    Collection Overview: 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: Flathead Lake Biological Station, MT (September 2005).
