One of the most important finalities of survey is the architecture's comprehension. To the end of cultural heritage conservation, it is furthermore necessary to communicate the acquired knowledge. In the recent years, this need has resulted in a radical change in cataloging and digitization systems, as well as in telematics networking. Moreover, the use of 3D laser scanner has transformed not only the approaches related to metrics data acquisition and graphic rendering but has also afforded the opportunity to share important information on the web. This paper focuses on the usefulness of state-of-the-art technologies for documentation, presenting a case study related to the architectural-archeological area of Aruch in Armenia.
