Reference Berms in Selected Rangeland Sites in Arizona and Colorado

This dataset includes reference berms in selected rangeland study sites in Arizona and Colorado. The berms were manually identified from 1 m lidar DEMs collected during 2015-2020. Berm centerlines were provided as polylines stored as ESRI shapefiles. A berm made of multiple segments is considered as a single berm. Only berms taller than 0.6 m are included in this dataset.本数据集收录亚利桑那州与科罗拉多州选定牧场研究样地内的参考土埂。所有土埂均从2015至2020年采集的1米分辨率激光雷达数字高程模型（LiDAR DEM）中人工识别得到。土埂中心线以多段线格式提供，存储于ESRI形状文件（ESRI Shapefile）中。由多个分段构成的土埂将被视作单个土埂。本数据集仅收录高度超过0.6米的土埂。
