4D spatio-temporal laser scan dataset of the beach-dune system in Noordwijk, NL

From July 2019 to June 2022 a stationary laser scanner, installed on top of the balcony of Grand Hotel Huis ter Duin was used to survey the beach-dune system at the coast in Noordwijk, The Netherlands. The observed area is about 1000 m long and, depending on the tides, about 350 m wide and includes dunes and a sandy beach.A total of 21812 hourly scans were obtained from July 11^th 2019, 14:00 until June 21^st 2022, 12:00. Each scan produces a 3D point cloud containing about 4 million points depending on atmospheric conditions and the tide-dependent width of the beach. Additional attributes such as the laser return intensity are available for each individual 3D point record.

2019年7月至2022年6月，研究人员将固定式激光扫描仪（stationary laser scanner）安装于荷兰诺德韦克市Grand Hotel Huis ter Duin酒店的阳台顶部，用于对当地海岸的滩涂-沙丘系统开展测绘调查。本次观测区域长约1000米，宽度随潮汐变化约350米，涵盖沙丘与沙滩区域。本次研究共获取21812次每小时扫描数据，时间跨度为2019年7月11日14:00至2022年6月21日12:00。单次扫描可生成三维点云（3D point cloud），单份点云包含约400万个点，实际点数会根据大气条件以及潮汐变化导致的滩涂宽度有所差异。每个三维点记录还附带激光回波强度等额外属性信息。
