Extracting regions from planet.osm ?

Posted by adaviel on 28 July 2015 in English (English)

I've been using Merkaartor on LInux for some years. Usually I import a track, zoom in, then use "download more" to download OSM for that region. But there's a 50,000 item limit, so if I'm not zoomed in far enough, it fails.

Years ago I had read that I could get planet.osm as a default start set, but I never did. Now, when I look, it's huge. Merkaartor can't handle that, at least not with the amount of RAM I have. It can't even handle all of Canada without swapping.

I see that the US is split into states, but all of Canada is one big file. Is there any easy way, preferably command-line on Linux, that would let me split out a region from the Canada OSM - one province, or a smaller area ?

Improving the OSM map - why don't we? [7]

Posted by marczoutendijk on 28 July 2015 in English (English)

How do we deal with multiple values for a key?

We all know this situation: you need to add a telephone number to a node and add the line:
phone=00311198765432
Then you find out that there is a second phone number for that node, but you can't add a second phone= tag because OSM doesn't allow that.
The general question is: how do I tag multiple values for one key?
Let's investigate how mappers have solved that problem sofar. The screenshots all are made with OpenPoiMap.


[1.]
This example is the Eiffel tower in Paris for which four architects worked together, but only one gave his name to the final product!
In the source the names are separated with semicolons:
Stephen Sauvestre;Gustave Eiffel;Maurice Koechlin;Émile Nouguier


[2.] One piece of art created by 5 artists (somewhere in Seattle).
Create a new key with a sequential number attached to it for every member of this group. In this specific case I would have started numbering with artist_number_2 because the first one is already in artist_name. Even better, I would have started with artist_name_1 and used it for Andrew Keating and would have omitted artist_name altogether.


[3.] This example is to show how to map multiple sets of related tags to one node. In this case we have man_made=mast which has attached to it 4 (mobile phone) antennas at different heigth and each working with a different technology.
An underscore could have been used as in the previous example, but there seems to be a tendency to tag situations like this with a key:N notation, where N is running over the natural numbers.


[4.] Here we see a combination of both methods. Adding a number (with underscore) at the end of the key to count them or adding the number after the colon. Again, in the case of the fuel I would have started with fuel:diesel:1 for the Biosolar.

Any different opinions on this subject?

All GPS-tracks in an area?

Posted by geoeki on 28 July 2015 in English (English)

Hi there,

is there somehow a possibility to visualize all GPS-tracks that were gethered for the same area? For example I use JOSM, I define my area of interest and for that specific AoI I want to fetch all available GPS-tracks. Hope that was clear!

Thanks!

Removing phone booths in Belgium

Posted by M!dgard on 28 July 2015 in English (English)

All Belgacom/Proximus telephone booths in Belgium are removed from the streets. With changeset #32926155 those that had operator=Belgacom or Proximus have also been removed from OSM.

The remaining phone booths before their removal. Most of them are near Brussels.

I used the following Overpass query:

/* Find all Belgacom/Proximus phone booths in bbox */
(
  node[amenity=telephone][operator~"[Bb]elgacom|[Pp]roximus"]({{bbox}});
  <;
  >;
);

out meta qt;

This fetched all phone booths and also any ways they are connected to. No relations were matched, which was good. Then, in JOSM, I did the following searches to obtain phone booths that are member of a way:

  • type:way (no phone booths were tagged as ways)
  • amenity=telephone child selected

I removed all tags on those 4 nodes.

Then I searched all remaining amenity=telephones and removed the nodes.

Some stats:

  • There were 320 Belgacom/Proximus phone booths left in OSM in Belgium.
  • 316 had operator=Belgacom, 2 belgacom and 2 Belgacom NV
  • 3 phone booths had covered=yes, 1 had covered=no.

Note that at the time of writing there are still 320 other amenity=telephones left in Belgium. (Exactely the same number as I removed!) They haven't been tagged with operator=Belgacom and should be manually surveyed and removed if necessary.

