlack on 9 November 2014 in English (English)

Imgur

This week I had an off day and decided to get some exercise. It is hard for me to even think about working out anymore without also considering mapping. Ever since Strava started using OSM for its routing engine and for exercise maps, I've been motivated to use it because a) Strava is a lot of fun, and b) I like contributing back to OSM with it.

Enter Mapillary

A new player in the OSM space that I am enthusiastic about is Mapillary. Mapillary is a service / app that allows users to shoot their own street-view imagery, and use it for OSM without fear of licensing issues. The typical use would be to attach a camera to a personal automobile and shoot street-view, but it works on a bicycle as well.

Bike Mount

Since I enjoy touring around on my bike, I thought it'd be a great to get some Mapillary images at the same time! I purchased the Topeak iPhone 5 Mount and attached it to my handlebar. The Topeak mount comes with a special case, and it can hold the iPhone in practically any orientation.

Tuesday's Canton Ride

Driving around a neighborhood in a car seems boring to me, and is a waste of fossil fuel. On the other hand, exploring a neighborhood on foot or on a bike is fun and healthy. I decided that I would survey as much of my neighborhood as I could during the course of an afternoon with my Mapillary bike mount. It made for an interesting GPX track!

Imgur

Seeing the track as a workout on the Strava iOS app, which uses OSM data via Mapbox to create the tiles was also cool to see:

Imgur

In the end, I covered 16.5 miles without ever leaving my neighborhood, and rode in at least one direction on every street within the area I planned to survey.

Lessons Learned

Riding around on the bicycle and shooting Mapillary is fun! There are some limitations to using the iPhone app for capture though.

  1. The battery. My old iPhone battery does not last long. I brought a backup battery charger for this reason, though it did come disconnected a few times, causing me to have several segments on my trip. Luckily the app doesn't seem to lose data when the phone dies.

  2. Rolling shutter blur. Unfortunately, the iPhone camera suffers from motion blur (see below) when using it as an action cam. The a jolt from a bump in the road can cause a section of the image to look blurry. The only work around for this is to get a better action camera, or get a better action camera, like the GoPro or Garmin Virb.

Mapping

Once the data is in Mapillary, it is really beneficial for mapping. Now users can view the images right in iD, as I did in the screenshot below. I have already fixed some incorrect roads in the neighborhood that I hadn't noticed before. With my images I was able to clearly see the street name, and where it ended based on the GPX.

Now get out there, get some exercise, and get mapping!

Long and possible incorrect street names in Russia?

Posted by karussell on 7 November 2014 in English (English)

I'm running world wide imports for the route planner GraphHopper and due to space savings I allow street names with a maximum length of 255 characters. This was all fine until a few months. Now I get lots of lengthy stuff in Russia - possible automated imports? What is going on there and should one fix this ugly stuff? If yes, how? I can find out the way ids if someone is interested.

Interview: Mapper of the Month (Belgium)

Posted by escada on 7 November 2014 in English (English)

The Belgian community wants to put each month another mapper in the spotlight. The reason is that OSM would not exist without mappers. This mapper receives the title "Mapper of the month" and gets the chance to herself/himself through a small interview. There are not really criteria to become a "mapper of the month", besides that you map.

On the Belgian website http://osm.be you can find the article in Dutch and French together with some pictures.

Since we do not have an English section (yet) and I made the translation anyway, I decided to post it here. I hope you enjoy reading it.

Mapper of the month: Ben Laenen

Ben Laenen, in OpenStreetMap known under the username Eimai (pronounce /ˈimɛ/ like the Greek word είμαι), lives in Antwerp and is in his daily life a train conductor. During his studies he became active in the FOSS-world, now already a time ago. He is for example one of the people responsible for DejaVu Fonts, one of the standard fonts in several Linux distributions. The same font is also used in the main rendering engine of OpenStreetMap, Mapnik. As such, he is also active in the Libre Graphics community, more specifically in the typographic aspects.

How and when did you discover OpenStreetMap?

Suddenly OpenStreetMap was one of the projects that got additional attention from the open source community, which I already followed because of my involvement in DejaVu Fonts. I started to map in 2007, when there was almost nothing mapped in Belgium and the OpenStreetMap community was only a handful of people. As a little boy I was already interested in all kinds of maps. I could spend hours looking at atlases and printed maps. I even drew imaginary street maps myself. OpenStreetMap must have stirred up my interest in maps again!

How do you use OpenStreetMap?

Of course I use OpenStreetMap to plan my trips on a desktop computer, and with OsmAnd on my mobile phone, in Belgium and abroad. Professionally, it comes in handy, as railway installations can have quite complex structures and mapping those structures helps me to visualize them. Of course, we have the technical plans, but a view with the exact location of the rails is also very useful.

What kind of mapper are you and where are you mapping?

Currently, I belong to the category of armchair-mappers, so mainly using aereal imagery to map. But I try to verify what I map! When I go outside, I mostly go by bike, armed with a GPS and a voice recorder. Normally I edit within Belgium, although I edit abroad as well when a trip brings me over the border.

What do you map and do you have any specialization?

In the beginning there was not much choice, we had to start with the roads. After a while, when almost all roads in Antwerp were done, I started mapping bicycle routes and later on walking routes. The latter is especially interesting, you discover new, small paths, which would otherwise remain unknown. More recently, I am working on railway infrastructures, of course influenced by my job. I have been mapping a lot of different things over the years, but never really spend time on mapping points of interest (POIs).

Why do you map? What motivates you?

