“…Range scanning has also been put into practice through a wide range of devices and methods capable of performing positional mapping, with proven benefits for archeology. For example, satellite-based radio detection and ranging (radar) technology was previously used to map ruins of the Maya civilization with interesting results, even in forested areas [47]. Another widely-known sensing method is LIDAR, which has been used not only for terrain's digital modeling, enabling the detection of archeological ruins [48], but also for digital reconstruction purposes [49].…”

Virtual models’ production is of high pertinence in research and business fields such as architecture, archeology, or video games, whose requirements might range between expeditious virtual building generation for extensively populating computer-based synthesized environments and hypothesis testing through digital reconstructions. There are some known approaches to achieve the production/reconstruction of virtual models, namely digital settlements and buildings. Manual modeling requires highly-skilled manpower and a considerable amount of time to achieve the desired digital contents, in a process composed by many stages that are typically repeated over time. Both image-based and range scanning approaches are more suitable for digital preservation of well-conserved structures. However, they usually require trained human resources to prepare field operations and manipulate expensive equipment (e.g., 3D scanners) and advanced software tools (e.g., photogrammetric applications). To tackle the issues presented by previous approaches, a class of cost-effective, efficient, and scarce-data-tolerant techniques/methods, known as procedural modeling, has been developed aiming at the semi- or fully-automatic production of virtual environments composed of hollow buildings exclusively represented by outer façades or traversable buildings with interiors, either for expeditious generation or reconstruction. Despite the many achievements of the existing procedural modeling approaches, the production of virtual buildings with both interiors and exteriors composed by non-rectangular shapes (convex or concave n-gons) at the floor-plan level is still seldomly addressed. Therefore, a methodology (and respective system) capable of semi-automatically producing ontology-based traversable buildings composed of arbitrarily-shaped floor-plans has been proposed and continuously developed, and is under analysis in this paper, along with its contributions towards the accomplishment of other virtual reality (VR) and augmented reality (AR) projects/works oriented to digital applications for cultural heritage. Recent roof production-related enhancements resorting to the well-established straight skeleton approach are also addressed, as well as forthcoming challenges. The aim is to consolidate this procedural modeling methodology as a valuable computer graphics work and discuss its future directions.

4This paper provides an overview of the opportunities that image analysts, archaeologists and conservation 5 scientists currently have of using space-borne Synthetic Aperture Radar (SAR) imagery for prospection of 6 cultural landscapes and investigation of environmental, land surface and anthropogenic processes that can alter 7 the condition of heritage assets. The benefits of the recent developments in SAR satellite sensors towards higher 8 resolution (up to less than 1 metre) and shorter revisiting times (up to a few days) are discussed in relation to 9 established techniques using the two key SAR parameters -amplitude and phase. Selected case studies from 10 Middle East to South America illustrate how SAR can be effectively used to detect subtle archaeological 11 features in modern landscapes, monitor historic sites and assess damage in areas of conflict. These examples 12 form the basis to highlight the current trends in archaeological remote sensing based on space-borne SAR data 13 in the current era of the European Space Agency's Sentinel-1 constellation and on-demand high resolution space 14 missions. 15
