Cartographic Representations Of Historical Monuments Used In Digital Tourist Guide

Deploying multimedial tourist guides is a modern trend for an information support of tourists in the contemporary digital era. Classic printed tourist guides containing texts and pictures were transformed into their digital versions. But just texts and pictures seem to be not enough yet. A contemporary user wants to "see more", to have more opportunities how to get information from a guide. Thanks to the progress in ICT, especially in an improving performance of portable devices, augmented or virtual reality is being very popular nowadays. A crucial part of such a reality is in its 3D models, which are displayed on such devices. This contribution tends to compare two approaches, how to create such 3D models, especially models representing historical monuments. First approach is based on an automatic processing of images (i.e. comes from the field of photogrammetry) and the second is based on a more or less manual creation of 3D models using 3D CAD software. Comparison of both approaches is based on two models of the same monuments, one obtained by an automated approach and the second obtained by a manual approach. Pros, cons and limitations of both approaches are discussed with a focus on creation of historical monuments. It shows that an automated approach is not suitable for all situations and all kinds of historical monuments, especially when a historical monument exists not anymore.
