overpass turbo updates

Posted by tyr_asd on 22 June 2014 in English (English)

In the last weeks a few new features got into overpass turbo. Here is a quick heads-up:

Text Markers in MapCSS

You can now finally use MapCSS to display text markers on the map. This is very useful to show the names of displayed features. The following MapCSS statement adds text markers to each node, way or relation on the map and displays whatever is in the tag name:

  node, way relation {
    text: name;

Or take a look at the following example:

Export to Level0

Overpass turbo can now export data into the Level0 editor. Level0 is a very lightweight low-level textual online OSM editor. It can be very handy for example when inspecting tags of a collection of similar objects (such as when checking the names of all restaurants in town).

Additional Stats

When you hover the data-counter box (which shows you how many elements have been loaded and are displayed), you get presented some additional statistics. Currently, only the lag of the Overpass-API server behind the main OSM db is shown, but there is room for more. Is there something you would like to see there? Let me know!

Wizard as URL-parameter

You can now create links to overpass turbo that use the query wizard to create a query (which is loaded on startup and presentet to the user). An example is Such URLs to overpass turbo are both quite short and at least somewhat human readable.

Fiskardo Walking Trails, Kefalonia

Posted by dud1 on 21 June 2014 in English (English)

For anyone visiting the North of Kefalonia there are now three hiking trails that have recently been developed starting from Fiskardo. There are several map information boards in the town (drawn over Google Satellite Imagery) and a descriptive information leaflet (English/Greek) available locally (but no map). All the routes are “currently” well marked. On a recent visit I walked all three trails: 1) The Lighthouse Trail, 2) The Cypress Trail and 3) The Battery Trail and these now all mapped with route relations. The following link provides a summary map.

I’ve also put on the path that is an alternative route up to the castle at Assos. It skirts the cliffs as the southern end of the fort. It is a bit exposed in places and best avoided if you suffer from vertigo! Assos Castle path

Posted by Pieren on 20 June 2014 in English (English)

It seems the Germans like duplicate tags since the country address is easy to deduce from the country polygon. It could be justified on edge cases like "near the borders" or outside the polygon but not generalized, I don't know how this community has reached such senseless decision- Probably from some data consumers too lazy to use some complex queries in a spatial db.... Sad that the majority of contributors have now to assume this bad idea. I like how this community is sometimes pushing for more standardisation/consistency like for postcode polygons or speed limits but here I cannot follow. By chance, in my country, we have a general consensus to avoid unnecessary duplicates.

Tracing Baiji, Iraq

Posted by Unusual User Name on 19 June 2014 in English (English)

I read in a news item somewhere that the refinery in Baiji had been captured by ISIS. I looked at OSM and the town was only weakly mapped, went to edit and saw that the imagery was fantastic. Awesome tracing bliss!. Then I thought to check my “How did you contribute to Openstreetmap” profile and saw I’d never edited in Iraq before – even better! I came back today, finished some streets in the bottom end of town, went to finish the northern end of town – that’s strange I thought, I don’t remember finishing the north – and discovered someone else had found the little pocket of high res tracing joy as well – they must have seen the same news item! But that’s OK, I don’t mind sharing.

We need a name!

Posted by RobJN on 18 June 2014 in English (English)

A few OSM members interested in historic maps are working on our own version of the New York Public Library "Building Inspector". If you've not yet tried it out, go take a look - it's a great site:

So, the core function they are asking contributors to do is to check (inspect) and fix the rough building outlines produced by the computer script. Our version will be the same but will cover any city and any library we can get good maps for. But we need a name.

Current names suggested are:

  • Historic Map Marker
  • Old Map Marker
  • OHM Buildings
  • Historic Map Inspector
  • Building Surveyor
  • Historic Building Constructor
  • Historic Building Fixer
  • Ghost Mapper
  • Ghost Building Mapper
  • Ghost Brick
  • Ghost Bricks and Mortar
  • Houses and History
  • Historic Map Booth
  • Old Building Kiosk
  • Historic Building Outliner

We're after your thoughts - which name works best? Is there some amazing name we haven't thought of yet?

Someone broke OpenStreetMap again

Posted by Amaroussi on 18 June 2014 in English (English)

It appears London appears flooded at least on the map. I can't see where the problem is: can anyone help please because I am getting too frustrated to do that.

...and if it is caused by a genuine vandal, please deal with them harshly. Thanks.

Some Notes from Analyzing OSM US History Data

Posted by dalek2point3 on 16 June 2014 in English (English)

The Data

Today, I've finally gotten a chance to play with data from the OSM History extract that I created using the parser that I wrote about last time.

This is what the data contains:

  • Every node that contains either an amenity, addr:housenumber or place tag.
  • For each node, I record basic metadata, "name" and gnis* tags
  • Every way that contains either an amenity, highway, building or parking tag.
  • For each node, I also record basic metadata and the following tags:
    • name
    • tiger:cfcc, tiger:county, tiger:reviewed
    • access
    • oneway
    • maxspeed
    • lanes

The resulting flatfiles are large, partly because I'm parsing the "history" data, so I'm including every past version of every node and way, in addition to the most current version. There are about 6.3 million node entries and about 48.7 million way entries. For each of these nodes and ways, I ran them through my point-in-poly program to code the county and the MSA that each way / node lies in.

The next big step was to drop imported data. I really dont care about this -- obviously this includes data from the TIGER import but also many other major edits in the US. Interpret the numbers below as the contribution of OSM editors -- but major national level imports. I've not removed smaller county level imports, because I see them as being relevant to my analyses, but also because they're harder to pin down. So the data includes any way, node with the relevant tag touched by a non-TIGER (and some other importer accounts).

Some Highlights

Way data

How many items do we have for each of the 4 types? * Highway = 15.9 million versions, 7.9 million uniques * Building = 6 million versions, 4.9 uniques * Amenity = 460k versions, 331 uniques * Parking = 52.6k uniques, 66k versions, * All data = 22.3 million versions, 13.1 million uniques


Other notes: * About 5.8 million of the 15.9 million way versions have a tigercfcc / tigercounty tag.

Node data (pending)

You can use for mapping. I've added a new context menu (right click or long press on mobile device) for adding notes. When you come back to home you can use them in JOSM.

Visualizing Notes added to OpenStreetMap through Craigslist

Posted by dalek2point3 on 13 June 2014 in English (English)

One of the most prominent users of OpenStreetMap is Craigslist. Craigslist users often use OpenStreetMap to indicate the location of the house / item they are selling. When they dont find the street they're looking for -- Craigslist users have the option to submit a note to the notes system.

I've found these notes to be useful, quite often containing information about subdivisions that are missing from the map. I wanted to visualize all the notes submitted through this system. Even though Craigslist does not submit notes using a dedicated URL (although I think they should!), they use a peculiar notes system and notes from Craigslist almost always look like this one:

bounds: (38.0118,-121.943 - 37.9966,-121.9013)¬es=yes&bbox=-121.943%2C37.9966%2C-121.9013%2C38.0118 Map is missing data here. Freshwater Court in Pittsburg CA is not showing up

Notice -- how they begin with "bounds". This suggests that using the OSM Notes API to search for the text "bounds" should give a reasonably accurate picture of notes from the CL system.

I wrote a script to use the API to get this data, and parse it into a CSV ready for visualization -- you can check out the code on github and visualized the 2980 notes that I found using Cartodb. Each dot contains a link that will take you to the Notes page where you can read the full text of the comment.

And this is what we get! Click on the image to be taken to the CartoDB page (I cant figure out how to embed IFRAMEs in diary entries). You can even download the raw data here
