Re: [osmosis-dev] Problems importing osm files to API bd
2011/2/18 Brett Henderson br...@bretth.com
Hi Egoitz,
Apologies for the slow reply, but better late than never :-)
Yes much better XD
Using Ecuador osm file form Cloudmade at Feb 8, 2011 :
SEVERE: Thread for task 1-read-xml-0.6 failed
org.openstreetmap.osmosis.core.OsmosisRuntimeException: Unable to insert
user with id 222199 into the database.
Caused by: org.postgresql.util.PSQLException: ERROR: duplicate key value
violates unique constraint users_display_name_idx
I haven't seen this before, but I suspect I know what is causing it. I'm
guessing that there are two entities (nodes, ways or relations) that have
different user ids but the same display name in the file. I haven't seen it
before, but it's possible that a user has been renamed, then subsequently a
separate user renamed to user the same name as the first user's original
name. That might cause the same username to appear with different user ids.
If you download a fresh planet all usernames will be aligned, and if you
subsequently load that planet into a database and keep the database
up-to-date with daily/hourly/minutely diffs the users will also be kept
correctly named because users are stored in a separate users table
eliminating duplication. It's only a problem when applying diffs to XML
files because only updated entities will have their usernames updated, any
existing entities will continue to have the names from the input XML file.
Thanks I'll extract Ecuador .osm file directly from the latest planet file.
Using the osm file result of the extract sentence I've writed earlier :
SEVERE: Thread for task 1-read-xml-0.6 failed
org.openstreetmap.osmosis.core.OsmosisRuntimeException: Unable to load
current way nodes.
Caused by: org.postgresql.util.PSQLException: ERROR: insert or update on
table current_way_nodes violates foreign key constraint
current_way_nodes_node_id_fkey
Detail: Key (node_id)=(490767853) is not present in table current_nodes
These are usually caused by inconsistencies in the XML file you've
downloaded. In both cases ways are referring to nodes that don't exist in
the file. Without knowing the complete history of the files you've
downloaded it's hard to know why this might be.
In the past, I've simply dropped the current_way_nodes_node_id_fkey
constraint to make it work, but that could potentially cause other issues.
Using Spain osm file from Cloudmade at Feb 8, 2011 :
All ok. I can use JOSM to access ( and even change ) the data from the API
DB.
The API BD is always new ( dropdb : createdb : rake db:migrate : rake test
) before the population senteces.
Lets use an example to explain the problem :
Using a osm file downloaded from Cloudmade that works correctly ( importing
to APIDB and editing with JOSM ), if I extract a bounding box with this
sentence ... :
bzcat spain.osm.bz2 | osmosis --read-xml file=/dev/stdin
enableDateParsing=no --bounding-box top=43.5 left=-3.5 bottom=42.0
right=-1.0 --write-xml file=- | bzip2 extracted.osm.bz2
and try to populate de APIDB with the extracted file ... :
bzcat extracted.osm.bz2 | osmosis --read-xml-0.6 file=- populateCurrent=yes
host=localhost database=xxx user=xxx paasword=xxx
validateSchemaVersion=no
Ends with error, ( Detail: Key (node_id)=(490767853) is not present in table
current_nodes ) that node is out of the extract bounding box and it
thosen't appear at extracted.osm.bz2 but it appears at spain.osm.bz2 ( the
node is part of a way that starts at the bounding box but ends outside the
bounding box ).
So tried the drop constraint solution :
psql -d openstreetmap -c ALTER TABLE current_way_nodes DROP CONSTRAINT
current_way_node_id_fkey CASCADE;
It solved the populating problems ( no errors ), but using JOSM to see the
APIBD information causes error if I try to view any way related with the
ways that created the previous importing error ( it works if I view a zone
with no ways related with the outside of the bounding box ):

