OpenStreetMap 3D
by Thomas Baeumer 12 Mar '09

12 Mar '09

Moin, habe ich gerade auf howtoforge.de gelesen: In einem Forschungsprojekt der Universität Bonn ist eine neue, dreidimensionale Landkarte von Deutschland entstanden: Die Geowissenschaftler haben Daten der freien Weltkarte OpenStreetMap (OSM) mit den 3D-Geländedaten einer Space-Shuttle-Mission verknüpft. Die Expeditionsergebnisse der Shuttle Radar Topography Mission (SRTM) stammen aus dem Jahr 2000, als das Space Shuttle Endeavour mit einem aktiven Radar Teile der Erdoberfläche abgetastet hatte. Das Ziel: Gewinnung der Höhendaten des Planeten. Das geht mit der virtuellen Deutschlandkarte: - Nutzer können topographische Gegebenheiten (Gebäude, Berge, Täler) dreidimensional sehen - Ein Zoom in die Ansichten ist möglich - Städte oder Flüge können virtuell erlebt werden - Nutzer können auch hier nach Adressen suchen - Anzeige von Points Of Interest (POI): Sehenswürdigkeiten, Bus- und Bahnhaltestellen, Geldautomaten, Einkaufsmöglichkeiten - Anzeige bestimmter Lichtverhältnisse an bestimmten Orten zu bestimmten Zeiten Die Navigation funktioniert über Schaltflächen am oberen Bildrand der Karte. Hilfe ist via eines Fensters am linken Bildrand abrufbar. Nutzungsvoraussetzung ist das Java-Programm XNavigator. Schade: Noch sind die Gebäudeansichten der 3D-Städteansichten nur als Klötzchen angezeigt, die aus Informationen über Grundrisse, Höhe oder Stockwerkanzahl errechnet wurden. http://www.howtoforge.de/news/allgemein/deutschland-jetzt-dreidimensional-o… Gruss Thomas -- thomas baeumer thomas(a)ctrl-c.de zwischen mut und dummheit liegt nur ein grat der sich durch das vorbereitetsein unterscheidet

