本数据集为首钢滑雪大跳台2022年1月至4月的储雪堆数据，地理位置为(39.908°N, 116.147°E, 75.8 m a.s.l.)。本数据集共包含1个.xlsx文件和一个TIFF文件，包括距表面1.2m处雪堆内部温度（℃）和储雪堆2022年1月DSM模型（m）。", "ds_source": "
雪堆内部温度使用热敏电阻传感器获取，精度为± 0.02℃ （-30℃～30 ℃）。DSM由三维激光扫描仪扫描的点云数据生成。三维激光扫描仪使用的型号为Riegl VZ®-6000 Class 3B，激光脉冲重复率为300kHz，精扫的角分辨率为0.01°，扫描精度为± 15 mm。", "ds_process_way": "
雪堆内部温度未经加工处理。经点云数据的滤波、拼接、控制点的校正和裁剪等导出目标雪堆的点云数据，在arcgis中输入导出点云最终形成雪堆DSM模型。", "ds_quality": "
