CJCZO -- LiDAR -- Snow-on -- Jemez River Basin -- (2010-2010)

High-resolution LiDAR survey covers an area of 280 km2 in the upper part of the Jemez River basin, New Mexico. The data collection was funded by the http://nsf.gov/' target='_blank National Science Foundation (NSF) and performed by the http://www.ncalm.cive.uh.edu ' target='_blank National Center for Airborne Laser Mapping (NCALM) during peak snowpack 2010 (March 27 – April 3, 2010). The dataset contains point cloud tiles in LAS format with the average point density of 8.97 p/m2, 1 m Digital Surface Model (DSM) derived using first-stop points, 1 m Digital Elevation Model (DEM) derived using ground-class points and 1 m hill shade dataset derived from DEM. These datasets, together with the snow-off LiDAR survey performed in Jun –July 2010, are being used to estimate snowpack, vegetation biomass and distribution, and bare earth elevations to help better understand and quantify ecosystem structure, geomorphology, and landscape processes within the Critical Zone Observatory.

该高分辨率激光雷达调查覆盖了新墨西哥州杰梅兹河流域上游280平方公里的区域。数据采集由美国国家科学基金会（National Science Foundation, NSF）资助，并由国家航空激光测绘中心（National Center for Airborne Laser Mapping, NCALM）在2010年峰值积雪期间（2010年3月27日至4月3日）执行。该数据集包含LAS格式的点云瓦片，平均点密度为8.97个点/平方米，基于首次接触点生成的1米数字地表模型（Digital Surface Model, DSM），基于地面分类点生成的1米数字高程模型（Digital Elevation Model, DEM），以及由DEM派生的1米阴影数据集。这些数据集与2010年6月至7月进行的雪后激光雷达调查相结合，正被用于估算积雪量、植被生物量和分布，以及裸地高程，以有助于更好地理解和量化关键带观测站内的生态系统结构、地貌和景观过程。
