Flathead Lake Biological Station, MT (May 2005)

NCALM Project. PI: Mark Lorang, The University of Montana- Missoula. The survey area is an 90 square kilometer box located 40 km northeast of Kalispell, Montana This area was flown on May 29, 2005 and completed on May 30, 2005. Lidar data from the Nyack Floodplain on the Middle Fork of the Flathead River was collected for several purposes. The first was to provide a base image from which we could place a network of groundwater wells. The data was also used combination with optical remotes sensing data, both airborne and satellite, to identify pixels within multispectral optical imagery that corresponded to various vegetation height elevations. Those pixels were then separately classified by vegetation type. Data was also used to conduct simple flood inundation modeling of the floodplain and in combination with measures of flow depth and velocity extracting water surface elevation from the lidar to map the spatial distribution of stream power. This area has a repeat survey from Spetember 2005: <a href=\"http://opentopo.sdsc.edu/lidarDataset.jsp?opentopoID=OTLAS.032013.26912.1\"title=Flathead Lake Biological Station, MT (September 2005)\">Flathead Lake Biological Station, MT (September 2005)</a>.<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>

NCALM项目。项目负责人：马克·洛兰，蒙大拿大学密苏拉分校。调查区域为蒙大拿州卡利斯佩尔东北40公里处的90平方公里矩形区域，该区域的航空飞行作业于2005年5月29日启动，同年5月30日完成。本次收集了弗拉特黑德河（Flathead River）中游支流奈亚克洪泛区的激光雷达（Lidar）数据，其收集目的包括：一是提供基础影像，用于布设地下水井网络；二是结合机载与星载光学遥感数据，识别多光谱光学影像中对应不同植被高度高程的像素，并按植被类型对这些像素进行单独分类；三是用于开展该洪泛区的简单洪水淹没模拟，同时结合水流深度与流速测量数据，从激光雷达数据中提取水面高程以绘制水流功率的空间分布。该区域另有2005年9月的重复调查数据集：<a href="http://opentopo.sdsc.edu/lidarDataset.jsp?opentopoID=OTLAS.032013.26912.1"title=Flathead Lake Biological Station, MT (September 2005)">蒙大拿州弗拉特黑德湖生物站（2005年9月）</a>。<p><br>本数据集相关研究成果可访问<a href="http://calm.geo.berkeley.edu/ncalm/dtc.html" target="_blank">NCALM数据追踪中心</a>获取。</p>
