Use of textures for conveying information. a For immersion, aerial imagery can be shown mapped onto the surface. Here, the city of Kiel is depicted with a texture at a much higher resolution than the surrounding region. b Additional information, such as heat demand density of building stock (in \(MWh/(ha \times a)\)), can be easily conveyed using textures as well. c Again, a higher resolution texture has been applied for the city of Kiel, showing heat demand density at a \(1\,ha\) resolution while the general texture for the state has a resolution of \(1\,km^2\)
