Point Cloud Data for Arctic Highway and Bridge Freeze-Thaw Cycle Damage Assessment: High-Resolution LiDAR Data from the Dalton Highway (South Fork Bonanza - North Fork Bonanza), AK.

Remote sensing makes it possible to gather data rapidly, accurately, and non-destructively, allowing for access to remote areas in near real-time. LiDAR sensor data were collected along Alaska's Dalton Highway as part of continued efforts to provide more geospatial data in Arctic regions relevant to cold region research. The Dalton Highway, also referred to as Alaska Route 11, is a remote and vital transportation corridor extending approximately 414 miles from Livengood to Deadhorse near the Arctic Ocean. The highway plays a critical role in facilitating access to the Prudhoe Bay Oil Fields and is a key logistical route for energy development in the region. Two bridges were represented in this dataset, one across the South Fork Bonanza Creek and the other across the North Fork Bonanza Creek. The South and North bridges are located 9 mi and 10 mi, respectively, from the famous Arctic Circle Sign. The survey was conducted in August 2024; the corresponding point cloud data shows evidence of road degradation, the bridges, as well as other features of the environment. This dataset offers valuable information for permafrost analysis, machine learning, terrain analysis, and landscape monitoring.

遥感技术可实现快速、精准且无损的数据采集，支持近乎实时地获取偏远区域的观测数据。作为北极寒区研究相关地理空间数据补充工作的一部分，研究团队沿美国阿拉斯加州道尔顿公路（Dalton Highway）采集了激光雷达（LiDAR）传感器数据。道尔顿公路又名阿拉斯加11号公路，是一条偏远却至关重要的交通廊道，全长约414英里，起于利文古德，止于北冰洋附近的戴德霍斯。该公路是通往普拉德霍湾油田的关键通道，同时也是本地区能源开发的核心后勤运输线路。本数据集涵盖两座桥梁：一座横跨博南扎溪南支流，另一座横跨博南扎溪北支流。南、北两座桥梁分别距离知名的北极圈标识点9英里和10英里。本次数据采集于2024年8月，配套的点云数据可观测到道路退化痕迹、桥梁及其他环境地物特征。本数据集可为多年冻土分析、机器学习、地形分析及景观监测提供宝贵的支撑数据。
