SSHCZO -- LiDAR, Vegetation -- Shale Hills -- (2010-2010)

High-resolution LiDAR survey covers an area of 170 km2 located 10 miles southwest of State College, Pennsylvania. The data collection was funded by the National Science Foundation (NSF) and performed by the National Center for Airborne Laser Mapping (NCALM) during peak leaf-on and leaf-off conditions in 2010 (July 2010 and December 2010, respectively). The dataset contains point cloud tiles in LAS format, 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 were used to estimate vegetation biomass and distributions, provide bare earth elevations, and to assist with prediction of Critical Zone creation and structure. Horizontal coordinate system UTM 18N NAD83 meters, vertical coordinate system NAVD88.

高分辨率激光雷达测绘覆盖了位于宾夕法尼亚州State College西南方向10英里处，面积为170平方公里的区域。该数据收集项目由美国国家科学基金会（NSF）资助，并由国家航空激光测绘中心（NCALM）在2010年的叶落和叶生高峰期（分别于2010年7月和12月）执行。数据集包含LAS格式的点云瓦片，由第一站点计算得出的1米分辨率数字表面模型（DSM），由地面分类点计算得出的1米分辨率数字高程模型（DEM），以及由DEM派生的1米阴影数据集。这些数据集被用于估算植被生物量和分布、提供裸地高程以及辅助预测关键地带的形成与结构。水平坐标系统为UTM 18N NAD83米，垂直坐标系统为NAVD88。
