Time space relief cartography was invented in 1993 to map the time-space contraction assuming the coexistence of fast and slow transport modes. Initially applied locally to terrestrial modes (1993 p. 41), the principle has been applied to urban spaces (1997 p. 209 and 235) continental scales (1994 p. 253) and to the air mode (2009). The next major step, an ongoing work, is to create a cartographic representation of the earth, the global time-space.
In 1994 in the CESA, spatial planning center of Tours University, the first time-space cartography took the form of an analog photo of a cathodic screen of European time-space, as shown on the image. The image was produced by Alain L’Hostis, by means of the computer program MapNod, from the indications of Philippe Mathis.
At that time the model is not finished as illustrated by the incomplete bottom of facets. A triangle is missing but all the networks are visible, since they form the structure on which the relief is drawn. Relief comes as a surface along the deformed road network. Three terrestrial transport modes are represented here: classic road, motorway (mode 6) and high-speed rail (mode 3).
By lack of available color printer in the CESA laboratory, analog photo of computer screen was one of the few possible options to realize this cartography. Later we used print-screen software to produce bitmap images, and even later developed the software MapNod to produce direct vectorial images in the WMF format.
