Beside the impressive, 25 km high shield volcano Olympus Mons on Mars there are many more famous Mountains and Regions. Many of the mountains, valleys and regions on Mars have been exacty surveyed by photogrammetry. The 3d-models of regions are called digital terrain models (DTM), with which pictures from every perspective can be computed or also fly-over videos.
This does not hold true for the so-called 'Face of Mars'. Admittedly there are land relief data and images of this mountain, but in diverse ranges they all have unvalued details or untreated erros. As an oronym we continue to use the term 'Face of Mars'. As an example für pareidolia the Image from Viking Orbiter in 1976 is the wrong Image, because on the first fotos the mountain indeed looked like face lying half in shaddow. On recent fotos this is completly different, they do not show the appearance of a face. Only people who mean to identify a face on newer fotos may labour under pareidolia. But this mesa has other features which are not usual for natural mountains.
This project is aiming at a precise 3d-model for the so-called 'Face of Mars' in the frame of world space week 2015. Now the model consists of 126 Points in 3d space and our aim is to increase this number up to 1000. With such a precise 3d-model analyses can be done better. For example, it is possible to illuminate the blank land relief from different directions and to look what impressions the play of light and shadow leaves in the human visual apparatus, and to evalue this with the knowledge of optical illusions.
