Web version - mobile version - how long does it take?

Posted by Francois555 on 2 July 2014 in English (English)

Does anyone have an idea how long it takes to move data from the web version of OSM to mobile version (Maps with me)? I have been updating in several countries lately and I cant wait to see my changes in Maps with me! I has been at least three months since the first edit.

Cheers from Italy! (Im updating Perugia now:-)

OSM roads nodes density

Posted by baditaflorin on 1 July 2014 in English (English)

I made some visualizations of the nodes density of roads in OpenStreetMap

For Romania, there where 379.445 ways that generated over 4.7 milions points that where counted in a grid of over 31000 polygons , with area between 7.43 square kilometers to 8.08 square kilometers

All the images can be downloaded from my Dropbox public folder

This would not be possible to made in old QGIS 2.2, 2,0 it would have taken 10 times more time. Big thanks for all the dev that are mentaining and improving QGIS

Trace from Florida Ave to Eastwood

Posted by gnumen on 30 June 2014 in English (English)

We walked all the way to Eastwood more than once but this time I took my GTA02 with me to trace the path - from Marsden Rd -> Lawson St -> Brush Rd -> Rutledge Rd -> Eastwood. The usual process of downloading/cache the maps using wifi which required SD card ( went without any glitch. The maps were downloaded using the wifi WPA2(AES). In order to overcome the MAC based pass thru for captive portal of Pfsense entered the MAC addr of netgear in the Pass thru MAC table( risk, I know). BUT when ever the gps is enabled, the GTA02 almost within seconds alarms about low battery which wasn't the case previously but this time only difference that I found was that after every reboot I was not made to configure the SD card and the SD card retained the previous gps traces as well as the map cache(s).. Hmmmm should I call it usual or unusual. I took care of the low battery issue with the Sony cycleenergy Power bank. Don't know why it's behaving in such a manner. ##Some random observation(s)/steps taken - In the flight without the SIM card was able to trace without the battery outage alert for quiet sometime. - After reaching Florida ave the device was not able to retain the battery power even for a day. without GSM sim or any other services disabled. - Placed the sim and replaced the SD card once again.

We came back from Eastwood by Public transport system(BUS) - from Eastwood -> HillView Rd -> Terry Rd -> Marsden Rd

New MapRoulette Challenge: Crossing Ways

Posted by mvexel on 30 June 2014 in English (English)

We created a new MapRoulette challenge over at Telenav: Crossing Ways. As always with the Telenav-generated challenges, this one is US only, because we currently only process OpenStreetMap data for the United States. We are working on extending support for other regions.

TL;DR --> On to MapRoulette!!

The Crossing Ways challenge is pretty straightforward and should make for an easy challenge for novice mappers looking for something to fix. It detects ways that cross, but neither way is tagged as a bridge or tunnel. Here is an example:

Example from MapRoulette

If you open this up in iD or JOSM, you will be able to tell the required resolution from the aerial imagery:


In this case, the ways should be connected as there is clearly an intersection. Another possibility is that there actually should be a bridge or tunnel tag on either of the ways.

In this particular case, you can see that there actually is a node at the intersection, but it does not connect both ways. In JOSM, it displays as a 'skinny node':

Skinny node in JOSM.

In this case, you can use JOSM's 'Join' function (shortcut 'J') to connect both ways. In iD, a node connecting two ways will be grey, and a regular node will be white:

Nodes in iD

If you use iD, you can just drag an existing node to the intersection to snap the two ways together, or drag a virtual node to the intersection to create a new intersection node. (Virtual nodes appear between two existing nodes and allow you to quickly create a new node on a way, an example shown below.)

virtual node in iD

There are currently around 19,000 cases in the US alone, so let's get on fixing these annoying bugs in OSM!

On to MapRoulette!

Making a map of the mappers contributing to mapping parties

Posted by Hawkeye on 29 June 2014 in English (English)

Mapping parties are great fun and it's nice to show how much work the people involved put in.

Maybe we should have some type of a map to do this easily? Well, there's some tools out there already see these questions 1 2.

But these solutions don't quite cut it, and we want a nice customised map. So let's use the new date/attic data features in Overpass API. Video explaining them here.