Fwd: [OSM-talk] License to kill
by Florian Lohoff 04 Mar '09

04 Mar '09

Fuer die die nicht vor seitenweisem Englisch weglaufen. Steve schreibt was zu den endlosen debatten bezueglich dem Lizenzwechseln von CC-BY-SA auf irgendwas anderes (ODbl). Probably worth reading ... Flo ----- Forwarded message from SteveC <steve(a)asklater.com> ----- From: SteveC <steve(a)asklater.com> To: Talk Openstreetmap <talk(a)openstreetmap.org>, "Licensing and other legal discussions." <legal-talk(a)openstreetmap.org> Date: Tue, 3 Mar 2009 20:28:32 -0800 Subject: [OSM-talk] License to kill Where to begin? Why don't we start with the beautiful community we've built and the stunning map can be the backdrop. On this canvas lets spread the pieces of the puzzle and see if we can put a few things together. We have incredible coders. We have mappers that stay up all night adding lakes in Bolivia from aerial imagery. We have people building community across mailing lists, forums and mapping events. We have user interaction people. We have stunning cartography from the planets best cartographers. We have a sysadmin team second to none. We have a volunteer board doing their best with the tools they have. We have fake bloggers so involved in their espionage they fake their own retirement and write in a different tone so you don't think it's them. But, we don't have a shed load of intellectual property lawyers with aeons of experience. Now that's important. Laws and licenses tend not to be written by sysadmins. Or Cartographers. Or even expert C++ coders. We're a funny bunch, us hackers. We can deconstruct a problem and code around it. We can avoid logic traps. Every day we decompose algorithms and we have no hierarchy other than our code. Is your code better? Then you're better. Am I a better coder if I have a degree in computer science? Probably not actually. But if I have 10 years hacking on Apache or something... then I have a flag to fly. And the wonderful thing about our skill as coders is that it applies to a lot of other area. We can make electronics if we want. Many of us know quite a bit about Physics or Chemistry. We know that coding is basically mathematics [5] so we tend to be good at that too. That logic and intuition we learn as coders is just incredibly powerful. We're like wizards with the secret spell and often the world lays as an open book to us, and we need not turn the page to know the ending of a story. Because we figured it out two equations ago. Or it's just like that other coding problem we worked on a few weeks ago. Or actually, it's like cantors diagonal slash[6] and we can use that. Maybe if we treat the engine as if it were a misbehaving piece of code[4] we can figure out the issue just by being scientific. And that's amazing. It's stunning. It's jaw-dropping. We see the world a different way, and we build incredible things like wikipedia, or GNU/ Linux. Or we hack together a windscreen wiper which pauses between wipes [8]. Or a vacuum cleaner that needs no bags [7]. All that incredible skill very often, sadly, counts for nothing when we want to become managers. Or write licenses. Or diagnose our own illnesses. Or fall in love. All that logic and training doesn't help. And we really, really don't like that. We don't like to talk about it either. It's an Outside Context Problem [1]. It's the boundary of our world. It's Godel, Escher, Bach[2]. It's the knowing that there is something outside of our System of the World[3]. We can't use C++ to manage people. We can't use logic to fight with a 2 year old having a tantrum. We can't use the scientific method when having an argument with our girlfriend, or boyfriend. And I'm going to have to disagree with many of you respectfully that all your coding, or writing, or mapping experience makes you a qualified lawyer. Why? Not because you don't have a degree in law. Let me say that again - I don't disagree with you because of your qualifications... just like I wouldn't disagree with you over a coding or logic problem if you don't have a degree from MIT or Cambridge. Law is about three things (at least in the societies I've lived in). One of them you can nail. You can nuke it from orbit. You will win like some vast chess match. The bit you can win is the logic. The logic of law, of licenses, of contracts... that is trivial. If the contract says pay peter £100 or $10 or €1 if he paints your bike shed blue then your logic will pay him. If there is a get out clause buried under mounds of legalese you can find it. You will exploit it. You will win like a champ. I have utterly no doubt. I've used it. I've sued people and I've won. And they deserved it. But what you don't have with all your power and logic is a understanding of case law. This would be pillar two in Steve's Understanding Of Law. This is where it all falls apart. Because where all that logic breaks like the crumple zone on a Ford Escort hitting a tree, is the real world. Logic dictates we should lock up 12 year old girls for infringing the copyright of Michael Jackson. Logic dictates we should lock up terror suspects without trial. Logic dictates breaking a copyright protection mechanism is a criminal offence. And that's all a bit crazy. Because here's where logic meets opinion. And that opinion is called... case law. Case law says, lets not bring the same thing to court lots of times. That's expensive and dull. So if this case here, lets call it A is like that case over there... B. And A was decided like this... and A is really like B... then B should be decided similarly to save a lot of time, effort, hassle, money, dullness. It turns out that if you watch movies about the cool lawyer saving the day they often spent 3 years looking at obscure case law from 1834 [9]. They use this to show the case is like that other case over there... and win. So why is it so hard and expensive to become a lawyer and why do they think they are so cool? Because they have a magic power and they are wizards just like you, but their power reins over a different domain. Sometimes you may clash and sometimes you may win. In general though, you are better at debugging than they are and they don't know anything about gcc compiler options. In turn.. .you don't have an in depth knowledge of intellectual property law or that case that was just decided last week by the supreme court. They, the legal guys, will read things like "s/foo/bar" and think it's s divided by foo, divided by bar. You may read "Without prejudice" [10] and think "great now we can have a conversation and not worry about the threats". All their power and majesty counts for nothing in our world. And all of ours for nothing in theirs. But it's not like we're not motivated right? We have money, we have time, and we have some of the smartest people on the planet and we can defend ourselves with dignity and grace as the pirate bay folks are doing