In 2024, the EPC team carried out a laser scanner drone survey for the municipality of San Vito di Cadore (BL), at the former aggregate landfill called \u201cLa Vallesella.\u201d The site, located on the hydrographic left of the Boite Valley on the southern slopes of Mount Sorapis, has been the subject of several monitoring campaigns since 2011.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The main objective of our intervention was to verify any morphological changes at the site from previous surveys and to provide high quality data to represent the state of affairs. Specifically, the survey resulted in<\/p>\n

    For the survey of ‘La Vallesella<\/strong>‘, we chose the DJI Zenmuse L1<\/strong>, DJI’s first LiDAR instrument for the Matrice 300 RTK<\/strong>.<\/p>\n

    The Matrice 300 RTK is a powerful industrial aerial platform equipped with an advanced flight control system, a six-way tracking and positioning system and an FPV camera. Correct georeferencing of the collected data was ensured by the built-in RTK module, which provided accurate position data.<\/p>\n

    The Zenmuse L1<\/strong> payload includes a LiDAR module, a high-precision IMU<\/strong>, and a camera with a 20 MP CMOS sensor<\/strong>. Combined with the Matrix 300 RTK and DJI Terra software, it is a complete solution that provides real-time 3D data<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    The survey was carried out according to a carefully prepared preliminary plan<\/strong> based on the morphological characteristics of the terrain<\/strong>. The operations followed a rectilinear flight pattern, with periodic calibrations to optimize data accuracy<\/strong>. The Matrice 300 RTK performs calibrations at the beginning and end of each flight mission, at the midpoint of any flight segment longer than 1,000 meters, and every 100 seconds during extended flights to ensure optimal accuracy in overlapping areas.<\/p>\n

    The georeferencing<\/strong> was refined by using a GPS antenna, which improved the accuracy of the point clouds.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
