“…Terrestrial laser scanning technology is a method that samples or scans objects directly, precisely and automatically obtaining 3D coordinates (x, y, z) with the help of LiDAR technology (Beg, 2018;Bonfanti et al, 2013). It is based on a system that scans the target object in series of points within limited angles in horizontal and vertical directions and enables it to be displayed as point clouds (Lichti & Gordon, 2004).…”

“…Using 3D point cloud data obtained by laser scanning method, the following studies can be performed through CAD applications: basic measurement data, orthophoto image extraction, 2D or 3D drawings, solid surface models, 3D animations, texture covered 3D model extraction. It is seen that high resolution 3D point cloud data is used in architectural survey studies, in the production of orthophoto to ready for CAD drawing (Hassan & Fritsch, 2019;Lin et al, 2019;Bonfanti et al, 2013). In this study, 3D CAD drawings of Ali Efendi Muallimhane, one of the historical and cultural works of Konya province, were created from high resolution 3D point cloud data and their orthophotos.…”

Preserving historical and cultural artifacts through generations is essential for maintaining the roots and ensuring the development of any civilization. Conservation and restoration works are crucial in order to save numerous historical and cultural heritages in our country and the world and also pass on them from generation to generation. Nowadays, the increasing development in measurement technologies and the integration of photogrammetry into architectural applications have provided different perspective in architectural documentation applications. In this context, Terrestrial laser scanning method is a current method used in documentation studies today. The most important advantages of terrestrial laser scanning in this study are as follows: -the point cloud data obtained by terrestrial laser scanners provides the opportunity to reach the correct data at the desired frequency in a short time, -obtaining appropriate and practical results for the targeted study,-the possibility of using scanners in different working areas. In this context, laser scanners have become one of the popular methods in which effective and successful results are obtained in architectural documentation projects such as survey, restitution and restoration. Within the scope of this study, ''Ali Efendi Muallimhanesi'', which is one of the historical and cultural heritage of Konya province, was scanned with a terrestrial laser scanner and 3D drawing and modeling was carried out with the help of the cad-based modeling tools only using 3D point cloud data.

“…In the field of archaeology, or generally in CH, laser scanners (triangulation or time-of-flight) and structured-light systems were very successful, making easier the acquisition process of data related to the geometry and shape of both simple and more complex structures Tucci et al 2013;Bonfanti et al 2013). Generally, active sensors can provide directly and in very short time a huge amount of 3D data that are normally returned as a dense point cloud to which can also be added the radiometric value for each single point.…”

ABSTRACT:Highly accurate documentation and 3D reconstructions are fundamental for analyses and further interpretations in archaeology. In the last years the integrated digital survey (ground-based survey methods and UAV photogrammetry) has confirmed its main role in the documentation and comprehension of excavation contexts, thanks to instrumental and methodological development concerning the on site data acquisition. The specific aim of the project, reported in this paper and realized by the Laboratory of Photogrammetry of the IUAV University of Venice, is to check different acquisition systems and their effectiveness test, considering each methodology individually or integrated. This research focuses on the awareness that the integration of different survey's methodologies can as a matter of fact increase the representative efficacy of the final representations; these are based on a wider and verified set of georeferenced metric data. Particularly the methods' integration allows reducing or neutralizing issues related to composite and complex objects' survey, since the most appropriate tools and techniques can be chosen considering the characteristics of each part of an archaeological site (i.e. urban structures, architectural monuments, small findings). This paper describes the experience in several sites of the municipality of Sepino (Molise, Italy), where the 3d digital acquisition of cities and structure of monuments, sometimes hard to reach, was realized using active and passive techniques (rage-based and image based methods). This acquisition was planned in order to obtain not only the basic support for interpretation analysis, but also to achieve models of the actual state of conservation of the site on which some reconstructive hypotheses can be based on. Laser scanning data were merged with Structure from Motion techniques' clouds into the same reference system, given by a topographical and GPS survey. These 3d models are not only the final results of the metric survey, but also the starting point for the whole reconstruction of the city and its urban context, from the research point of view. This reconstruction process will concern even some areas that have not yet been excavated, where the application of procedural modelling can offer an important support to the reconstructive hypothesis.* Corresponding author.

ABSTRACT:The paper describes how new digital methodologies can be used within the field of Cultural Heritage, not only with the aim of documenting the actual state of an architecture but to review the past transformations it has undergone, conserving and representing these histories as well. The premise to conservation and enhancement of our Heritage is a deep study in terms of position, shape, colour, and also of the historical and artistic features. Survey methods have acquired data acquisition techniques in line with technological progress: today's electronic and IT technologies, that are the tools of modern Geomatics, allow the effective survey and representation of 3D objects, from architectural structures to sculptures or archaeological finds. Over the last few years, the methodologies of acquisition and integrated representation for 3D patrimony documentation have developed and consolidated considerably: the possibilities of the digital realm can augment the understanding and the valorisation of a monument. The specific case offered in the present paper, Ca' Venier dei Leoni, the palace where is the Guggenheim Museum in Venice, is a significant example. It suggests not only the theme of the "no longer existing", or better never built, but also the opportunity to formulate hypotheses regarding its implementation and the impact that the palace would have had in the Venetian contest * Corresponding author
