5. CONCLUSIONS
The successfully application of single images in conservation has already a long tradition. So far little work has been carried out with
respect to a systematic research in this field. It is highly recommended and expected by the CIPA users community, to publish a
handbook for the use of single images in conservation, stating real useable practical advises and samples. The authors like to point
out, that they permanently gain practical experiences from "learning by doing", which is obligate in this field.
In this respect unexpected success gained from inventing the video based monument tachymetry on the one hand and from a
consequent applying of the low cost extremely low altitude photography by using a telescope beam platform on the other hand.
Both inventions have been stimulated by applying single images in conservation within the antic ruins of Patara(Turkey), even a
candidate for Atlantis. These both inventions promise a great future.
More than 150 years after the invention of the photography and applying digital photography even on an amateur level, for every
serous archaeologist, the time is more than overdue, to replace subjective interpreted manual sketches by objective high resolution
photomaps.
It is liked to emphasize, though medium range laser scanners show extremely dense but random surface points, early results, as
obtained with the callidus device at the University of Applied Sciences in Magdeburg, still suffer under unacceptable resolution and
are quite far away from a precise and detailed photo map.