Why I map, simply because it's fun! And of course because it fits in my philosophy that FOSS and open data is a step forward. However, if it was not so enjoyable, I would have done something else. It is also rewarding that you discover interesting places, even close to home, places where you have never been and did not know they existed.

Do you do other things related to OpenStreetMap?

In the beginning I participated in a lot of discussions on the mailing lists. I also contributed a lot to the OpenStreetMap wiki to define how objects have to be tagged. Since most topics that interest me, have been sorted out, I became less active. But I still have some hobbyhorses , such as the mapping of paths in Belgium.

What are your ideas about expanding the OpenStreetMap community? How can we motivate more people?

The main question is how you can attract people that have never heard of open data or open source. Most people stop looking for solutions once they encountered Google Maps. They often do not realise that alternatives exist, even those working with Google Map Maker. The only way to reach out to those people, is by increasing the visibility of OpenStreetMap in their world and in the media. Another possibility is to convince sites to use OpenStreetMap instead of Google Maps, but it is almost impossible to fight against a giant with completely integrated services.

What is in your view the greatest strength of OpenStreetMap?

The greatest strength is also one of its greatest weaknesses: the freedom you have while mapping. When you want to put a previously unknown concept on the map, you just create your own tags, and there it is! The problem is that others might have different viewpoints and want to map it in another way. This leads to a lot of discussions.

What are the biggest challenges for OpenStreetMap?

The first challenge is to keep the data up-to-date. As a mapper you need to notice that something changes in a street before you can update it on OpenStreetMap. The possibility to add notes on www.openstreetmap.org is a nice new tool to allow people, who are not into mapping, to point out changes. However, several blind spots where no one takes care of the necessary updates, they do exist. The second challenge, as already hinted in the previous question, is the issue about how we can come to a world-wide consistent way of mapping.

To conclude, is there something else you want to share with the readers?

Looking back at all those years, I feel proud on what we have accomplished with OpenStreetMap. I was lucky to join the project early, and it was fascinating to see the map growing from an empty canvas to what it is now. Who knows where we will be within 10 years?

Argentina Money Advice - is this any good?

Posted by mvexel on 4 November 2014 in English (English)

I am headed to Buenos Aires for SOTM 2014 tomorrow, and reading up on money and general travel tips. I found this page on bringing and exchanging money. Some of the tips in there:

  • Bring cash, preferably in US$50 / US$100 bills
  • Pay in US$ whenever you can.
  • There is an unofficial 'blue dollar' rate that is much better than the official US$ / Peso rate.

I have never been to Argentina before, and I have no idea if these are good tips. Perhaps an Argentinean mapper can shed some light on this?

See you at SOTM!

feel good

Today I mapped a place that I love, I spent some happy days in, and it was almost totally absent from the map !

Talk about feeling good ;-)

What am I doing wrong, re: using the embed feature (its not working)

Posted by DaCor on 3 November 2014 in English (English)

when I copy the html and paste it into a page, I only get a zoom 1 view, not the view I was looking at when I opened the Share sidebar

Surely this should be as simple as copy the code and paste it in

This is not an issue on my side either as I embedded both mapbox & stamen maps to make sure and they work fine

Anyone know the github for this sort of stuff, I'd like to raise an issue

GPS track "eye" effect in trees

Posted by adaviel on 3 November 2014 in English (English)

On a couple of occasions I've noticed what I call an "eye" effect when plotting a GPS track through trees. The first time, I walked back and forth along an east-west trail and when I passed a certain spot the traces opened up, then closed again so they were superimposed, leaving a kind of eye shape in the middle. I thought it might make sense if the trees were particularly dense, but they were not - in fact, there was a small open area over a pond to the south.

Recently I noticed a similar effect in another area, this time on a north-south section of trail. Actually walking the trail, it was quite obvious that the tracks were superimposed and then opened up for a distance then became superimposed again. I made several passes and then plotted the tracks to show the direction of travel - it seems that the position of the tracks depends which way I was going. Again, there was a slightly open area to the north - the main track in along the centre of a wooded area running SE-NW, with two small paths leading north and south. The northerly one is through a less densely wooded area. The trees are deciduous, silver birch or similar, about 80ft tall with few lower branches, spaced on average maybe 15ft apart. It's not a particulary dense wood - not at all dark and you can easily see sky between the tree tops. I tried recording more tracks later in the day, and the next day at a different time. The tracks don't align perfectly between each group, but the eye effect is there on each occasion. These tracks are from a Garmin GLO on my hat (taking Dieterdreist's advice). The earlier one (not shown) was with the builtin GPS in my N810 tablet)

I wondered if anyone else had seen this effect, or knew what caused it. I'm a bit perplexed by the effect of direction of travel - surely I'm not seeing a doppler effect at walking speed, and anyway GPS sets are designed to be used when moving.

Langley Imagery

Posted by pnorman on 3 November 2014 in English (English)

Note: Repost of http://paulnorman.ca/blog/2014/11/langley-imagery/

I just got the recent Langley 2014 imagery from their Open Data program loaded onto my server, and I’m impressed. The new imagery has at least as good spatial accuracy, while having better resolution, colours, and being more recent.

Comparison between old and new imagery

In the next few days, I want to release the new layers.

Unfortunately, while Langley is using the PDDL license, other cities in the region are using custom licenses, meaning I have to enquire with each one individually, taking significant time. If they were all using standard licenses, I would have rebuilt my BC Mosaic layer by now and this post would be about updating it to include new sources.
