Abstract The archaeological site of the Domus Romana in Rabat, Malta was excavated almost 100 years ago yielding artefacts from the various phases of the site. The Melite Civitas Romana project was designed to investigate the domus, which may have been the home of a Roman Senator, and its many phases of use. Pending planned archaeological excavations designed to investigate the various phases of the site, a team from the Institute for Digital Exploration from the University of South Florida carried out a digitization campaign in the summer of 2019 using terrestrial laser scanning and aerial digital photogrammetry to document the current state of the site to provide a baseline of documentation and plan the coming excavations. In parallel, structured light scanning and photogrammetry were used to digitize 128 artefacts in the museum of the Domus Romana to aid in off-site research and create a virtual museum platform for global dissemination.

The survey of archaeological sites by appropriate geomatics technologies is an important research topic. In particular, the 3D survey by terrestrial laser scanning has become a common practice for 3D archaeological data collection. Even if terrestrial laser scanning survey is quite well established, due to the complexity of the most archaeological contexts, many issues can arise and make the survey more difficult.<br> The aim of this work is to describe the methodology chosen for a terrestrial laser scanning survey in a complex archaeological environment according to the issues related to the particular structure of the site. The developed approach was used for the terrestrial laser scanning survey and documentation of a part of the archaeological site of Elaiussa Sebaste in Turkey. The proposed technical solutions have allowed providing an accurate and detailed 3D dataset of the study area. In addition, further products useful for archaeological analysis were also obtained from the 3D dataset of the study area.

As a result of the technological development, remote sensing instruments and methods have become widespread in all segments of life (from precision agriculture through architecture to medicine). Among the innovative development of remote sensing instruments the 3D laser scanner is overriding importance. The horticulture applicability of terrestrial laser scanning technique is innovation in the precision agriculture, because it could be determine the structure of trees and branches, the canopy extension, which can help to recognize some biophysical parameters. The examination was carried out with Leica ScanStation C10 terrestrial laser scanner in the Study and Regional Research Farm of the University of Debrecen near Pallag. In this article I present the measuring principle, the parameters and horticulture applicability of the terrestrial laser scanner.

<p><strong>Abstract.</strong> Generally, terrestrial laser scanning surveys involve a rather large number of scans to ensure a high percentage of overlap required for the scan registration phase (target-based or point-based registration, cloud-to-cloud registration). These approaches result in data redundancy that could slow down both the acquisition and post-processing phases. In recent years, the technological evolution in the field of laser scanners has been directed to the development of devices that are able to perform an onsite pre-registration, to optimize the survey procedures and the reliability of the registration of the scan. The paper presents the results achieved during a terrestrial laser scanning survey carried out for the documentation and 3D reconstruction of the large and complex archaeological remains of the so-called Roman <i>Domus</i> in the archaeological site of <i>Lylibaeum</i> (Marsala, Italy). The survey was also conducted using a terrestrial laser scanner capable of pre-registering scans using a topographic approach. The pre-registration procedure and the data acquisition strategy have allowed to optimize the workflow and to obtain a 3D model of the Roman <i>Domus</i> with a high level of detail and area coverage.</p>

Abstract. This paper describes a feasibility study for the digitisation of gravestones, specifically Jewish gravestones, alongside an implementation of Multi-Criteria Decision Making. MCDM methods are common in other contexts, and have been used to address issues particular to design, organisation and management of large-scale construction and engineering projects. They are, however, novel in the context of cultural heritage. This paper will examine the potentials of non-contact sensor technologies (including photogrammetry via Structure from Motion, structured light scanning and terrestrial laser scanning) to record, model and archive the stones and their inscriptions. The various methodologies will be assessed against set criteria, specifically speed, resolution, readability and scalability for mass recording, from MCDM including criteria given by humanities scholars in the field of history, theology and Jewish studies.

Abstract. The course "Geoscience Field Issues Using High-Resolution Topography to Understand Earth Surface Processes" was originally intended to be conducted in-person with both field data collection and analysis to meet the "field" component of the University of Northern Colorado's Earth Science degrees (Environmental and Geology). With the 2020 world pandemic and cancellation of most in-person activities for 2020, the course was adapted for 100 % online implementation with an optional one-day field campaign. To prepare for the changed delivery model, UNAVCO and the University of Northern Colorado collected GNSS data, drone imagery for use in structure from motion, and terrestrial laser scanning from a site near Greeley, Colorado USA on the Cache la Poudre River. These data were used in mock field campaigns and real analyses implemented by students virtually through Zoom and Canvas. The objective of the course is to train students in manual and remote sensing methods of topographic data collection, including 1) GPS/GNSS surveys, 2) structure from motion (SfM), and 3) ground-based (terrestrial laser scanning, TLS) and airborne LiDAR. Course content focused on earth-surface process applications, but could be adapted to other applications. This was taught workshop style with the bulk of the instruction and application occurring within a 2-week period during the summer. Students from throughout North America attended the course, most meeting Field Camp requirements required for graduation. Despite the challenging conditions, students met the majority of the National Association of Geoscience Teachers’ Field Capstone Learning Outcomes.

The Monuments Board of the Slovak Republic (MB SR) and the Regional Monuments Boards have been the state administrators of the cultural heritage, including archaeology, since 2002. This article aims to map the current state of archaeological digital archives within MB SR and eight Regional Monuments Boards, as well as present the usage and management of digital datasets within ongoing projects. The central archive of the MB SR maintains historical plans and cultural heritage documentation, created since the 1920s and continuously digitised (the collections of negatives, diapositives, projects, plans, schematic maps, and fieldwork documentation). Since 2012, MB SR has taken part in the Digital Monuments Fund project. Within this project, 2D and 3D documentation of a great number of cultural monuments has been created. In 2019 the implementation phase of the Monuments information system (PAMIS) project started. Its basic modules are the presentation layer, the knowledge agenda and state administration. There are several features in preparation within these modules, such as: updating; collection, consolidation and GIS processing of archaeological site data that belong to the monuments fund, including data from aerial laser scanning; the archaeological excavation registry and the archive of fieldwork reports; the registry of finds in the administration of MB SR; the electronic processing of the state administration activity within the protection of the archaeological cultural heritage. The PAMIS project will provide processed data and make them accessible to the state and public administration, owners of monuments, as well as to professionals and the general public, using online solutions (web GIS) with various approaches according to defined user roles.
