Abstract
The advances in 3D technology in the field of Cartography necessitate a reevaluation of howrnhigh relief topography has been and should be depicted. Autostereoscopic 3D, which does notrnrequire the use of external viewing aids in order for the subject to be perceived with a spatialrnimpression, and which has multiviewer capability is proposed as a desirable method.rnAutostereo-scopic 3D displays have the potential for improving not only the quality of the depictions,rnand increasing their availability for use by scientists or the general public.rnIn the theoretical portion of this study, autostereoscopy is defined and explained. Historicalrnmethods of autostereoscopic 3D presentation of high relief terrain, in the form of landscapernrelief models also known as solid terrain models (STM), are reviewed. An STM is createdrnwith these methods in order to understand the process and how it could be adapted to usernmodern technologies. Digital 3D models and the methods of generating them are discussed, inrnparticular laserscanning and Structure from Motion (SfM). Lenticular foil displays (LFD) arernpresented as an alternative method for multiviewer autostereoscopic 3D presentations.rnIn the practical portion of this study, two hybrid methods for creating autostereoscopic 3D depictionsrnof high relief terrain, each having a digital and a physical component, are suggestedrnfor experimentation. A project is carried out utilizing each method and the results are evaluated.rnThe importance of further research into these hybrid methodologies is discussed.
