Lidar-derived digital surface and elevation models of a stream channel
The above image is a rendering of a lidar-derived digital surface model overlaying a digital elevation model of a forested stream channel in central Iowa. The vegetation makes optical identification of the presence of water in channels difficult.

Lidar-derived digital elevation model and NHD stream lines
The above image is a rendering of a lidar-derived digital elevation model of a low relief stream channel and associated National Hydrography Dataset line features in central Iowa. The low topographic relief makes flow accumulation modeling of surface water difficult.

100m resolution elevation model with hydro
The above image shows Eastern Great Plans and Central Interior Appalachian landscape features spanning much of Missouri, Illinois, and Indiana as depicted with a 100-meter resolution elevation model overlain with 1:2,000,000-scale hydrographic features.
