Blue Marble: A Method for Visualizing Giga-Pixel Layered Imagery for Tiled Displays
we present a technique for the interactive visualization and interrogation of multi-spectral giga-pixel imagery. Co-registered image layers representing discrete spectral wavelengths and temporal information can be seamlessly displayed and fused. Users can freely pan and zoom, while browsing through the data layers enabling intuitive analysis of the massive, time-varying, multi-spectral, records. A data resource aware display paradigm is introduced that progressively and adaptively loads data as it is needed from remote storage, at the level of resolution supported by the used display device. The result is a highly scalable approach, equally suited for a laptop or ultra-high resolution displays system operating at hundreds of mega-pixels resolution. Different case studies are presented which show the systems utility in the context of geo-referenced and biometric data, as well as analysis cultural artifacts. ()