So let's try it, stick this in your web browser:[diff:"2014-06-23T00:00:00Z"];node(55.877838662652906,-4.343075752258301,55.900317043029,-4.297800064086914);out meta;

This gets all the changes made to nodes in that bounding box between 23/06/2014 to the present time. The query returns osm xml file. So just add '.osm' to the end of the file and load this into JOSM or QGIS and were ready to go, right? Nope, the file isn't a standard .osm file. I couldn't get it to load in JOSM or QGIS. So no problem. Let's convert to GeoJSON. Okay, there's a few ways to do this. OGR2OGR is a command line tool and there's a few javascript osm to geojson libraries. Great, now we a rocking. Ah, hang on one sec. I found it difficult to make these tools retain the 'meta' data - e.g. the userID and name of the user who last modified the feature. And we want the meta data so we can credit people who have made the edits not just show where the edits were made.

I found this tool was easy to download and gave the option for meta data:

Install this at command line:

$ npm install -g osmtogeojson

and try something like:

$ osmtogeojson Anniesland.osm > Anniesland.geojson --flatProperties

Brilliant. We can now stick the .geojson in QGIS or Tilemill and make a map:


...looks like overpass api can be used for some nifty stuff, maybe animated snapshots by hour or days....go play.

Save the date - 25th July - ‪#‎MapLesotho‬ mapathon

Posted by DaCor on 29 June 2014 in English (English)

I've been working with some of the guys in Fingal County Council over the last few months on getting OSM going in Lesotho in Africa.

As part of this we are organising a ‪#‎MapLesotho‬ mapathon


25th July 2014


A Mapathon is a coordinated OpenStreetMap indoor mapping event run in various places at the same time.


In conjunction with Action Ireland Trust, a number of Irish OSM members from Fingal County Council traveled to Lesotho for a number of weeks in early 2014 to assist and train regional planners in utilising OSM data.

Another group are planning to travel in early 2015 with the following objectives as part of their visit:

  • Create an OSM community in Lesotho by engaging with local communities and providing training and guidance on surveying and updating OSM
  • Create a basemap of the country for use by all
  • Create an evidence base for decision makers


There will be 2 main tasks created, the first, to map all the buildings, roads, major features etc within larger urban areas. The second task will involve identifying rural settlements and the main routes in and out of those settlements and any major features nearby e.g. rivers.


This mapathon is being organised by Irish OSM members in conjunction with Lesotho members.

We want to have as many people as possible attending the mapathon on 25th July.......many hands make light work.

There are mapathons planned in Lesotho, Ireland, Germany and elsewhere all on the same date so come be part of a truly collaborative effort

Spread The Word

If you are letting people know about the event, use hashtag #MapLesotho and shortlink

The Art of Maps

Posted by Tuan Ifan Vpy on 29 June 2014 in English (English)

Map is an Art. I didn't know that until I finished mapping all details in Zone A, Phú Mỹ Hưng New City Area, in the Saigon South New Urban area of Ho Chi Minh City.

What fascinates me was the colourful rendering of various areas and items, such as residential zones, schools, rivers and parks. Well, after slow mapping for 2 years and intensive work for 3 days by everyone and me, it turns out to be a piece of art.

Btw, I also draw administrative boundaries to the subdivisions of the Zone A - Phu My Hung. This sounds weird because they are NOT administrative, but they do help proper addresses to render. Further, zone boundaries make it more convenient for users when searching for them in the search box.

Now I know that OPENmapping is not about drawing roads. It brings everything.

JetBlue Inflight Maps is using OpenStreetMap!

Posted by dalek2point3 on 28 June 2014 in English (English)

On my recent trip to San Diego, I casually started looking at the flight tracker on the JetBlue in-flight entertainment system, and lo-and-behold they were using OSM! And with nice attribution too!

The pictures I got were a little grainy, but the attribution is nicely visible!


Welcome Iceland: streetlist and housenumber evaluations for whole Iceland

Posted by okilimu on 28 June 2014 in English (English)

Streetlist and housenumber evaluations for whole Iceland

On SOTM-EU in Karlsruhe a few weeks ago, a german OSM-Mapper asked for housenumber evaluations about Iceland.

