Topographic stress controls, San Bernardino Mountains, CA 2017

This dataset, located within the San Bernardino Mountains, CA, was collected as an NCALM Seed grant for Jessica Lin, University of California, Los Angeles, Earth, Planetary, and Space Sciences Department to support an investigation of topographic stress control on subsurface weathered zone and seismic site conditions in southern California. The requested survey area is located approximately 11 km north of San Bernardino, CA. The polygon encloses approximately 62 km². Note: A considerable percentage of the points in this dataset were classified as \"building\" (LAS class 6) although visual inspection indicates these points are mostly above-ground vegetation. For the purposes of distribution though OpenTopography, these points have been grouped with \"unclassified\" (LAS class 1) points to reduce point cloud classification to either \"ground\" or \"unclassified\" below.<p><br>Publications associated with this dataset can be found at <a href=\"http://calm.geo.berkeley.edu/ncalm/dtc.html\" target=\"_blank\">NCALM's Data Tracking Center</a></p>本数据集采集自美国加利福尼亚州圣贝纳迪诺山脉，由加州大学洛杉矶分校地球、行星与空间科学系的Jessica Lin申请的NCALM种子基金资助，旨在探究加利福尼亚南部地区地形应力对地下风化带及地震场地条件的调控作用。本次申请的勘测区域位于加利福尼亚州圣贝纳迪诺以北约11公里处，该多边形覆盖区域面积约62平方千米。注意：本数据集中有相当比例的点被归类为"建筑"（LAS类6），但目视检查显示这些点大多为地表植被。为通过OpenTopography进行数据分发，上述点已与"未分类"（LAS类1）点合并，将点云分类精简为"地面"与"未分类"两类。<p><br>与本数据集相关的研究成果可在<a href="http://calm.geo.berkeley.edu/ncalm/dtc.html" target="_blank">NCALM数据追踪中心</a>查询。
