  5. 5. Patrick Spendrin --- aKademy 2008 5 Requirements & constraints ● small internal data set (~10 MB) ● downloadable: data for OSM1 , Wikipedia ● no hardware acceleration needed ● no other dependencies needed than Qt ● fast startup time (2-5 secs) compared
  6. 6. Patrick Spendrin --- aKademy 2008 6 Platforms & Portability ● Linux, Windows, Mac, Unix, Qtopia, WinCE ● first ones in KDE, Qt only version for all available ● extend easily with new maps: ● Precipitation ● temperature maps ● future project: earth-quake overview
  7. 7. Patrick Spendrin --- aKademy 2008 7 Temperature in July
  8. 8. Patrick Spendrin --- aKademy 2008 8 New plugin architecture ● providing really simple API derived from QPainter ● providing a way to access all data from the marble model ● even interactive plugins possible
  9. 9. Patrick Spendrin --- aKademy 2008 9 Ideas and soon to come ● vector tiles (my GSoC - see a bit later) ● OSM-namefinder ● NASA WorldWind source support ● marble on mobile devices – from N810 to Asus Eee PC ● routing support via openrouting.org ● view (and possibly change) gps data
  10. 10. Patrick Spendrin --- aKademy 2008 10 Vector Tiles ● Instead of image data use XML formatted data / binary caches of this structure ● Tiles will be generated form World Database sources (up to 250m/pixel) currently in use for image data ● Easily support OpenStreetMap later ● Output via independent rendering plugin
