NEON (National Ecological Observatory Network) Elevation - LiDAR (DP3.30024.001)

Bare earth elevation surface (DTM) and actual surface (DSM) given in meters in the NAVD88 (Geoid12A realization) vertical reference frame. Horizontal coordinates referenced to appropriate UTM zone. Bare earth is created by classifying and removing vegetation and man-made structures from lidar point cloud prior to surface generation. Both the DSM and DTM are mosaicked onto a spatially uniform grid at 1 m spatial resolution in 1 km by 1 km tiles provided in a geotiff format.

该数据集提供了基于NAVD88（Geoid12A实现）垂直参考框架的裸地高程表面（DTM）和实际表面（DSM），单位为米。水平坐标参照相应的UTM区域。通过在生成表面之前对激光点云进行分类和去除植被及人工结构，创建裸地。DSM和DTM均被镶嵌在空间上均匀的1米分辨率的网格上，并以1公里×1公里的瓦片形式提供，格式为地理TIFF。
