A trigonometric and polygonometric network was established using Spectra GNSS receivers and a Leica 1” Total station, with the total station a partial survey was accomplished. Using the DJI UAV Phantom 4 RTK, aerial photographs were captured in the form of a grid in a low altitude, achieving spatial analysis and accuracy of ≈1cm.
Using a Faro laser scanner, a three-dimensional scan of the entire monument was performed. Through the above images, a point cloud with real texture was produced, with a resolution and accuracy of only a few millimeters. In addition, a triangle mesh, a topographic diagram and a large-scale plan view were produced.
Finally, through ground and aerial photos as well as 360°, a virtual tour of the monument was carried out, so that any remote visitor can tour the site and receive all the necessary information about the monument.
