“…Historical heritage and cultural landscapes were often digitally reconstructed by integrating RS and GIS data [29]. LiDAR studies have been conducted to reconstruct a city [30], inspect physical cultural heritage [31], and simulate a real environment in augmented reality (AR) [32][33][34][35]. RS images can be integrated with LiDAR data to improve geo-positioning accuracy in metropolitan areas [36,37].…”

Old urban reform usually reactivates the urban fabric in a new era of sustainable development. However, what remains of the former fabric and how it interacts with the new one often inspires curiosity. How the old residents adapt their lives to the new layout should be explored qualitatively and quantitatively. This research aimed to assess the old and new fabrics in the downtown area of Keelung, Taiwan, by considering the interactions between truncated layout, proportion, and infill orientation in the mature and immature interfaces. According to the historical reform map made in 1907, the newly constructed area occupied the old constructed area in seven downtown blocks. On average, the area composed of new buildings ranged from 135.60% to 239.20% of the old area, and the average volume of the buildings reached a maximum of 41.72 m when compared to the old buildings in place prior to the reform. It seems that the new fabric purposefully maintained the old temples at the centers of the blocks. However, the old alleys, which still remain within these blocks, have been significantly overloaded with services and have become auxiliary utility spaces for the in-block residences. With regard to the part of the fabric that was truncated or reoriented by new streets, the modification could also be easily found on the second skin. A physical model analysis used a UAV 3D cloud model and QGIS® to verify the axes, hierarchies, entrances, open spaces, and corners in the commission store block and temple blocks. We found that the 3D point model and historical maps presented a convincing explanation of the evolved fabric from the past to the present. The stepwise segmentation visualizes the enclosed block inside a block on the historical maps and according to the present sections. We found that new roles for old alleys have evolved behind the new fabric.

“…Remote sensing and geographic information system (GIS) data are usually integrated [24]. Light detection and ranging (LiDAR) studies have been conducted for city reconstruction [25], physical-cultural heritage [26], and AR applications [27][28][29] in real environments. Remote sensing imagery can be integrated with LiDAR data to improve geopositioning accuracy in metropolitan areas [30].…”

The Taiwan Lantern Festival (TLF) is a specific cultural tradition that has evolved over many years. It is a large-scale festival as determined by the large number of installations and visitors—that is, 20 million visitors in a period of two weeks. The aim of this study is to combine the TLF-related physical dynamics of land use and lantern installations with the augmented dynamics of lantern installations at reallocated sites. We compared five cities in Taiwan with regard to land alterations between 2016 and 2020. The TLF land assessment identified 34 cross-referred types of land use between aerial imagery and GIS surveys in a small area of 2 km × 2 km, in total. The change in land use by year varied between 2% and 499%, up to three times. The complexity of physical dynamics was re-experienced by a more sustainable dynamic of augmented reality (AR) using a scan-to-AR approach to reactivate the installations and fabrics at redeployed sites. The installations of the 2016 TLF were applied. We found that the land use, 3D scan, and AR reshaped the spatio-temporal festivalscape by both types of dynamics. The simulation demonstrated that the fabric retrieved by heterogeneous technologies had equal importance in assessing the host city and in enabling a reactivation for more diversified scales and characters, even with a smartphone AR.

A lantern festival was 3D-scanned to elucidate its unique complexity and cultural identity in terms of Intangible Cultural Heritage (ICH). Three augmented reality (AR) instancing scenarios were applied to the converted scanned data from an interaction to the entire site; a forward additive instancing and interactions with a pre-defined model layout. The novelty and contributions of this study are three-fold: documentation, development of an AR app for situated tasks, and AR verification. We presented ready-made and customized smartphone apps for AR verification to extend the model’s elaboration of different site contexts. Both were applied to assess their feasibility in the restructuring and management of the scene. The apps were implemented under a homogeneous and heterogeneous combination of contexts, originating from an as-built event description to a remote site as a sustainable cultural effort. A second reconstruction of screenshots in an AR loop process of interaction, reconstruction, and confirmation verification was also made to study the manipulated result in 3D prints.