Re: [OSM-dev] Different styles for each country/region
Hi, (sorry, resent to list with correct from) thanks for your answer. It was already quite enlightening, because I had no idea of the technical problems. But, I'm not yet 100% satisfied :) I'll see that I can do about the remaining issues. People desperately trying to change their countries look and feel to what they are used to from the only road atlas they ever owned might be tempted to fix the style without the necessary skills and might very well create ugly styles ruining the nice user experience we have now. Well, but the system could set up some barrier, so that not everyone could just change the style: - only people with a certain amount of edits would have the right to change the style - votes are necessary to change the style - or something like that Unfortunatly beeing an avid mapper doesn't mean that you know about renderers, stylesheets or have any sense of style and design whatsoever. And the completly broken tag proposal and voting process shows that openstreetmap is not a democracy. Also, creating this style of map would only be necessary once or twice. I think, most west european countries are already at some point where the important stuff is already inclued in OSM - it would then not be a problem to design a nice template for their country. Of course, people may tend to copy the style of their printed road atlasses or of Google Maps or whatever; still, some styles are not specific to one publisher. Think of the Autobahn signs in Germany, for example. Copying the style of printed road atlases, Google Maps or other copyrighted works might very well leave openstreetmap open to legal liabilities. This is certainly not a problem for blue Autobahn signs, might get tricky if you want to use the logos of subway operators and it gets outright illegal if you want to copy the look and feel of Google Maps. 1.) 200 copies of the style with small tweaks to render the correct language of the name tags and the correct highway colors eats more RAM then any reasonable box has to spare on that (IIRC the amount is in the two digit gigabyte range.) I don't know about the interna of the rendering, but is this really such a big issue? I always thought that the rendering process is idle most of the time and only comes to work when somebody made a change. Well, but I don't know about that :) Yes it is. The main tile server is pushing 50 Megabytes per Second of tiles, most of them freshly rendered. The tiles@home project prerenderes every change and need about two hours till a change makes it to the rendered tiles and needs about 6 weeks to rerender the world. The world is _large_ and the rate of change in openstreetmap is substantial. 3.) Some people (say Germans) will expect all of the world rendered in the style they are used to (lets call it the german style), other Germans would expect Germany in the german style and France in the french rendering style. How do you resolve that? How do you deal with the fact that some tiles are half french and half german? Well? How do you? 4.) How do you allow people to select map style? On of the earliest problems of the toolserver map display was that a dropdown list with 200 language layers in Openlayers is bulky at best and breaks old browsers at worst. But that can't really be a problem, right? The choice can be narrowed down really nicely: Oh, it is a very real problem. 1. Check the browsers language 2. Check, which area is currently viewed. If then a German user (= German browser) looks at a place in Germany, it would just display one option: German (native). If one looked at Austria, it would change the list and display: German style and Austrian style. If a British user looks at Germany, it would show: British style with English names, British style with German names, German native style. Imho, this would reasonably satisfy all needs. German user looking at a Chinese city: German style with German names, German style with Chinese names, Chinese native style, Chinese native style + reading (the last one would only be necessary in areas such as China, Japan or Taiwan, where it is impossible/difficult for people having a slight knowledge of the language to be able to read _every_ geographical name.) I guess, it is not necessary to offer a German user the option to display a Chinese city with Arabian names. Perhaps not that. But what if I zoom out until I see three european countries with five languages? What if I want to show that map to a Japanese collegue? What if I want to show a map of Austria to a British collegue. Do I want German style, Austrian style or British style? With German or English names? All of that are _solvable_ problem. But very real problem and we the lack the man power to solve them at the moment. If the system changed the dropdown list according to the viewed region, it would significantly narrow the options. And, if the user then wants to have China displayed with