I asked a heavy active OSM mapper in Reykjavik (OSM name: Kjarrval), if he could find out, if a countrywide streetlist or housenumber list would be available from iceland government.

Data Source

After a very short time, he was able to give a positive answer: the Statistics Iceland Government offers a countrywide housenumber list with a relative open license. A little bad news: the license is open enough for the evaluation of osm data, but the housenumbers (including geocoodinates) can't be imported directly.

Missing administrative boundaries, artifical calculated

Unfortunately, the administrative boundaries for the iceland municpalities are very incomplete in OSM. They would be available for import, but up to now, they aren't.

I decided to use the housenumber list above, which have geocoordinates for every address, to calculate artifical admin boundaries, because i need boundaries for my evaluations. On the SOTM-EU, i provided a brief overview for this method in my presentation slides, downable at SOTM-EU Page on the lecture. At the bottom, download 'Presentation slides' and look at Extension 2, starting at page 28.

The calculated boundaries will not be imported into OSM, of course, they will just be imported in my evaluation database, where i usually store a copy of the boundaries from OSM database.

Streetlist evaluation for Iceland

I finished the coding for import at 28.06. and was able to make a first evaluation. The structured view of the municipalities can be viewed at or have a look at the graphical overview.

The first evaluation showed, that the most relative official streets in OSM are in

  1. Hafnarfjarðarkaupstaður (86%) with 280 of 323 streets,

  2. Reykjavíkurborg (83%) with 911 of 1088 streets,

  3. Akraneskaupstaður (82%) with 87 of 106 streets,

and unfortunately with 7 muncipalities, which have not one named street from the official streetlist.

Housenumber evaluation for Iceland

The first evaluation was calculated at 27.06. and i posted the first result for every municipality in the german OSM Forum.

The best 4 municipalities with most relative addresses are:

  1. Seltjarnarnesbær (86%) with 845 of 975 addresses,

  2. Sveitarfélagið Ölfus (79%) with 552 of 698 addresses,

  3. Hafnarfjarðarkaupstaður (77%) with 4220 of 5460 addresses,

  4. Reykjavíkurborg (77%) with 16184 of 20838 addresses.

The table oriented evaluations are available (scroll down to Ísland), for the graphical overview first go the table oriented evaluation of the muncipality and click on the result page at the very top at 'grafische Anzeige'. Sorry for this indirect link, i work on a better integration into the graphical overview at. For example, have a look at Reykjavíkurborg.

Open Issues for Iceland evaluations

Up to now, i have only made one single test for correct sorting of the iceland special characters. I work on it.

The most important issue is to support english language to the housenumber evaluation. I will start on this issue next and hope to have a first version in two weeks from now on.

An alternative to /export

Posted by Zverik on 28 June 2014 in English (English)

Have you ever printed a map? Clicked a hundred times on "Export" button on Installed mapnik or maperitive and spent days configuring a database and customizing a style? Did you wish for a simple web service that lets you select a bounding box and produces a hi-dpi raster or vector image? Well, there is one now. It is called Get Veloroad, for a style it was created for.

On the side panel you choose paper format and margins, add a GPX trace if needed, select style ("veloroad" and "" are available), image format, and press "Submit". If the server is not overloaded, you'll get your image in a minute, in glorious 300 dpi. SVG files are postprocessed, so you can easily move labels as a whole, instead of separate letters (the most annoying trait of mapnik-generated maps).

Alas, my server cannot fit all the planet, so there are only Baltic countries and parts of Russia and Finland. Everything is open-sourced though, so I hope soon we'll see a worldwide service for producing high-resolution images.

Data that I capture with my phone

Unfortunately it's not possible to drive the car and at the same time take notes about streets and places, for example, but it's possible to capture data that can be useful in several projects.

OSM Node Density 2014

Posted by tyr_asd on 27 June 2014 in English (English)

Exactly one year ago I published my first visualization of the global OpenStreetMap data density. This is the updated 2014 edition.

