Mapping the Unseen: A Case Study in the Integration of Photogrammetry, LiDAR, and Geomagnetic Data to Better Characterize a Closed Landfill
LiDAR and photogrammetry surveys as well as the broad array of infrared sensing methods using unmanned aircraft systems (sUAS) are focused on what is happening on the surface of the earth. A highly sensitive geoscientific grade magnetometer is capable of mapping ferromagnetic objects and rock formation that buried below the surface of the earth. The integration of these multivariate data volumes is a revolution in truly 3D information content, not just 3D surface mapping. We will present a case study that integrates LiDAR, photogrammetry, and geomagnetic data acquired over a closed landfill that not only provide detailed and precise measure of the lies on the surface but serves to expand the knowledge of the unseen items buried below surface.
