Flathead Lake Biological Station, MT (September 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 September 14, 2005 and completed on September 15, 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 May 2005: <a href="http://opentopo.sdsc.edu/lidarDataset.jsp?opentopoID=OTLAS.052013.26912.2"title=Flathead Lake Biological Station, MT (May 2005)">Flathead Lake Biological Station, MT (May 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，项目负责人为马克·洛兰，蒙大拿大学-密苏拉分校。调查区域位于蒙大拿州卡利斯佩尔东北方向40公里的90平方公里区域内。该区域于2005年9月14日进行飞行采集，并于9月15日完成。收集Nyack洪泛平原位于Flathead河中游的激光雷达数据，旨在多个目的。首先，为放置地下水井网络提供基础影像；其次，结合航空和卫星的光学遥感数据，识别多光谱光学影像中对应不同植被高度等级的像素，这些像素随后被根据植被类型进行单独分类。数据还用于对洪泛平原进行简单的洪水淹没建模，并结合流速和流速的测量，从激光雷达中提取水面高程，以绘制河流功率的空间分布图。该区域自2005年5月已有重复调查：<a href="http://opentopo.sdsc.edu/lidarDataset.jsp?opentopoID=OTLAS.052013.26912.2" title="Flathead Lake Biological Station, MT (May 2005)">Flathead Lake Biological Station, MT (May 2005)</a>。与该数据集相关的出版物可查阅于<a href="http://calm.geo.berkeley.edu/ncalm/dtc.html" target="_blank">NCALM数据跟踪中心</a>。
