Shape_of_Flightline_Water_Differences:

The temporal differences between flightlines caused some water level differences to appear in the LiDAR data between flight missions. Due to these water level differences, the hydroflattened bare earth model could not be created to flow downhill continually. This shapefile identifies those areas in the Colorado River Basin Post Pulse LiDAR survey that have visible water differences due to flight times, and as such could not guarantee downhill stream flow.
