DTM_NCALM18_FEMA06_WithChannel

Digital terrain model (DTM) of the Mission River landscape at a 1-m spatial resolution. This dataset was developed by fusing lidar-based terrain data from the National Center for Airborne Laser Mapping (NCALM; collected in Mar-2018) as part of an NSF grant (Grant ID: NSF-EAR-RAPID-1760717), a joint data collection in May-2006 by the Federal Emergency Management Agency (FEMA) and the Texas Water Development Board (TWDB), acoustic Doppler current profiler (ADCP) transects (collected in Mar-2018), and channel topographies from FEMA (collected in 2014). The central portions of the dataset are the ones that contain the more recent data and they are what was analyzed when it pertains to the hydrodynamic modeling and the associated surface-water connectivity.
