Digital Deforestation: Comparing Automated Approaches to the Production of Digital Terrain Models (DTMs) in Agisoft Metashape

This paper tests the suitability of automated point cloud classification tools provided by the popular image-based modeling (IBM) software package Agisoft Metashape for the generation of digital terrain models (DTMs) at moderately-vegetated archaeological sites. DTMs are often required for various forms of archaeological mapping and analysis. The suite of tools provided by Agisoft are relatively user-friendly as compared to many point cloud classification algorithms and do not require the use of additional software. Based on a case study from the Mycenaean site of Kastrouli, Greece, the mostly-automated, geometric classification tool “Classify Ground Points” provides the best results and produces a quality DTM that is sufficient for mapping and analysis. Each of the methods tested in this paper can likely be improved through manual editing of point cloud classification.

NEW RADIOCARBON DATES FROM ARCHAEOLOGICAL SITES IN PARTS OF IGBOLAND, SOUTHEASTERN NIGERIA

ABSTRACT This paper presents new results of radiocarbon (14C) ages from archaeological sites in northern Igboland. The study was designed to shed more light on early human occupation and activities in the study area based on sediments from cave and iron-smelting sites. The approach consisted of ethnographic, archaeological, palynological, and slag analyses; these were complemented with 14C dates. The technology adopted as well as the paleoenvironmental conditions that prevailed during the period of human settlement in both sites was revealed. These data, complemented by 14C dates, highlight the human behavioral and subsistence patterns within the region and are comparable to those from similar sites in southeastern Nigeria.

Public Law Restrictions in the Context of 3D Land Administration—Review on Legal and Technical Approaches

Intense exploitation of land implies the development of multi-level, multi-purpose, overlapping and interlocking structures on 3D space, thus resulting in complex, stratified, 3D real property rights between individual owners, as well as restrictions. Legislation regulates the ownership status and use of land by imposing restrictions known as Public Law Restrictions (PLRs). PLRs extend to various fields and various legislative frameworks, such as the protection of archaeological sites, protection and maintenance of underground infrastructures and utilities, environmental protection, flying of unmanned air vehicles, etc. PLRs are usually investigated in the context of property rights and restrictions in the various Land Administration Systems worldwide, and do not often gain specific attention. However, it is noticed that the restrictions that arise from Public Law need to be investigated and classified, so that they can be better utilised in the property status of land ownership. This review paper investigates the legal statutes on PLRs within the context of 3D land administration and the stipulations used to provide unambiguous modelling of PLRs, as provided by the relative literature. Moreover, the PLRs applied in the 3D space, to clearly depict rights, restrictions and responsibilities on the relevant spatial unit (land, air, marine parcel, mine, utility network, etc.), are particularly examined. Therefore, this work is to critically review and assess the aforementioned approaches on PLRs’ registration, modelling and organisation, as provided by a literature survey, and provides an overall view of the requirements and challenges within the development of 3D Land Administration Systems also considering standardisation developments.

Evolution of fluvial environments and history of human settlements on the Ticino river alluvial plain

The present contribution aims to provide better knowledge on the evolution of the fluvial environments of the Ticino river alluvial plain, highlighting the complex interaction of the Ticino river and its lateral tributaries with the human communities since the Neolithic. The study considers information derived from historical sources, from previous research on three sites based in the Ticino river floodplain and from data of six archaeological sites located on four alluvial fans. For the investigated sites the analyses of the lithostratigraphy and the archaeological evidence were constrained with radiocarbon dating, providing the interpretation of the depositional context of the studied sequences and their correlation with the cultural periods and epochs defined for the southern Swiss Alps. The combined approach allowed for the definition of 13 phases of enhanced hydro-sedimentary activity from the Neolithic to the contemporary period. The possible palaeoenvironmental and palaeoclimatic causes, as well as the impacts of these phases on the human settlements, are discussed.

Sustainability of Cultural Heritage in Inland Territories

This chapter researches the possibilities for the sustainability of cultural heritage in inland territories, focusing on the case study of two archaeological sites in Serbia. Two plans, the plan for the archaeological site of Gamzigrad-Romuliana and the plan for the archaeological site of Caričin grad (Justiniana Prima), were analyzed from the aspect of sustainable development. These plans were prepared in compliance with the principles of preservation, protection, revitalization, and use of immovable cultural property for the purposes of science, education, presentation to the public and tourism. The conflicts between cultural heritage protection and development of tourism were analyzed. As a result of the analysis, recommendations for the sustainability of cultural heritage in inland territories are given in the chapter.

Alexandria Antiqua: A Topographical Catalogue and Reconstruction

This book is an attempt to find a way through an archaeological labyrinth of fragmentary evidence. Taking into account the last two centuries of systematic research into the topography of the ancient city while integrating the latest discoveries, the volume aims to catalogue the archaeological sites of Alexandria, from the records of the French Expedition (1798-99) to the present day, and to infer the urban layout and cityscape at the time of its foundation (4th century BC), and then through the successive changes which took place up to the Arab conquest in the 7th century AD. To this end, a holistic approach to topographic reconstruction is adopted, where material culture is studied in conjunction with the historical record. The results are displayed in AutoCAD maps and over 340 illustrations.

Comparativa de características de software para la creación de recorridos virtuales 360 en Web

The use of 360 virtual tours has become a technology that allows viewing from different angles, places, or spaces that, due to various circumstances, it is not possible to visit physically. Due to different restrictions existing today; of a physical, economic or health type, virtual visits to museums, archaeological sites, parks, and facilities of various kinds have become an alternative to disseminate, promote, or bring users closer to places, that through 360 panoramic images, make them feel immersed in them. Currently, creating a 360 virtual tour is available to more people, as the software and hardware tools used are increasingly accessible. However, deciding on the most appropriate software platform to publish virtual tours on the web can be a trial-and-error process, delaying obtaining these virtual products.
