What is Marble?
● Marble is a free digital globe application● ranging from the digital equivalent of an atlas to a simple interactive map widget
● for developers: easy widget which can handle all geographical needs for you

Usage
● KDE control center: timezones and location
● edu: kstars, kgeography● digikam: geolocation of photos● Worldtime clock plasmoid replacement● KOffice shape● Qt browser plugin

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

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

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

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

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