[OSM-dev] Some Questions about the Collaboration of OpenStreetMap and Wikipedia
Hi developers, I'm student who is currently working on using OpenStreetMap to facilitate our project. Now I want to retrieve Wikipedia entry from OpenStreetMap to fertilize the data source for our project. To do this, I crawled OSM data, and found there are few wikipedia tags in my test region (Singapore downtown: minLon=103.84051, maxLon=103.86137, minLat=1.28026, maxLat=1.29298). On the other hand, there are plentiful wikipedia entries in the same area on Google Map. Hence, I guess that the wikipedia entry on OpenStreetMap is added manually. Am I correct? Also, I'm eager to know whether there is any automatic wikipedia entry recognition tool for OpenStreetMap, in case I'm not aware of them. I've also read some articles that introduce the collaboration of OpenStreetMap and Wikipedia, such as http://wiki.openstreetmap.org/wiki/Collaboration_with_Wikipediagoog_546150628 , http://meta.wikimedia.org/wiki/OpenStreetMap. One interesting thing is that I found there is a mirror OpenStreetMap: http://toolserver.org/~kolossos/openlayers/kml-on-ol.php?la=enuselang=enlon=103.853039lat=1.28625rang=50map=1. And I found there are far more wikipedia entries than those on the main site in my test region, though entry size is still smaller than that on Google Map. So, does this mirror site use some additional techniques to discover wikipedia entries? or is the data source of the mirror site is a bit different from that of the main site?

It is generally sufficient to add 1 wikipedia-tag for one language, as all the others can be fetched from the interlanguage links Wikipedia is offering. Only in rare cases there might be need for additional tags for different languages (in cases where the wikipedia structure for different languages is differing, e.g. some languages have a specific article, in other languages the same feature is described inside the article of another thing). cheers, Martin PS: This would also make a beautiful project of the month...

[osmosis-dev] [PATCH] Make --used-node keep nodes used in relations as well
Hi list
The --used-node task keeps only the nodes that are used by at least one
way. This allows unnecessary nodes to be thrown out while ensuring ways
remain complete. *Relations*, however, are broken as the nodes
referenced by these are thrown out.
The attached trivial patch extends --used-node to keep a node if it is
referenced by at least one way *or relation* in the input stream. I am
using this locally and it works for me like a charm.

The problem is that many entities have the corresponding wikipedia entries, but the wikipedia tags haven't been added in the OSM data. Hence only relying on wikipedia tags may overlook much potential knowledge. Yes, I agree the coordinates cannot be directly imported into OSM, otherwise, some inconsistence issues may occur. Today I was looking at some places (countries, states and cities) and found that despite some wikipedia links most of them are actually missing. I invite everybody to look in his region for features (not only place-features) to see, if they are already linked to wikipedia. In case they are not I suggest to add a tag in the form: wikipedia=language-code:article-name as suggested here: http://wiki.openstreetmap.org/wiki/Key:wikipedia e.g. wikipedia=en:London or wikipedia=it:Hong_Kong (copy the value from the URL to avoid typos). It is generally sufficient to add 1 wikipedia-tag for one language, as all the others can be fetched from the interlanguage links Wikipedia is offering. Only in rare cases there might be need for additional tags for different languages (in cases where the wikipedia structure for different languages is differing, e.g. some languages have a specific article, in other languages the same feature is described inside the article of another thing). In addition to manual editing by contributors, I'm also thinking about creating wikipedia tags or retrieving wikipedia entries automatically by analyzing the information from the current OSM data. cheers, Martin PS: This would also make a beautiful project of the month...

Re: [josm-dev] Proj4J - New plugin supporting 3000+ projections
Perhaps my sensationalist subject line turned people off from this. Any chance this could get added to the svn? I'd like to submit patches against that rather than continually updating the zip on the ticket. I'd do so myself, but I don't want to be presumptuous and ask for an svn account.

Hello Josh, I think it's OK if you do it yourself. Since it's a new plugin it won't hurt anyone if it's committed to SVN. Put it next to hte other plugins. Plugins are in the normal OSM SVN, not in JOSM SVN. It's easy to get an SVN account for the OSM SVN.
