3.2 OVERVIEW SINGLE SCANS

The faro Lidar Focus S350 scanner was used to survey the area. The focus of the data acquisition was the northern part of the area, especially the section of Vincent Terrace between the Islington Tunnel and Frog Lane Bridge and the area around the locks that regulate the water level of the canal. The survey was carried out in a circular clockwise direction around the area. A total of 17 scans were carried out. The instrument was set up as follows:

Profile: Outdoor

Resolution: ¼

Quality: 3x

The area was surveyed on 18 April 2023. The settings of the device were made due to the cloudy weather and the large distances of the area. Risks considered when planning the survey included the likelihood of rain, the proximity to the water without parapet protection and the increased frequency of pedestrians and cyclists on the narrow paths along the canal. Some buildings along the canal and the basin are not accessible to the public and could therefore not be surveyed in detail.

To process the data, Faro Scene was used in the first step to process, register and align the scans. Then they were exported and processed in Cloud Compare and Bentley Pointtools vI8. Finally, the results were edited in Adobe Photoshop and Premiere pro and merged with the archive material.
