OsmHydrant

Posted by robert|koch on 24 April 2014 in English (English)

Hi all,

if you want to map hydrants, there is a new - easy to use - OpenStreetMap editor online: OsmHydrant

OsmHydrant offers the following features to mappers or those who are new to OSM:

  • mobile ready editor (works on current smartphones and tablets)
  • add/change/move/delete hydrants
  • no knowledge about OSM-tags required
  • beautiful rendering of hydrants
  • multi-lingual interface in 4 languages: DE, EN, PL & UK

In the near future I want to implement the following features:

  • support for suction_place tags and water_reservoir
  • unit calculator, e.g.: l/min -> m³/h

Brave Mappers of Wherever You Are

Posted by mvexel on 23 April 2014 in English (English)

From time to time someone will ask me: 'How do I find out who my fellow local mappers are?'

That can be a surprisingly hard question to answer. You can go to your user page and see a few people who have indicated their 'home location' to be near yours. OSM user page map That does not work so well for a variety of reasons:

  1. Not all people set their home locations. My guess is most people don't.
  2. People don't update their home locations when they move.
  3. The home location is not necessarily where that person is mapping.

You can also have a look at Pascal Neis's wonderful 'Overview of OpenStreetMap Contributors aka Who's around me?' map, which gives you a visual impression of mappers in your area based on actual mapping activity. Pascal's page in action This is much better! But it still does not always give you the complete picture. For example, if I navigate to Salt Lake City, where I have lived and mapped for three years now, I can't find myself on that map. I guess I am mapping too much in other places for Pascal's algorithm to detect me as a local mapper.

Dennis Zielstra's engaging talk 'Where Are The US Mappers At' at State Of The Map US 2014 made me revisit this problem (and dig up some old code, more on that in a bit). He presented an in-depth analysis on user engagement and community activity for top US cities. Following that talk, I had a few interesting discussions focusing on questions like

What to do about those cities that do not have an active local community?

How can we make it easier for people to start organizing their community locally?

If we're going to address these questions, we need a better way to identify who active mappers in our area are, and contact them.

For contacting, we will need the groups functionality on OSM.org that has been under development for a while. Being at SOTM US and catching up with lots of mappers from all over made me eager to get this project going again.

For identifying, I think I can contribute something. I wrote some code on top of osmjs a couple of years ago that I dusted off. It processes a full history planet file for an area and outputs stats for all users who have ever contributed in that area, things like:

  • First and last edit
  • Total number of edits
  • Number of edits still visible in today's data

I ran it on Los Angeles county and this is what came out. As a list, it is already pretty insightful, but you can roll nice visualizations with it as well. Enter the Brave Mappers Of Wherever You Are project that was sitting under the same layer of dust. I ran it on the LA county output with this result.

Brave Mappers of LA County

Brave Mappers shows a timeline of mappers for your area based on historical OSM data. A long bar is a mapper who has been active for a long time, like techlady here:

techlady

The users are sorted by how long they have been active in this area. Scrolling down, there are some interesting outliers to be seen. Here is DaveHansenTiger, the original TIGER import account:

DaveHansenTiger

As expected, active for a short time right at the beginning of the timeline. The green color of their bar means that they mostly created things (rather than modifying or deleting). The transparency indicates most of their work is no longer in the current data. In this case that is probably a good thing!

Finally, clicking on a user's bar gives some more details on their contributions:

chart

If you want a Brave Mappers page (or just the spreadsheet) for your area, that can be arranged! If you feel up to it, you can clone the OSMQualityMetrics repo and run UserStats.js yourself on a full history planet for your area, then process it with the script in the bravemappers repo. Or you can send me an OSM POLY file and I will try and make some time to do it for you!

2014 Spring #editathon: Come Out and Map in 10 US Cities or from Home

Posted by lxbarth on 23 April 2014 in English (English)

This weekend, the quarterly US #editathon takes place in 10 US cities - read all about it on the OpenStreetMap US blog.

The #editathons are not just a great excuse to meet up with other OpenStreetMappers to push on projects, but also an opportunity to learn more about OpenStreetMap. In DC we'll be hosting the #editathon in the Mapbox garage. It's going to be great weather so expect some people to go outside and survey too. Read up on the Mapbox blog on how to find the Mapbox garage. Here's a photo from last year's event there:

"Korrekte" Ampelpositionen

Posted by MKnight on 22 April 2014 in German (Deutsch)

Schon seit geraumer Zeit stört es mich diffus, dass wir zwar ein red_turn:right haben, es aber so gut wie nie eingesetzt wird, da Ampeln in aller Regel direkt auf den Kreuzungsknoten gepackt werden. Taginfo meint, dass das 11 Mal (Edit: in .de 8 Mal von 5000) verwendet werden würde oO.

