The Acero Estudio team in Peru carried out the geodesy work, drone flight and restitution of the area planned for Pedestrian Accessibility to and from the Metropolitan Stations, Lima.
Given the current global pandemic situation due to COVID-19, these tasks were all carried out under preventive measures and medical examinations.
To better understand the work carried out by our team in the project area, they began with the placement of Geodetic Points (one at each station) linked to the IGN coordinate system. Their measurement using dual-frequency differential GPS. Next, the necessary support points were located for the subsequent restoration of the drone flight. These support points were marked with an X-shaped template and paint, and measured with GPS in RTK mode.
The drone flight of the 33 stations was carried out at an appropriate height taking into account the height of the existing buildings and elements. For this, a DJI Phantom 4 Pro drone with a 20 Mpx camera was used. Once the photogrammetric images were obtained, they were processed and the point cloud and orthophoto of each station was created. With the orthophoto and the point cloud, the MDT was processed and subsequently the restitution of the environment of each station.
We thank our client CPS for all the trust placed in our team and the work of coordinating and directing the work carried out.
Remember that at Acero Estudio we are specialists in photogrammetry services with drones and LIDAR, both services performed with drones and very useful for engineering or architectural projects.
