COVER STORY

Depicted on the front cover of this issue: High-density (30 points per metre) elevation data of Chicago, IL, USA, collected using Harris Corporation’s proprietary Geiger-mode Lidar sensor. Geiger-mode and single-photon Lidar are very suitable for large-scale surveying jobs as these technologies enable the survey of extensive areas at lower costs.                                                                                                                                (Courtesy: Harris Corporation)
