Mobile lidar scanners are mapping underground spaces in Belfast to better understand and prepare for coastal flooding. The use of SLAM-based systems provides greater clarity of large flood risk areas for surveyors, through the creation of flood models. Globally, lidar solutions help to create the foundations for flood modeling of large areas, however, they seldom consider mapping underground spaces. UrbanArk, a joint research project under the US-Ireland research and development program, seeks to change this by using modern lidar technologies (SLAM-based systems).
