Where we are now on getting OpenStreetMap into Wikipedia and what we need to do
by Ævar Arnfjörð Bjarmason 11 Sep '09

11 Sep '09

Hello there. This is a quick status update on the project to get OpenStreetMap maps into Wikipedia and on the Wikimedia/OpenStreetMap toolserver setup. For those that don't know what it's all about we're: * Setting up a testing platform (ptolemy & ortelius) to serve OSM maps in Wikipedia which can be rolled into production * Setting up a toolserver (cassini) which interested parties can use to write tools that use OSM data. And combine it with Wikimedia data if they want. Here's an (outdated!) wiki page with some more info: http://meta.wikimedia.org/wiki/OpenStreetMap And here's a recent talk I gave at Wikimania discussing the current status: http://wikimania2009.wikimedia.org/wiki/Proceedings:143 Until now we only had 1/3 machines active & accessible due to various combinations of waiting for hardware, people being busy and it being unclear who actually got access to those machines that I won't go into. That one machine was the nascent WMOSM Toolserver Cassini. I set up a prototype multilingular rendering (since ptolemy and ortelius weren't available at the time) which you can see here: http://cassini.toolserver.org/tile-browse/ What we need to to currently is: * Admins to set up ptolemy / ortelius so that they replicate the DB / mirror tiles * Get interested users/developers to *use* cassini for their tools so we can get neat stuff like the multilingular-country-list (http://cassini.toolserver.org/~mazder/multilingual-country-list/). Sign up here: https://wiki.toolserver.org/view/Account_request * Cassini also needs some admin love * Work on this buglist (and more bugs) to get OSM into Wikipedia: http://tinyurl.com/nv2sap I did most of this on Cassini (see setup notes: http://tinyurl.com/mbblj3) but I have limited time on it (especially until Christmas) and system administration isn't my strong suit. So unless we get other people to help this project is going to go *slooowly* and you won't have OSM on Wikipedia until 2010. Before WM2009 we had the unfortunate problem of interested parties needing to do the above not getting access due to the issues above. However the machines are up *now* and during WM2009 uncertainties about who could grant access were finally solved (brion will be dictator). So, any potential admins for ptolemy and ortelius will have to: 1. Be qualified & motivated Preferably someone who's worked with the OSM toolchain or is willing to learn. If you're maintaining your own ad-hoc rendering somewhere and are running out of server space you'll probably be motivated to get this working sooner. 2. Reveal their name & address to the Wikimedia foundation That's a requirement Wikimedia requires of all server administrators. 3. Agree to Wikimedia's privacy policy URL: http://wikimediafoundation.org/wiki/Privacy_policy ptolemy and ortelius are otherwise distinct servers on the Wikimedia network so this amounts to basically not being silly and running a Quake III server on them, or nmap-ing the Internet. Cassini is more sensitive and harder to gain access to since root admins on Cassini have access to private data about Wikimedia users (e.g. raw database access, login cookies and so on). But in both cases we should be able to give elevated non-Unix-root privileges. All of this pending approval by Wikimedia of course.

TomTom Launches Open Source Navigation Project
by Daniel Kinzler 11 Sep '09

11 Sep '09

HI all I just stubeled uppon an annoucement [1] that TomTom (make of GPS navigation devices) will launch an OSS project for location aware services/data, called OpenLR [2]. They call it a "universal location referencing technology" and call it "map-agnostic". Not quite sure what's behind it - a collection of data layer? an protocol for supplying and polling such data? I didn't dig deep, just though it might interest you... -- daniel [1] http://ostatic.com/blog/tomtom-launches-open-source-navigation-project [2] http://www.tomtom.com/page/openLR -- Daniel Kinzler Software Developer Wikimedia Deutschland Phone +49 30 219 158 260 Imagine a world in which every single human being can freely share in the sum of all knowledge.

Maps interface to the users
by Marcin Cieslak 11 Sep '09

11 Sep '09

Hello, On a side of the extension discussion I asked myself a question: How should plain editors use the new maps? I can imagine the following simple things that most people would probably want to do first: 1. just put a static map in the article 2. overlay the static map with some simple layer of images (like it's done with templates using CSS) How should they do (1)? Our current extensions provide usually some tag with coordinates as parameters. Do you think it would be feasible that we could allow use of OSM URLs, so that the user can just go to OSM, pan and zoom as they wish, pick a permalink or shortlink and paste it into some MediaWiki tag? Any thoughts on solving (2) better? I thinking about something simpler than what we have now (since we should be able to provide custom layers anyway at some point). -- << Marcin Cieslak // saper(a)saper.info >>

