I find this UAV capture so cool. The statue was designed in the 1920s, and the location of the statue — on top of the 700-meter Corcovado Mountain in Brazil’s second largest city, Rio de Janeiro — has made it too challenging for modern methods such as LIDAR

Data was collected over a series of 19 ten-minute flights with 2,090 separate images stitched together to create the final 3D model. This now exists as both a wireframe mesh made up of 2.5 million triangles and a point cloud composed of 134.4 million individual points — more than enough for an accurate record of the statue.
