3D LiDAR and Photogrammetry Scans of Kim Shin Lane, Cheung Sha Wan, Hong Kong
Description
This dataset includes 12 point cloud files from combined photogrammetric and LiDAR scans, text descriptions, registration files, and field photographs of the Kim Shin Lane complex in Cheung Sha Wan, Hong Kong. Records date from late 2024 to early 2025. 3D scan files and field photographs are separated into compressed folders (.zip) and separated by the dates of collection given in the file names. 3D scan data collection entailed single, approximately 10-minute walkthroughs of parts of the Kim Shin Lane complex, including interior and exterior conditions, with the Leica-brand BLK2GO model 3D environment scanner. Each scan describes the architecture of Kim Shin Lane in high detail and color. Scans have been decimated to a voxel size of 5 mm to reduce file size. The data provide clear enough rendering of the physical conditions of the building to allow interpretation of the building's physical condition. Calendar dates for when material was collected are given in file names in day.month.year format (e.g., 11.3.25 means the material was gathered on March 11, 2025). Each scan describes a different part of the Kim Shin Lane complex. Each compressed folder includes a text description file (.txt) describing the content of the 3D scans, and registration files giving an overview of each point cloud file are also included in the compressed folders. Content of each 3D scanning collection is also given here in summary: Elkin_KSL_13.12.24_3Dscans.zip: 2 3d scans of interiors of one of the Kim Shin Lane buildings showing multiple sub-divided flat apartments. Elkin_KSL_11.3.25_3Dscans.zip: 3 3d scans of exterior conditions at Kim Shin Lane. 2 scans show the lane between the buildings. 1 scan shows a rooftop of one of the buildings. Elkin_KSL_28.3.25_3Dscans.zip: 7 3d scans mostly of interior conditions at Kim Shin Lane. These scans show mostly interior stairwells that connected the corridors in the Kim Shin Lane buildings and 1 shop space in the ground floor of the complex. The data is available immediately. Scan files, text, and photographs are provided for purposes of digital conservation and for interpretation of physical conditions through further research. More detailed information on the dataset is available upon reviewed request. The architecture shown in this dataset is being or was demolished as part of the site area in the Hong Kong Urban Renewal Authority (URA) scheme SSP-017. They, therefore, will no longer be able to be physically reproduced as the architecture shown no longer exists as of mid to late 2025. The Kim Shin Lane complex consisted of two modified Chinese shop house (Tong Lau) buildings with continuous corridors running through the interiors and with staircases connecting through the buildings to a lane between them and to surrounding streets.

Steps to reproduce
The data in this dataset cannot be reproduced, since the physical conditions documented have been or will be demolished. Residents living in Kim Shin Lane were relocated from the area and the buildings demolished throughout early and mid 2025. Similar datasets can be produced using the Leica BLK2GO LiDAR and photogrammetry scanner or similar 3D environment scanning equipment.
