Idaho Lidar Consortium (ILC): Clear Creek

The lidar survey was conducted by vendor Earth Eye LLC, 3680 Avalon Park Blvd. The data were delivered in LAS 1.1 format with information on return number, easting, northing, elevation, scan angle, and intensity for each return. This project is the data acquisition phase of a administrative study being done in collaboration with the Nez Perce National Forest, Grangeville, ID; Forest Service Region 1 Regional Office, Missoula, MT (Forest Inventory and Analysis and Remote Sensing/ Geospatial Team); and Rocky Mountain Research Station - Forest Sciences Lab, Moscow, ID. The primary goal of the study is to provide operational implementation of Lidar technology in support of project level planning. The proposed applications of Lidar in support of planning are: vegetation structural modeling, erosion modeling, fuels, transportation planning, timber system planning, wildlife habitat modeling, and stream quality. The Rocky Mountain Research Station will provide the development of peer-reviewed forest structural metrics and technical support in implementation of Lidar technology. The technical specifications have been defined to specifically support vegetation modeling using Lidar data. The project area consists of one contiguous blocks totaling 17, 325 hectares in north central Idaho. The project area consists of moderately variable topographic configurations with diverse vegetation components. Clear Creek is a tributary of the Middle Fork Clearwater River located east of Kooskia, Idaho. Vegetation is variable, transitioning from low elevation shrubland and mixed conifers to upper elevation spruce-fir. Ponderosa pine (Pinus ponderosa) and Douglas-fir (Pseudotsuga menziesii) are the predominant species at lower to mid elevations occupying a fairly xeric setting transitioning to grand fir (Abies grandis) and western red cedar (Thuja plicata) at mid elevations and subalpine fir (Abies lasiocarpa) at the higher elevations.

该激光雷达测量工作由Earth Eye LLC公司执行，该公司位于加利福尼亚州阿瓦隆公园大道3680号。数据以LAS 1.1格式交付，其中包含了关于每个反射的返回次数、经度、纬度、高程、扫描角度和强度的信息。此项目是行政研究的数据采集阶段，该研究由内兹珀斯国家森林（位于爱达荷州格兰奇维尔）、森林服务第一区域办公室（位于蒙大拿州密苏拉）、森林资源调查与分析以及遥感/地理空间团队以及落基山研究站——森林科学实验室（位于爱达荷州莫斯科）共同协作完成。该研究的主要目标是提供激光雷达技术在项目规划层面的实际应用实施。激光雷达在规划支持方面的预期应用包括：植被结构建模、侵蚀建模、燃料管理、交通规划、木材系统规划、野生动物栖息地建模以及溪流质量监测。落基山研究站将负责开发经过同行评审的森林结构指标，并提供激光雷达技术应用的技术支持。技术规范已被明确制定，以特别支持利用激光雷达数据进行植被建模。项目区域由一个连续的区块组成，总面积为17,325公顷，位于爱达荷州北中部。该区域地形多样，植被成分丰富。克莱尔克里克是位于爱达荷州库斯奇亚以东的克莱尔河中游支流。植被类型多变，从低海拔灌木丛和针叶混交林过渡到高海拔的云杉-冷杉林。ponderosa松（Pinus ponderosa）和Douglas冷杉（Pseudotsuga menziesii）是中低海拔区域的主要树种，占据着半干旱的环境，并向着中等海拔的 grand冷杉（Abies grandis）和西部红杉（Thuja plicata）以及高海拔的亚高山冷杉（Abies lasiocarpa）过渡。