You are invited to add a note like verified that this phone still exists 2015-07-28 to any phones that you have surveyed, to prevent mappers from armchair-mapping them away. (They shouldn't, but just to be sure.) An operator tag is appreciated as well.

Search for amenity=telephones in Belgium

/* Find all phone booths in Belgium */
area["name:en"="Belgium"]->.belgium;
(
  node(area.belgium)[amenity=telephone];
);

out qt;

Starting up again

Posted by Mapping49er on 26 July 2015 in English (English)

Two things got me back into mapping. One I am thinking of retiring and this will give me a lot more time to do it. And two we recently acquired a puppy dog (A Coton de Tulear) that needs taking for walks so I have been exploring local pathways to use for said walks. In any event I have also been a fairly regular user of an iphone/ipad app called Galileo for quite some time now and I love maps.

I realised that it must be well over a year since I looked at doing any mapping. JOSM is not on my current computer (replaced 18 months ago). I do however have loads of photos, routes and speech commentaries that I have meant to use in doing map updates. Always happens when I am on holiday and I never got time to apply them on my return. Places like Ireland, San Francisco, Athens, Sidney, Queensland and Singapore are obviously all the poorer for not having my map updates applied onto OSM!

So first step was to downloaded JOSM which I did yesterday 25/07/15. Some quick reading on how to use - somehow seems easier this time round and then off on a long walk to gather some data. This is an enjoyable and healthy way to do mapping. I like walking and exploring with a purpose and actually find it very relaxing. However the battery on my iphone ran out half way through so I will need to revisit some of the walk. Not too unhappy about that either! I specifically wanted to correct one of the local footpaths which is incorrectly shown on OSM and unfortunately my battery had run out before I got to the relevant bit.

As a result of the above walk however I did work out how to upload traces in .GPX format to OSM. Been meaning to do that for ages and I have a lot of traces to upload. Additionally when using the photos I took on this walk for a location fix I discovered that it did not match with what JOSM was saying. On reading up it seems that I need a plug in to correct this . It appears to work out the correct offset for you when you position objects on your map to line up with the imagery. I haven't tried it yet.

I then started doing some updates - simple things like house numbering - automatic allocation can't handle infills such as the three houses behind ours which all have the same number but designated A B and C to give them unique addresses. Occurred to me that just getting my local town (pop. 6200) up to scratch is a considerable amount of work. I also did some research on data sources for this exercise such as .gml files from the Land registry (another plug in I believe) and a uk post code map. I failed completely after some hours researching in getting what is said to be freely available post code amps as a layer to use on my maps.

So as a result of all this my list of things to follow up got bigger and bigger - am I looking at taking on an unpaid full time job. :) List is :

• Get offset on Bing maps sorted out.
• Get plug in to handle .gml files available from land registry (INSPIRE index polygon data.)
• Work out how to get more layers such as electoral boundaries , district council boundaries etc.
• Work out how use tags better (a lot of reading) - such as how to represent a house barge (I live on a river)
• Look at a tags for entering statistical information freely available from the Office of national statistics such census date.
• Start looking at writing code to help with some of the above - I have an IT background but promotion has meant not doing any coding for quite some time and I miss it!
• Find out about adding photos to the map
• Find someone (preferably local) who I can chat / work with on this.

No doubt this list will keep getting bigger!

Post-Boxes

Posted by Stuart H 42 on 26 July 2015 in English (English)

Added a few post-boxes recently. Roberts postbox site is excellent for finding postboxes that are not yet mapped. Its unusual to know what you don't know. Learning a bit more about the appropriate tags too.

Then hopefully I'll get back to walking around and adding a few more footpaths. I wonder what other people think the OSM lacks that makes a OS map more useful - and if its something we could add easily. I think the OS will win for walking in the wilds guided only be a map and compass; but OSM should win for towns; and should be as good if GPS guided. Thoughts?
