Idaho Lidar Consortium (ILC): South Fork Salmon and Secesh Rivers

These LAS and associated files cover areas of the Payette and Boise National Forests, Idaho, and were collected for and processed by the USDA Forest Service, Moscow, ID in cooperation with Watershed Sciences Inc. of Corvallis Oregon, as a part of a project to use Lidar to study wildfire effects on forest canopy structure and hillslope erosion patterns. Data included with this set include the original .las data tiles, a shapefile delimiting the extent and placement of all of these tiles, another shapefile delimiting the total extent (boundary) of the data , and a vendor's report in PDF format detailing the data collection, processing, and error-checking steps. The data are in LAS 1.0 format with information on return number, easting, northing, elevation, scan angle, number of returns of given pulse, intensity, user data, point source ID, and GPS time.本数据集包含的LAS格式（LAS）文件及关联文件，覆盖美国爱达荷州佩耶特国家森林与博伊西国家森林辖区范围。本数据由位于爱达荷州莫斯科市的美国农业部林务局（USDA Forest Service），联合俄勒冈州科瓦利斯的流域科学公司（Watershed Sciences Inc.）共同采集并处理，作为某研究项目的组成部分，该项目旨在借助激光雷达（LiDAR）技术，探究野火对森林冠层结构及山坡侵蚀模式的影响。 本数据集附带的数据内容包括：原始LAS格式分幅数据文件、用于标注所有分幅数据范围与布设位置的形状文件（shapefile）、用于划定本数据集整体范围（边界）的另一形状文件，以及一份PDF格式的服务商报告，该报告详细说明了数据采集、处理流程与误差核查步骤。 本数据集采用LAS 1.0格式，包含的点云属性信息如下：回波序号、东向坐标、北向坐标、高程、扫描角、单脉冲总回波数、强度值、用户自定义数据、点源ID以及GPS时间戳。
