In this contribution the possibility to combine terrestrial laser scanner (TLS) measurements and UAS photogrammetry for the detailed description and high quality surveying of a cultural monument will be illustrated by the example of the Cathedral of St. Nicholas in the city of Greifswald. Due to the different nature of UAS photogrammetry and TLS walls and windows as well as portions of roofs are captured with a different level of completeness and accuracy. The average deviations of the test areas on the overlap between the two measurement methods ranges from 0.015 m to 0.033 m with standard deviations of 0.025 m to 0.088 m.

Stochastic Properties

For a trustworthy least-squares (LS) solution, a good description of the stochastic properties of the measurements is indispensable. For a terrestrial laser scanner (TLS), the range variance can be described by a power law function with respect to the intensity of the reflected signal. The power and scaling factors depend on the laser scanner under consideration, and could be accurately determined by means of calibrations in 1d mode or residual analysis of LS adjustment. However, such procedures complicate significantly the use of empirical intensity models (IM). The extent to which a point-wise weighting is suitable when the derived variance covariance matrix (VCM) is further used in a LS adjustment remains moreover questionable. Thanks to closed loop simulations, where both the true geometry and stochastic model are under control, we investigate how variations of the parameters of the IM affect the results of a LS adjustment. As a case study, we consider the determination of the Cartesian coordinates of the control points (CP) from a B-splines curve. We show that a constant variance can be assessed to all the points of an object having homogeneous properties, without affecting the a posteriori variance factor or the loss of efficiency of the LS solution. The results from a real case scenario highlight that the conclusions of the simulations stay valid even for more challenging geometries. A procedure to determine the range variance is proposed to simplify the computation of the VCM.

Batik, which is rich in symbols and philosophies for the Indonesian people, has now been recognized by UNESCO as a Representative List of the Intangible Cultural Heritage of Humanity. The beginning of the emergence of batik in Indonesia is in the city of Solo, and comes from the Pajang kingdom 400 years ago. With the passage of time, batik continues to grow and produces various variations and innovations, from raw materials to the drawn motifs. However, it is very unfortunate that not all of the previous heritage batik can be maintained. Recently, there has been a batik museum created by individuals or institutions, but in the design, some interior elements are less than optimal in their arrangement. So they don't affect the batik stored or on display. In this research, focus of the discussion is on standardization which discusses spatial planning, facilities, collections, lighting, ventilation, acoustics and museum security, which are combined with local wisdom of Surakarta architecture, so that the data becomes a batik museum with character and can preserve the stored batik. This research uses a case study of the Surakarta batik museum, and the final results of this study can be used as a guide for designing a museum with fabric materials in it.

AbstractThree hundred sixty–degree (360°) immersive video applications for Head Mounted Display (HMD) devices offer great potential in providing engaging forms of experiential media solutions especially in Cultural Heritage education. Design challenges emerge though by this new kind of immersive media due to the 2D form of resources used for their construction, the lack of depth, the limited interaction and the need to address the sense of presence. In addition, the use of Virtual Reality (VR) headsets often causes nausea, or motion sickness effects imposing further implications in moderate motion design tasks. This paper introduces a methodological categorisation of tasks and techniques for the design of 360° immersive video applications. Following the design approach presented, a testbed application has been created as an immersive interactive virtual tour at the historical centre of the city of Rethymno in Crete, Greece, which has undergone user trials. Based on the analysis of the results of this study, a set of design guidelines for the implementation of 360° immersive video virtual tours is proposed.

Conservation And Management

The aim of this article is to provide a dedicated approach to the realisation of a CityGML model for the valorisation and the conservation of existing cultural heritage. In particular, for the ancient city of Taranto (Italy), several levels of details (LODs) have been built. CityGML models in LOD1 for the most representative periods were realised, which were characterised by urban changes from the mid-1800s until today. To achieve this aim, great importance was devoted to the process of integration of the different file formats. A geographic information system (GIS) approach has been put in place for the construction of the CityGML model in LOD1. In addition, the study also focused on the realisation of a CityGML model in LOD3 of a bridge of a particular historical and architectural interest, called “Ponte di Porta Napoli”, also situated in the city of Taranto. In the latter case, the CityGML model was realised starting from the geomatics survey. Therefore, the project structured in this way represents an important tool for the sharing of (georeferenced) territorial information. The CityGML models represent a valid support for spatial planning processes and measures for the protection, monitoring and conservation of urban elements.

The Town

The research activities described in this contribution were carried out at San Leo (Italy). The town is located on the top of a quadrangular rock slab affected by a complex system of fractures and has a wealth of cultural heritage, as evidenced by the UNESCO’s nomination.<br><br> The management of this fragile set requires a comprehensive system of geometrical information to analyse and preserve all the geological and cultural features. In this perspective, the latest Geomatics techniques were used to perform some detailed surveys and to manage the great amount of acquired geometrical knowledge of both natural (the cliff) and historical heritage. All the data were also georeferenced in a unique reference system.<br><br> In particular, high accurate terrestrial laser scanner surveys were performed for the whole cliff, in order to obtain a dense point cloud useful for a large number of geological studies, among others the analyses of the last rockslide by comparing pre- and post-event data.<br><br> Moreover, the geometrical representation of the historical centre was performed using different approaches, in order to generate an accurate DTM and DSM of the site. For these purposes, a large scale numerical map was used, integrating the data with GNSS and laser surveys of the area.<br><br> Finally, many surveys were performed with different approaches on some of the most relevant monuments of the town. In fact, these surveys were performed by terrestrial laser scanner, light structured scanner and photogrammetry, the last mainly applied with the Structure from Motion approach.

The paper describes the implementation of the 3D city model of the pedestrian area of Cosenza, which in recent years has become the Bilotti Open Air Museum (MAB). For this purpose were used both the data available (regional technical map, city maps, orthophotos) and acquired through several surveys of buildings and "Corso Mazzini" street (photos, topographic measurements, laser scanner point clouds). In addition to the urban scale model, the survey of the statues of the MAB was carried out. By means of data processing, the models of the same statues have been created, that can be used as objects within the city model. <br><br> The 3D model of the MAB open air museum has been used to implement a Web-GIS allowing the citizen's participation, understanding and suggestions. The 3D city model is intended as a new tool for urban planning, therefore it has been used both for representing the current situation of the MAB and for design purposes, by acknowledging suggestions regarding a possible different location of the statues and a new way to enjoy the museum.
