Geomatics engineering and drone technology have come together in a pioneering project in southern Gran Canaria. Digital Fibers Planners SL recently completed the photogrammetric survey of the Corallium Beach Hotel by Lopesan, a precision project that allowed them to rigorously document every detail of its facades without disrupting the surrounding tourist activity.
The project, carried out on Los Jazmines Street in San Agustín, combined flights with drones equipped with high-resolution RGB cameras and GNSS receivers with RTK technology. This methodology guaranteed highly reliable georeferencing, with a margin of error of less than three centimeters.
The work was supported by the meticulous establishment of ground control points connected to the permanent Maspalomas antenna. From there, photogrammetric flights were planned with longitudinal and lateral overlap, generating complete coverage of the building. The images were subsequently processed using specialized software to create a georeferenced point cloud and digital elevations organized by facades, interior courtyards, and entrances.
The results achieved an exceptional level of detail. The total area of the hotel complex's facades was calculated at 5.884,53 square meters, with an uncertainty of just 8,42 millimeters in the GNSS readings. Subsequent corrections in AutoCAD consolidated a reliable model, suitable for future renovations or technical inspections.
The use of cutting-edge drones, such as the DJI Air 3S, along with Topcon HiPer SR GNSS receivers, enabled not only metric accuracy but also operational safety in an urban and tourist environment. The experience became a clear example of how cutting-edge technology applied to surveying can optimize costs, time, and quality in civil engineering and architectural projects.
With this survey, Digital Fibers Planners strengthens its position in the Canary Islands as a company specializing in advanced geomatics and topography solutions. The company emphasizes that this type of work opens the door to new applications in urban rehabilitation, architectural planning, and hotel infrastructure management, key sectors for the archipelago's economic development.
