Terrestrial lidar data from the 2017 Upper Scenic Drive Landslide, La Honda, California: classified point cloud and gridded elevation data from 2016-2017

This dataset consists of point cloud data collected in 2016 and 2017 of the lower and upper Scenic Drive landslide locations in La Honda, California. Point cloud data were collected in 2016 to establish baseline for movement detection of past landslides. Point cloud data were collected in 2017 adjacent and upslope of 2016 data to document a newly formed landslide. The data were collected with a Riegl VZ400 Terrestrial Laser Scanner and georeferenced using a Leica Viva GS15 survey grade GPS. The data are delivered as georeferenced (NAD83 UTM zone 10N ellipsoid) classified point clouds, 5 cm resolution digital elevation models, and a text file of surveyed GPS control points. The included files are: LH2017_Jan.laz LH2016_Jan.laz LH2017_5cm_DEM_be_tin.tif LH2017_5cm_DEM_bebldg_tin.tif LH2017_5cm_DEM_be_idp.tif LH2016_5cm_DEM_be_tin.tif LH2016_5cm_DEM_bebldg_tin.tif LH2016_5cm_DEM_be_idp.tif LH_GPS_control_points_NAD83_UTM_z10N_ell.txt

本数据集包含2016年与2017年采集的、位于美国加利福尼亚州拉洪达（La Honda）上下段风景道（Scenic Drive）滑坡点位的点云数据。2016年采集的点云数据用于建立既往滑坡运动检测的基准；2017年采集的点云数据布设于2016年数据采集区域的邻近上坡地带，用于记录新形成的滑坡。
数据采集采用Riegl VZ400地面激光扫描仪（Terrestrial Laser Scanner），并使用徕卡（Leica）Viva GS15测量级GPS完成地理配准。
本次交付的数据包括采用NAD83 UTM 10N椭球坐标系进行地理配准的分类点云数据、分辨率为5厘米的数字高程模型（Digital Elevation Model, DEM），以及一份GPS测量控制点文本文件。
数据集包含的具体文件如下：LH2017_Jan.laz、LH2016_Jan.laz、LH2017_5cm_DEM_be_tin.tif、LH2017_5cm_DEM_bebldg_tin.tif、LH2017_5cm_DEM_be_idp.tif、LH2016_5cm_DEM_be_tin.tif、LH2016_5cm_DEM_bebldg_tin.tif、LH2016_5cm_DEM_be_idp.tif、LH_GPS_control_points_NAD83_UTM_z10N_ell.txt
