BCCZO -- LiDAR -- Point Cloud Data at OpenTopography.com (Snow off) -- Boulder Creek -- (2010-2010)

LiDAR was acquired for a 600 km2 area inside the Boulder Creek watershed during a snow-off (August, 2010) time slice, near Boulder Colorado. This data was collected in collaboration between the National Center for Airborne Laser Mapping (NCALM) project and the Boulder Creek Critical Zone Observatory (CZO), both funded by the National Science Foundation (NSF). The dataset contains 1 m Digital Surface Models (first-stop), Digital Terrain Models (bare-earth), and 10 points/m2 LAS-formated point cloud tiles. The DSMs and DTMs are available in GeoTIFF format, approx. 1-2 GB each, with associated shaded relief models, for a total of 15 GB of data. The Digital Terrain Model (DTM) is a ground-surface elevation dataset better suited for derived layers such as slope angle, aspect, and contours. Accessory layers consist of index map layers for point cloud tiles, DEM extent, and flight lines. Other LiDAR DSMs, DTMs, and point cloud data available in this series include snow-on data for 2010.

激光雷达数据于2010年8月雪融期间在科罗拉多州博尔德克里克流域内的600平方公里区域内获取。此数据收集工作由国家空中激光测绘中心（NCALM）项目与博尔德克里克关键带观测站（CZO）联合完成，二者均获得美国国家科学基金会（NSF）的资助。数据集包含1米分辨率的数字表面模型（首停模型）、数字地面模型（裸地模型）以及每平方米10点的LAS格式点云瓦片。数字表面模型（DSM）和数字地面模型（DTM）以GeoTIFF格式提供，每个文件约1-2GB，附带阴影模型，总计约15GB数据。数字地面模型（DTM）是地表高程数据集，更适用于生成坡度角、坡向和等高线等派生图层。辅助图层包括点云瓦片索引图、DEM范围和飞行航线图。本系列中还包括2010年的雪上数据集的激光雷达DSM、DTM和点云数据。