Usage of Maps instead of SlippyMap
by jeroen De Dauw 07 Sep '09

07 Sep '09

Hey, After discussing with Ævar, we agreed that using the Maps extension [0] instead of SlippyMap to display OSM maps with OL is probably a good idea, assuming this is doable of course, which I think it is. I am able and willing to put quite some time into making the needed changes to Maps. Before I can really start though, it would be helpful if I had the most up to date code of SlippyMap, since a lot of it's current code can be re-used. Is this the one committed to the SVN trunk? (I've downloaded that code, but it's missing at least one file and giving other errors as well.) It would also be nice if the people who are working on this end of the mapping effort give me a poke, so efforts can be coordinated, and no one goes off to create duplicate or redundant functionality. If anyone has objections to using Maps instead of SlippyMap, please voice them, so we can discuss the advantages and disadvantages of using Maps. These are as I see it the most important functionality to-do's: * Migrate code from SlippyMap to Maps, mainly the static map handling * Add the ability to display maps without any markers on them. Currently maps has several parser functions, like display_point, which will display an error when you don't provide any coordinates instead of displaying an empty map. (Should be easy to do though.) * Optimize the code. Currenly Maps supports OpenLayers as mapping service, and allows you to display maps from a variety of mapping services. On top of that, the OL JS is far from optimal. Therefore I think it's best to simply add a new service to Maps (this is done via a hook-like system build in Maps), and create optimized handling for only OL+ OSM there, based on current SlippyMap JS. * Optionally (probably not required in the first version) add image-as-layer capabilities, allowing users to zoom and pan around high resolution images. Anything mission critical I'm missing there? [0]http://www.mediawiki.org/wiki/Extension:Maps Cheers -- Jeroen De Dauw * Forum: code.bn2vs.com * Blog: blog.bn2vs.com * Skype: rts.bn.vs -- Don't panic.

Dynamic POIs
by Jorge Chamorro 03 Sep '09

03 Sep '09

During the wikimania 2009 I was following this work : http://wiki.openstreetmap.org/wiki/OpenLayers_Dynamic_POI for wikimania - openstreetmap collaboration Please first check this url : http://osm.chamorro.com.ar/dpoi/ At this url you can see cassini localized tiles with info extracted from download.dbpedia.org dumps At low zoom levels we have a lot of info then we need to limit the info per tile. Now I use a random value but then I use anything else Limit it by category/subcategory/search keyword it's fine but I want to improve the system for a large number of points at this time. There are languages without tiles because I generate the index page from a list from dbpedia. Data are probably not correctly passed too This is a work in progress . -- sorry for my poor English --- I based my work on a minimal example . A more complex is here: http://www.freemap.sk/ Saludos , Jorge

(CC-ing maps-l) (I'm currently at Wikimania 2009) Yes, we're planning on keeping them up-to-the-minute eventually. The system on cassini was/is just a prototype pending the setting up of the real database/rendering/tile servers. We've just got access to those servers and hopefully we'll set them up properly with automatic updates soon. But I can't promise anything. But hopefully we'll get it properly running in September.

Announcemen: Multilingual Country-List
by Peter Körner 24 Aug '09

24 Aug '09

Hello OSM folks For the integration of osm into the wikipedia there will be localized maps in all languages that have their own wikipedia. The problem is, that a lot of countries are not translated yet. To get an overview over the status and make translating those countries more easy, I created a tool that can be found at http://cassini.toolserver.org/~mazder/multilingual-country-list/ I'd like to encourage everyone to spend some time making translated maps better. Comments welcome! Peter

Populated the spatial_ref_sys table on cassini
by Peter Körner 24 Aug '09

24 Aug '09

Hi Just want so note that I populated the spatial_ref_sys table on cassini as explained at [1]. This makes it possible to transform between different coordiante-systems using postgis. Peter 1: http://lists.openstreetmap.org/pipermail/talk/2009-August/040851.html

Server setup update
by Brion Vibber 21 Aug '09

21 Aug '09

Quick note -- It seems there's been a long serious of miscommunications and dropped handling of access & software setup for the mapping servers, which has led to some very unhappy people. :( I want to make sure we get this sorted out in the next few days... for the moment we're collecting notes on what actually still needs to get set up here: http://meta.wikimedia.org/wiki/Maps_server_setup_tasks Once we've got that down to a clear checklist and know who needs to do what I can bash people on the head until it happens. :) -- brion

Map project architecture
by Marcin Cieslak 19 Aug '09

19 Aug '09

Hello, I have added some thought on the overall solution architecture - most importantly, I have added some questions and decision we should think of before fully deploying servers (being that WMF or Toolserver's): http://meta.wikimedia.org/wiki/Maps_server_setup_tasks#Architecture%20and%2… I think it is important to think "out of the box" here and think about those issues leaving low-level discussions (cassini vs. ptolemy vs. whatever) aside for a while. One of the important steps would be getting stats on the current geohack and WMA usage. -- << Marcin Cieslak // saper(a)saper.info >>
