For further maintenance of the medieval fortress it seemed necessary in 1997 to start a serious renovation of the whole complex of the various buildings. To record and document the situation before and compare it to the status after the renovation a photogrammetric recording was initiated. We used some of the existing data of this documentation and(More)
The Photo-Compact Disk, introduced by KODAK in 1992, will become a very important tool for every photogrammetrist using digital images. The maximum resolution of 2048 x 3072 pixel referring to a 24 x 36 mm negative image, that is equivalent to an absolute value of about 12 micrometer, leads to the expectation of a high quality standard. The presented paper(More)
In early 2007 the special research program HiMAT – History of Mining Activities in Tyrol – was established at the University of Innsbruck. It is an interdisciplinary research project dedicated to the history of mining in Tyrol and adjacent areas, sponsored by the Austrian Science Fund (FWF). At present, the Surveying and Geoinformation Unit of University of(More)
As one method of surveying seldom meets all needs for recording complex shapes and surfaces of a historic building, a combination of methods (tacheometry, photogrammetry and manual measurements) has often to be used. Each of the methods has its advantages, either in easy recording of global structures or in contributing a high level of details so a(More)
Terrestrial laser scanners have achieved a great popularity in the last decade. Their easy on-site application and the possibility of a flexible and high quality post processing added to their success also in architectural, archaeological and heritage documentation. We present a method for handling the automatic registration of point clouds which are(More)
Mining plays a very important role in the history of man. From the very beginning man's development has been accompanied by the extraction, processing and utilization of mineral substances. In the past, mining often exerted influence on economic, social, legal and cultural structures within society. The technological aspect must be emphasized as well, for(More)
The original non-metric photographs of Antonio Gaudi's model dating back to about the year 1900 have been detected some years ago in a Catalonian architectural archive. These are probably the last existing ones because the rest of them had been destroyed during the Spanish Civil War in the 1930s. The problems during this first scanning of these outstanding(More)
A wealth of information on cultural heritage coming from archaeological investigations exists in the form of geometric information. Here we want to question how this geometric information relates back to the reality it was intended to document. Building upon the CIDOC CRM-an ontology to represent data for cultural heritage-we apply CRMgeo, an extension to(More)
For the documentation of complex objects different surveying techniques are available. Sometimes a single method is insufficient to capture the entire object. In most cases only one acceptable measurement method is a priori selected and defines the kind and resolution of the collected data. For an enhanced 3D documentation of complex objects the acquisition(More)
