A terra3D scene can consist of several two-dimensional and three-dimensional objects which may contain multiple overlapping information layers to visualize different types of data. Layers can be projected on a spherical, cylindrical or planar surface by applying different projections.
Earth and Clouds
The terrain is formed by an artificial height model of the earth. The data is colored by a colormap depending on the height of the terrain.Original infrared satellite photographs are used for this layer. Again, the data is colored by a colormap depending on the height (i.e. temperature) of the clouds.
Grid and Stream Data
A layer for grid points fields like temperature, uv radiation and ozone. Wind direction and force can be shown as arrows or as a particle system representing the stream process.