Die bessere Lösung wäre m.E., wenn man Grünpfeile mit einer Relation ähnlich wie bei Abbiegerestriktionen handhaben würde, Hammwer nich, also endlich mal Ärmel hochgekrempelt, und natürlich gleich eine etwas kompliziertere Kreuzung aufgedröselt:

Kreuzung

Selbstverständlich dürfen da Abbiegerestriktionen, turn:lanes etc. nicht fehlen, hab ich jetzt ne Stunde gebraucht 5 Ampeln zu malen. Beim nächsten Mal überlege ich mir das zweimal ;)

Ergebnis: https://www.openstreetmap.org/#map=19/50.99090/11.32176

John Muir Way - a start of a good relation

Posted by Hawkeye on 22 April 2014 in English (English)

Can't help thinking John Muir, the eminent 19th Century (Scottish-American) naturalist would have been a huge fan of OpenStreetMap. He was a bit of a hacker/maker in his day and his love of a good wander (up to a 1000 miles or more) would have made him a handy mapper.

John Muir

Anyway, the John Muir Way has recently been officially opened for hiking and cycling across the central belt of Scotland. It a coast to coast route (with slightly different routes if you are cycling or on foot).

There's still a little bit of work required on mapping the hiking route. But the bicycle route is one continuous section. You can view the route and get some analysis of it here. What a neat tool that is, Kudos to GrundID.

But how do you work out how many people have contributed to mapping this? All the ways, nodes etc?

Well, I couldn't find a service that did this for me. But I knew it's pretty easy, so I used osmar package for R. Although, it doesn't look through the whole history of all the ways making up the relation/route it's a pretty good estimate. You can download R easily and I recommend Rstudio as a nice interface but plain R is all you really need.

Here's the code.

But if you can't wait the answer is approx 106 people have helped to edit the ways and nodes that make up the route.

If anyone can recommend other tools etc for relations and route analysis - please do. Thanks

scrolling the map in JSOM on MacOS

Posted by Dion Dock on 22 April 2014 in English (English)

I've given up on JSOM for maybe a year ever since Option+Click+hold quit dragging/scrolling the map. While I've seen a lot of suggestions on how to get this working again, it appears the best solution is hardware: get a two button mouse and Right Click+hold to scroll.

rececent change to parking tags

Posted by Govanus on 22 April 2014 in English (English)

revising mainly parking restictions. mentor prevously updateed the tags to parking lane routes but this along with illegal parking problems is likely to confuse, so removed it all to lok at more appropriate parking lableing. If parking at the side of a garage road you create a blockage problem either for turning vehicals on one side or blocking a garage door on the other. were garages face each other both sides block doors. The police have already athorised garage owners that they can leagaly tow or dispose of vihicals in front of the doors without any warning. The areas are laid to allow 24hr access for large vehicals to the garages. if now used in a storage mode then it is only a loading stop that can be made and you need to be ready to move out of the way. vandalisum and rouge parking has dammaged some low walls and signs and illegal parking followed. originaly parking on the main road on the estate was also banned but recently this began to be increasingly ignored by residents not wanting to pay for garages so now a large parking scheme has been introduced but not on the garage lands as they are private and not adopted highways. I'll need to rethink the original tagging as I suspect the original is likely to be mass retagged again without local knowledge if I just revet it back to private like a houses drive

Cycle-mapping in West Lothian

Posted by Hobgoblin on 21 April 2014 in English (English)

The sun eventually came out this afternoon, so I decided to cycle to Armadale and add a few new streets to the map. I had a printout of the ISO OSM Analysis map which showed seven streets that were on the Ordnance Survey's map but not on OSM. There was a strong cool breeze blowing from the East which gave me a nice easy ride from Livingston.
I arrived at the railway station in Armadale which had not been mapped completely, and since it was practically deserted, I spent a few minutes cycling along every aisle in the car park to get a record on my GPS. Then on to the new housing estate nearby. I managed to find all seven streets to match the missing ones but I think I may have to return once the builders have finished as there are some more new streets still under construction and not enough signs to tell you which street is which. The cycle back home was a struggle since I was now heading into the wind, However, I had gathered a lot of useful data which should help to move West Lothian up from 98.59% completeness figure.
