Arctic Geospatial Data for Cold Region Transportation Infrastructure Analysis: Ground Penetrating Radar Gathered along the Steese Highway, Alaska, 2023

Road subsurface data were collected using a GPR sensor mounted on a cart for several sections of the Steese Highway as part of a continued efforts to provide more geospatial data in Arctic regions relevant to cold region research. The Steese Highway, located in Alaska, is a majorroadway that traverses through the state's interior, providing a vital transportation link within this remote and rugged region. Stretching approximately 261 kilometers, the highway begins in Fairbanks, one of Alaska's largest cities, and extends northward, ultimately connecting with the town of Circle near the Yukon River. The survey was conducted in the summer of 2023. The corresponding GPR data offers geospatial resources for extreme cold weather infrastructure analysis and subsurface visualization.

针对阿拉斯加州斯蒂斯公路的多个路段，研究团队采用安装在手推车上的探地雷达（Ground Penetrating Radar, GPR）传感器采集道路地下数据，此项工作是为北极地区提供更多与寒区研究相关地理空间数据的持续推进举措之一。斯蒂斯公路地处阿拉斯加州，是横贯该州内陆的核心干线公路，为这片偏远崎岖的区域提供了至关重要的交通连接。该公路全长约261公里，始于阿拉斯加最大城市之一的费尔班克斯，向北延伸，最终与育空河附近的锡尔镇相连。本次勘测工作于2023年夏季开展。配套的GPR数据可为极寒气候下的基础设施分析与地下结构可视化提供宝贵的地理空间资源。
