Boulder Creek Critical Zone Observatory August 2010 LiDAR Survey

2010 Boulder Creek, Colorado Snow-Off LiDAR Surveys<br><br>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 <a href="https://ncalm.cive.uh.edu/" target="_blank">National Center for Airborne Laser Mapping (NCALM)</a> project and the <a href="http://czo.colorado.edu/" target="_blank">Boulder Creek Critical Zone Observatory (CZO)</a>, 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. Together, the LiDAR Digital Elevation Models (DEM) and point cloud data will be of interest to land managers, scientists, and others for study of topography, snow, ecosystems and environmental change. The Boulder Creek CZO will be using the LiDAR data to further their mission of focusing on how water, atmosphere, ecosystems, & soils interact and shape the Earth's surface. The "Critical Zone" lies between rock and sky. It is essential to life - including human food production - and helps drive Earth's carbon cycle, climate change, stream runoff, and water quality.<br><br>PLEASE READ the <a href="https://cloud.sdsc.edu/v1/AUTH_opentopography/www/metadata/BcCZO_10_SnowOff_Metadata_Reports.zip">FGDC-compliant metadata files</a> that are available for each dataset (in .html, .txt, and .xml formats).

2010年博尔德溪，科罗拉多州雪后激光雷达测量数据集

本数据集收集于2010年8月的雪后时期，位于科罗拉多州博尔德市附近博尔德溪流域内的600平方公里区域内。该激光雷达数据的获取由国家空中激光测绘中心（NCALM）项目与博尔德溪关键带观测站（CZO）合作完成，二者均获得美国国家科学基金会（NSF）的资助。数据集包含1米分辨率的数字地表模型（第一档），数字地形模型（裸地），以及每平方米10点的LAS格式点云瓦片。数字地表模型（DSM）和数字地形模型（DTM）均以GeoTIFF格式提供，每个文件大小约为1-2吉字节，附带相关阴影模型，总计数据量约为15吉字节。数字地形模型（DTM）是一个地面高程数据集，更适合用于生成斜率角度、方位和等高线等派生层。附加层包括点云瓦片的索引地图层、数字高程模型（DEM）范围和飞行航线。本系列数据还包括2010年的积雪数据。激光雷达数字高程模型（DEM）和点云数据将引起土地管理者、科学家及其他研究地形、积雪、生态系统和环境影响者的兴趣。博尔德溪CZO将利用激光雷达数据进一步推进其研究使命，即关注水、大气、生态系统与土壤如何相互作用并塑造地球表面。‘关键带’位于岩石与天空之间，对于生命——包括人类食物生产——至关重要，并有助于驱动地球的碳循环、气候变化、河流径流和水质量。
