“…By measuring the vegetative cover, and penetrating up to the ground, information is obtained on the altitudes with a centimetric accuracy. Many examples of LiDAR applications can be examined, for instance, from the punctual morphology representation of hydrogeological hazard areas, to the urban and infrastructure modeling and planning, to the design of power and energy distribution lines, and inventory and management of forests [9][10][11][12][13]. Moreover, the combination of LiDAR information with data from other sources can greatly help in improving the features' extraction and classification for Earth Monitoring and Remote Sensing as highlighted in [20] and discussed later in this paper.…”

“…An extensive additional list of references, highlighting the main LiDAR characteristics, its advantages and disadvantages, and the different fields of applications with several case studies, can be found in [9][10][11][12][13], showing how LiDAR has contributed significantly in the EO and Remote Sensing fields. The above references can be regarded as useful guidelines for researchers interested in using LiDARs.…”

The aim of this paper is to highlight how the employment of Light Detection and Ranging (LiDAR) technique can enhance greatly the performance and reliability of many monitoring systems applied to the Earth Observation (EO) and Environmental Monitoring. A short presentation of LiDAR systems, underlying their peculiarities, is first given. References to some review papers are highlighted, as they can be regarded as useful guidelines for researchers interested in using LiDARs. Two case studies are then presented and discussed, based on the use of 2D and 3D LiDAR data. Some considerations are done on the performance achieved through the use of LiDAR data combined with data from other sources. The case studies show how the LiDAR-based systems, combined with optical Very High Resolution (VHR) data, succeed in improving the analysis and monitoring of specific areas of interest, specifically how LiDAR data help in exploring external environment and extracting building features from urban areas. Moreover the discussed Case Studies demonstrate that the use of the LiDAR data, even with a low density of points, allows the development of an automatic procedure for accurate building features extraction, through object-oriented classification techniques, therefore by underlying the importance that even simple LiDAR-based systems play in EO and Environmental Monitoring.

“…A detailed visual representation was proven to be requisite to achieve a connection to reality to increase comprehension. Light detection and ranging (LiDAR) has been applied to 3D scan technology to document as-built scenes for construction monitoring [ 43 , 44 , 45 ] or to retrieve geometric features from a distance with a combination of aerial images [ 46 , 47 , 48 , 49 , 50 , 51 ]. In contrast to creating 3D models from the beginning, 3D laser scanning is an effective tool for acquiring important geometric attributes, such as detailed trees and vegetation [ 52 ].…”

Zoning conflicts have transformed Old Street fabrics in terms of architectural style and construction material in Lukang, Taiwan. This transformation should be assessed as a contribution to digital cultural sustainability. The objective of this study was to compare the evolved façades resultant from the changes made by the development of architectural history and urban planning. A combination of 3D scan technology and a smartphone augmented reality (AR) app, Augment®, was applied to the situated comparison with direct interaction on-site. The AR application compared 20 façades in the laboratory and 18 façades in four different sites using a flexible interface. The comparisons identified the correlation of evolved façades in real sites in terms of building volumes and components, pedestrian arcades on store fronts, and previous installations. The situated comparisons were facilitated in a field study with real-time adjustments to 3D models and analyses of correlations across details and components. The application of AR was demonstrated to be effective in reinstalling scenes and differentiating diversified compositions of vocabulary in a remote site.
