CASE STUDY HIGH MOUNTAIN TOPOGRAPHY The “Order of Expert Surveyors” is a professional institution that was founded in 1946. Under the supervision of the Department of Urban Development, its purpose is to enforce legislation governing the profession and to supervise the activities of the professionals of the industry. THE CLIENT′S NEED This operation has been ordered by the Order of Expert Surveyors. They needed to provide a new measure of this French emblematic mountain and wanted to promote the use of drones to map large and complex areas. This measurement and modeling exercise has been set up with the support of many partners: the Pyrénées-Atlantiques departmental chamber of the National Union of Surveyors (UNGE), Aeromapper (Long range UAV manufacturer), Géomesure (Trimble distributor), Teria network (real time centimeter geolocation network). The modeling was conducted in conjunction with Covadis, a topography software published by Geomedia. THE SOLUTION Aeromapper is the manufacturer of the AVEM, a long-range UAV certified for BVLOS operations dedicated to high resolution mapping of large areas. Equipped with a 24MPx RGB sensor, the AVEM has up to 3h of endurance which is perfectly suited to this kind of operation. However, collecting data at an elevation of more than 3000m over mountainous terrain is no easy task: strong winds, clouds, turbulences, obstacles, ... were some of the challenges to take up! The AVEM did it perfectly. Aeromapper | 33, Rue de la Bièvre - 92340 - Bourg-la-Reine - FRANCE | Tel : +33 1 84 17 26 09 www.aeromapper.com | contact@aero

Early wake up for the 50 people involved in the operation. After a hearty breakfast, our team went on a hike to the first takeoff site. By noon, the AVEM was launched and started collecting data. Despite wind and turbulences, the UAV flew perfectly its flight plans. Thanks to a thorough preliminary landing sites check, the AVEM came back to a landing without difficulty. The crew then moved on to a 2nd operation site to cover the west side of the peak. In 2 days, 5 flights were performed which represents a total of 4305 high resolution pictures with precise POS.
