OpenStreetMap in 3D - current developments

  1. 1. OpenStreetMap in 3D current developments Arne Schilling 3rd Internation MapWindow Open-Source GIS Conference Velp, The Netherlands, 06/26/2012
  2. 2. Outline• Part 1 – What is OpenStreetMap 3D? – 3D Community – Data Capturing – Data Editing & Processing• Part 2: – OSM-3D Project – As Browser Plugin – Database Statistics – Web Frontend – External Authoring Interface – As Standalone Application – Open Service based Infrastructure
  3. 3. Part 1: What is OpenStreetMap 3D?• Community project, part of OpenStreetMap• Volunteered Geographic Information• Using existing OSM database, add specific 3D information Server OSM Mappers Guidelines Renderers Infrastructure
  4. 4. 3D Community• Current activities GLOSM OSM2World: oblique imagery OSM in X-Plane Kendzi3D XML3D: Declarative 3D osm-3D.org
  5. 5. 3D Community• 1st Workshop in Garching, Germany, 27. August 2011: 5 participants from universities• 2nd Workshop in Garching, Germany, 17.-18. March 2012: 16 participants from universities and the industry• Topics: – Data Capturing – Data Editing & Processing – Visualization & Applications – Visions and strategic concepts – Communication & Infrastructure – Tagging consolidation
  6. 6. Data Capturing• Professional Workflow requires – Cadastre data – LIDAR for producing point clouds or high res camera for producing oblique imagery – Plane? – CAD and other professional Source: 3D Reality Maps reconstruction tools - efficient but very expensive Source: Vertex modellingSource: virtualcitysystems
  7. 7. Data Capturing • Workflow for amateurs – Using handheld GPS devices, smart phones – Observe from street level – Trace/measure from Bing maps at home – Use other public domain informationSource: Gadgeteer.org Source: Heiko Schlesinger Source: OpenStreetMap Source: gabrielhemery.com Source: Wikipedia
  8. 8. Data Editing & Processing• 1. Approach: – Using existing 2D editing software e.g. JOSM – Describe building shape using attributes – Rule-based reconstruction Source: Wikipedia Source: osm-3d.org
  9. 9. Data Editing & Processing • 1. Approach: Rule-based reconstruction – Vertical gaps: skybridges, overpasses, overhanging partsPetronas Tower Skybridge Connecting passageSource: Wikipedia Source: Wikipedia Source: OpenStreetMap London City Hall Source: Wikipedia Source: osm-3d.org
  10. 10. Data Editing & Processing• 1. Approach: Rule-based reconstruction • Describing Roof shapes using attributes • Definition of typical roof shapes • Adding additional information: angles, heights, orientation, material, gables, etc. • Plugins for 3D preview Source: Kendzi 3D Source: osm-3d.orgSource: OpenStreetMap
  11. 11. Data Editing & Processing• 1. Approach: Rule-based reconstruction • Limitations: Data imported from french cadastre Source: OpenStreetMap Data source: cadastre-dgi-fr source : Direction Générale des Impôts - Cadastre. Mise à jour : 2010
  12. 12. Data Editing & Processing• 2. Approach: – Using 3D Modelers / CAD software – Requires dedicated 3D repository/servers – Objects in 3D repository are linked to OSM via URLs (Tag building:model=„http://repourl/model.wrl“) – OpenBuildingModels Source: osm-3d.org
  13. 13. Data Editing & ProcessingCombining rule based reconstruction and OpenBuildingModels
  14. 14. Part 2: osm-3d.org
  15. 15. As Browser Plugin
  16. 16. As Browser Plugin
  17. 17. As Browser Plugin• Link from geocoded Wikipedia article using GeoHack template http://www.osm- 3d.org/map.htm?lat=51.983333&lon=5. 916667&zoom=12
  18. 18. Database Statistics Worlwide coverage400 GB terrain data / 69 Mio. tuples 54 Mio. buildings1,4 TB processing database
  19. 19. Web Front End• Technology: – Mix of Javascript and Java Applet – Rendering based on OpenGL / JOGL – Address Search and Routing functionality provided by OpenRouteService – Java Applet has External Authoring Interface
  20. 20. External Authoring InterfaceJava Applet methods can be called from Javascript using LiveConnectFunctions available for- Adding own markers (waypoints) with custom text and icons- Controlling camera, adding viewpoints- Enabling/disabling layers- Computing routes- loading custom models stored locally- Replacing Geocoder or Route Service
  21. 21. External Authoring Interface<applet id="xnavigator" code="org.gdi3d.xnavi.appletlauncher.AppletLaunche r.class" WIDTH=800 HEIGHT=570> ... </applet>document.xnavigator.setLayerSelected(„PublicFacilities“, true);document.xnavigator.addWaypoint(5.92, 51.98, „4326“, „http://myiconurl.png“, „center“, „middle“, „myWaypoint“, „id01“);document.xnavigator.addViewpoint(6.93, 52.34, 100.3, 0.0, .0.32, “from south”);document.xnavigator.importURL(„http://myurl/myBuilding.wrl“);Documentation:http://xnavigator.sourceforge.net/doku.php?id=eai
  22. 22. As Standalone Application• Access to advanced features: • Upload of GPX tracks • Search for nearby POIs via OpenLS Location Service • Route animations • Import custom 3D models • Load data from Web Feature Service • Control of solar and atmospheric settings
  23. 23. Open Service based Infrastructure ?GE, Nokia, other ?closed sourceProducts GE Server Prop.Open Source Images,Projects vectors NASA World Wind Server OGCOSM-3D 3D Formats W3DS
  24. 24. W3DS Server Interface• Get Service Meta Data: – http://rax.geog.uni- heidelberg.de/W3DS_OSM/W3DS?SERVICE=W3DS&REQUES T=GetCapabilities&ACCEPTVERSIONS=0.4.1• Get Buildings: – http://rax.geog.uni- heidelberg.de/W3DS_OSM/W3DS?SERVICE=W3DS&REQUES T=GetScene&VERSION=0.4.1&CRS=EPSG:900913&FORMAT =model/vrml&BoundingBox=790053.1172,6572361.3988,790664 .6134,6572972.895&layers=Buildings

  26. 26. Conclusions• OpenStreetMap contains a lot of hidden information that is useful for various purposes. Map -> spatial database• Concepts and guidelines on how to map 3D information in OpenStreetMap are still under development• The osm-3d.org web page provides already a usable service• The architecture is very flexible and can be used for other projects as well, it is not tailored for OpenStreetMap
  27. 27. The End• Any questions? Arne Schilling 3rd Internation MapWindow Open-Source GIS Conference Velp, The Netherlands, 06/26/2012
  28. 28. Since 09/2011: Terrain available worldwide
  29. 29. Since 02/2012: Bing Maps and Bing aerial imagery
  30. 30. Google Earth Integration
  31. 31. Web Site Usage StatisticsUnique visitors per week of http://osm-3d.org Traffic from Wikipedia / GeoHack
  32. 32. XNavigator DownloadsDownloads per month
  33. 33. Server Interface• OSM-3D data can be accessed without credentials• Interface based on Web 3D Service: http://w3ds.org• Output formats: VRML, X3D, KML, COLLADA, XML3D
  34. 34. Various Terrain Styles
  35. 35. Since 03/2012: Buildings & POIs available worldwide
  36. 36. Building Updates• Set up automatic update process• Updates are done weekly or biweekly• Osmosis database updated using OSM change sets• PostGIS database updated weekly baed on change sets• 3D buildings generated from PostGIS database. Full update of all buildings OSM OSMOSIS PostGIS 3DChange Set database database database
