Arctic Geospatial Data for Cold Region Transportation Infrastructure Analysis: High-Resolution LiDAR Point Clouds along the Steese Highway, Alaska, January 2024-Site_5

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 on previous test sites that were tested during the summer 2023 field study exercise on Alaska's Steese Highway, as part of continued efforts to provide more geospatial data in Arctic regions relevant to cold region research. The Steese Highway is a major highway connecting the city of Fairbanks, Alaska, to the small town of Circle, Alaska, near the Yukon River. The Steese Highway spans approximately 261 kilometers and is the only means of transportation for goods and supplies to the remote towns of both Central and Circle Alaska. The survey was conducted in January 2024 as a companion comparative dataset to the summer 2023 LiDAR dataset. The corresponding point cloud data shows evidence of road degradation and snow accumulation.

遥感技术可实现快速、精准且无损的数据采集，并能够近乎实时地获取偏远地区的观测数据。本次采集的激光雷达（LiDAR）传感器数据，来自2023年夏季在阿拉斯加州斯蒂斯公路（Steese Highway）开展野外调研时所使用的前期测试站点，本项工作是为与寒区研究相关的北极区域提供更多地理空间数据的持续努力的组成部分。斯蒂斯公路是一条重要干线公路，连接阿拉斯加州费尔班克斯市与育空河附近的阿拉斯加州瑟克尔小镇。该公路全长约261公里，是阿拉斯加州森特罗尔与瑟克尔这两个偏远城镇获取物资与补给的唯一交通通道。本次野外调查于2024年1月开展，作为2023年夏季激光雷达数据集的配套对比数据集。配套的点云数据显示，该路段存在道路退化与积雪堆积现象。