right now. And we can attack when we want. But often we join up with lawyers who are really secret coders. They're pretty bad coders. But they give us some help and we give them interesting dwarves to slay and some street cred that they're friends have powers in another dimension to theirs. So on occasion, we help each other. This is one of those occasions. We have two of the most capable legal guys on the planet in this domain trying to help us. They want us to win. They want to see us take off and not fly on vapour. But what do we do? We blame Steve because he's evil. We blame the process because it took too long. We blame the working group for not being quicker. We figure the foundation must be culpable. We write long rants about how it's a dire emergency... But pause for a second. Close your eyes, take a deep breath. Open them and look around. Oh... there's that massive community we've built. Look over there, it's an amazing map we've built from a blank canvas in to the most stunning, best, most fantastic map on the planet. Birds are singing. Honestly. An angelic choir descends and something akin to the ITO! animation explodes and dances in front of you, completing a map of the world for free in front of your eyes. For *free*. For __FREE__. Now lets turn to the board and the working group. They're volunteers.. but they haven't been doing their job! They've been slow! It took them so, so *so* long to get things done... But hold on nobody has been saying they could have done better... oh and we don't see any offers of help.. or offers to be on the group. Because it's a bit easier to stand on the sidelines and we like it here. But lets just question them, their reputations and priorities anyway... after all they deserve it for volunteering. Oh... hang on a minute most of the delay was actually due to consultation between lawyers in the other dimension. The other land where it's ok to take time to review legal processes in a quiet, informal, slow and deliberate way. Like how it's done by actual 'real' lawyers in actual 'real' legal firms. But! Hold on! We should see every draft of the license! Every time they add a comma, or review something! Every sentence! You're taking away our rights you evil volunteers! Yes we should in the same way that a lawyer should comment on your C++ or ruby code after every 20 characters. They should comment on your mistakes, your lack of foresight. They should publish widely. They should blame you when it doesn't compile because you left off a semi- colon. If a function is half written, so be it! Release it anyway. But we don't tend to do things like that, do we? We do things like release the code by doing a subversion checkin... when we're reasonably happy with the code we've done. Ladies and gentlemen you just saw a subversion checkin of the license. Now you can blame me for being sometimes a little overzealous for allowing them the privacy and time to complete their work.. but I have a lot of respect for them and a lot of time for them. I believe by showing that we understood them. That I knew what I did not know. That I knew I wasn't a lawyer. That we weren't going to slap them with 300 emails on every release... that we built something better. You can disagree with me. You can point to the projects you've built with 100,000 people in them. You can point to your legal buddies who are better than mine... but that was the decision I (and by the way the license team and the board) went with. Lets look at the other reason we did that. On any objective measure, legal time is worth more than my time. The last time I had to sue someone because the infringed my copyrights the guy was charging £250 an hour. An hour! Insane! So every hour they spend looking at your comments is an hour not making the license better with the peer review from another lawyer. Or making £250. And they're doing this for us for free. If you were paid £250 an hour and worked for free for someone on the side... would you like to work on the Space Shuttle or a bicycle? Because what you're asking them to do is work on your bicycle because it doesn't have rocket engines. You don't understand enough about bicycles to know they traditionally don't have rockets attached and so you take up a lot of their time arguing about rockets... and not about your flat tyre. They're far too polite to say this of course. But, and you know this, we listened anyway. We worked hard to build a home around the license. Somewhere to vent your frustrations. We built another comment period in. Again. Jordan will take a look at your rocket plans and space lasers. he will take a lot of time and distil it down in to a puncture repair kit. And you know what the license will be better for it. And he'll thank you for it. And we will all be better off. So lets concentrate on that. Lets build a better process. Lets build a consensus. Lets understand that they know more about law than we do and act in a humble and respectful way. Lets help and become a volunteer. Lets put all these good ideas in to a plan. And lets build a better project. Notes ===== * I'm well aware that the above doesn't cover every single issue raised like whether you have a crack team of intellectual property lawyers ready to spring in to action, or you're not a coder. The above was a vast set of metaphors, taking it literally implies you're not cognizant of that. Re-read the stuff about logic not applying totally to love, management, law, war and so on ad infinitum. * Stop thinking that CCBYSA applies to OSM. It doesn't very well at all. Richard Fairhurst can tell you the 3.29 billion reasons why * Stop thinking Steve is Evil and out to own the license. If you spent more than 34 seconds thinking about it you'd realise that the best possible route for him would be Public Domain so he could do whatever he wanted. Really. Think about it. In fact I truly believe viral is better for the health of this project and I've fought hard against my own self interest on this. * Why hasn't Steve responded in 3 days and rah rah rah. Because I'm taking time to digest all your comments and it takes time because there are so many, there are repeats and there is the personal stuff to distil out. Best Steve [1] see iain m banks [2] see hofstadter [3] see neal stephenson [4] see the zen of motorcycle maintenance [5] see turing or danny hillis or the diamond age [6] its really scary, see GEB [7] see dyson and his book [8] see flash of genius [9] see good will hunting [10] you really, really need to look that up if you don't know what it means _______________________________________________ talk mailing list talk(a)openstreetmap.org http://lists.openstreetmap.org/listinfo/talk ----- End forwarded message ----- -- Florian Lohoff flo(a)rfc822.org +49-171-2280134 Those who would give up a little freedom to get a little security shall soon have neither - Benjamin Franklin

