V3EO – Visualization of 3D Earth Observation Products
Problems to solve: Extraction/preprocessing of EO big data; e.g.:
Decades of climate change data
Volumetric weather radar data (real-time)
Forecast meteo data
Efficient streaming of volume data
Interactive visualization (within web browser)
Goal: Development of an extraction and preprocessing pipeline
for volumetric satellite data

Volume Renderer
Contextual information(Terrain on ground plane)
Clear identification of Axis(Ticks, labels, units)
Data picking(Data navigation)
Interaction:
Slicing
Threshold
Rotation, panning

Voxel Cache
Creation of access-optimized structure based on original EO Data
Allow fast random access
Based on position; i.e. bounding box
Based on time interval
Provide initial low resolution data and streaming of additional higher resolution data
Additional time dimension to navigate temporal evolution

Vector Globe
Vector data visualization
Prevent issues related with visualization of raster data (re-projection)
Allow visualization of 3D data (e.g. magnetic field lines)