(click image for slippy map or here for high-res images)

Each pixel shows the number of nodes in its corresponding area¹. But this year every point that has data in it is shown (i.e. there is at least one node at that location - last year only locations with more than 1000 nodes were included). Also, the slippy map has two more zoom levels which reveal even more impressive details like on this crop of the central Alps:

Here is a low-zoom image of the whole planet:

¹ Yes, this is Mercator map tile area, not actual on-the-ground area. Keep this in mind when comparing regions at different latitudes!

² Copying: visualizations © Martin Raifer, CC-BY - source data © OpenStreetMap contributors, ODbL

PS: The visualizations are based on a planet file I downloaded one or two weeks ago. It was processed using some custom scripts based on node-osmium, the graphics were made with gnuplot (just like last years') and finally the map tiles for the slippy map were cut using imagemagick. I could probably explain the individual steps in a separate blog post, if anyone was interested - let me know!

Current Activity List

Posted by Govanus on 25 June 2014 in English (English)

this is not exsusitive but outlines my work program for OSM:-

Finish adding CAB offical tags for OxCAB Finish suport services missing from OSM needed for CAB mapping such as third-party support and advice services. Add The Regional CAB sites following toward the rest of the organisation...

Compleat the records and relations to all the garages operated by the council in Oxford. as well as neighbouring others.

finish multilayer buildings for buildings at southfiled park and progressing futher out accross the city as suveying is done.[I've had more in notes for a ling time now]

Learn 3dPhoto-survaying to increase accuracy of Southfiled Park features.

Try to develop a decently accurate hight aware suvey technique to add public relm and communial lamps and secuity features across oxford [I done some preservey exploration to the centre of oxford and at southfiled park, hght will be important for the referance number to make sence as a lot are mount high on the side of buildings to avoid haveing poles]

Compleate the NPLG records gathered from lable surveys.[both Oxford City and the Vale of the White horse councils add them in codes on their bins....

compleate the transfer manually of refrances and route codes about railways from official sources like the NESA and line rental matieral [theis is helpful for users of live datafeeds and planning - there also is the issue of details of posaic nameing that passengers use but are different than the rail industry internaly] - Ialso have mapped these three different ways in the past some with some without the use of relations.

Need to review rail tagging especially when addingg the tracks/roads for each line to avoid logical errors being introduced.

Look at trying to expand highway areas [ I note some recetly became deleted and in the past people have not felt happy with how the tags define them [I was originaly working on the proposed standard but others seem to want to cover things differently so the standard went into dispute. the features I hope to work to add will be geting into the sub 1metre locational sensitivity level [wether I can get the coords absolutely accurate {using all technical meanings here} or to some relative approximation {more technical meanings used}] At this level road widths and edge shapes look very significant.

Look at fixing any errors and omisions to Wash Common [see previous work for location]

Look to chip in to work going on in Newbury as well as finaly getting multilevel models translated from pdf to OSM of the new centre of town developments and correting big interpretaion mistakes to the other shopping centres.

Do more work in andover and bradford.

work in Northumbria

fix problems in my previous work that I failed to get good location inputs for mainly from paralax, vegitaion cover, poor resurlution and lighting, and no clear fix points for base picture misalignments . What I fail on posstional accuracy I have hoped to makeup thematicly and with a sence relative layout sence.

Construction sites and other new changes needed.

improving detail like addeding relvent referances, addresses and surfaces etc.

add referance numbers for offical rights of way.

Add 3d data when understood and availble.

map out the parking restictions in oxford and Newbury. including on developing the clausual deffinitions.

develop bosme

various activities overseas

look at adding NUTS and LAU to Europe.

add offical language translations to various sites [such as russion arabic and chinese forms]

add more thangs I notice are missing....

Well thats a lot to work on for a while. So if it looks like I scattering about and leaving nothing finished then its probably competeing for time with these ares with equal urgancies.


edit expanded notes

Posted by Govanus on 25 June 2014 in English (English)

Assorted modifications in Oxford addition at Hilltop rd. Still needs work but to much treeand shadow on bing today.. Addtion of the 2014 urban beach hope it shows up more this time. And the current changes starting today in Brasenose lane including cycle P suspensions