Volkslauf Harsewinkel
by Florian Lohoff 03 Mar '09

03 Mar '09

Hi, ich habe gerade vom Organisator des Volkslauf in Harsewinkel eine Message ueber OSM bekommen. Der bekundet interesse die Volkslaufstrecken (verschiedene Laengen) zu erfassen. Das ganze ist ja mehr eine Fleissarbeit als wirklich eine Intellektuelle Herausforderung aber vielleicht finden sich ja Mitstreiter. Schritte waeren dann: 1) Erfassen des Straßennetzes auf dem der Volkslauf stattfindet Harsewinkel ist da noch ein wenig Mau - ist aber nicht so gross das man das nicht mit 2-3 Mann an einem Wochenende hinbekommt. 2) Eintragen der Strecken via Relation (route=pubrun oder so) Einfach ein wenig kreativitaet mit den tags so das 3) das wieder rausbekommt. 3) Visualisierung ueber einen mapnik + slippymap Jetzt wo es einen konkreten Anlass gibt - wer hat lust auf eine Mapping Party in Harsewinkel? Gibt es dort vielleicht ein nettes Kaffee das WLAN anbietet?

OEPNV-Karte in OpenLayers
by Frank Jäger 21 Feb '09

21 Feb '09

Hallo, ich möchte auf meiner Homepage mit Startposition auf einen Ort die verschiedenen Darstellungen von OSM-Daten zeigen. Auf http://www.fotodrachen.de/osm_lemgo.htm sind das neben "Mapnik" und "Osmarender" zur Zeit die "Radkarte" und (als Overlay) die "MaxSpeed-Karte". Später sollen noch die "Wanderkarte" und ein "OSM-WMS" mit UMN-Mapserver dazu kommen und was sich noch so entwickelt. Seit einiger Zeit kämpfe ich nun damit, die "ÖPNV-Karte" dort einzubauen. Hier unsere Salzufler "Paulinchen-Bahn": http://www.öpnvkarte.de/?lat=52.09205&lon=8.75324&zoom=15 (Sie wird gerade wieder flott gemacht, denn ab 1. März fährt sie wieder) Das Besondere daran ist: Bis zur Zoom-Stufe 13 ist es ein vorgerenderter gekachelter Dienst. Da der kleine Server damit überlastet wäre, auch für alle feinen Zoomstufen Kacheln auf Vorrat zu rendern und zu speichern, übernimmt ab Zoom 14 ein WMS (Web Map Service). Der rendert erst auf Anforderung. Nicht als Kacheln sondern den kompletten aktuellen Karteninhalt. Also "Ein Thema" in der Auswahl = 2 Dienste. Dieser Sonderfall ist bei OpenLayers nicht vorgesehen. Ich versuche, das über Events abzufangen und zwischen Zoom 13 und 14 zwischen den beiden Diensten zu wechseln, möglichst unmerklich für den Anwender. Da ich mich mit Java etwas schwer tue und wenig Erfahrung mit OpenLayers habe, bekomme ich es bisher nicht hin. Der erreichte Zustand ist in folgenden (versteckten) Entwicklungsversionen: http://www.fotodrachen.de/osm_lemgo_dev.htm http://www.fotodrachen.de/javascripts/map_dev.js Ich lasse Informationen über die Events in eine Firebug-Console ausgeben. Auf der Originalseite werden keine anderen Themen gezeigt. Es gibt daher keinen LayerSwitcher. Es braucht nur der Base-Layer gesetzt werden. Hier muss man aber beim Umschalten überwachen, ob "das Thema" gerade eingeschaltet ist. Kann einer von euch erkennen, was ich hier falsch mache? Manchmal erscheinen beide Einträge im Layer-Switcher. Manchmal sind sie augeschaltet, obwohl die Karte sichtbar ist. Zoomt man rein (>13) und dann wieder raus, wird der gekachelte Service nicht mehr angezeigt. -- Frank Jäger |\__ (:> __)( |/ http://www.FOTODRACHEN.de

Hallo, gestern beim User-Treff wurde kurz das Thema "OSM in den Medien" angesprochen. Dazu möchte ich noch den Vortrag von Frederik Ramm nachreichen: http://chaosradio.ccc.de/24c3_m4v_2286.html Besonders interessant finde ich die Feststellung, dass Kartenmaterial und die Kontrolle darüber auch eine Form von Macht darstellt. Über Links zu anderen interessanten Berichten würde ich mich freuen. @Carsten: Ist das Foto schon irgendwo online? :) Grüße, hendrik
