High Resolution Digital Elevation Models (DEMs) are produced from both the natural color and multispectral imagery as part of the differential rectification orthophoto process. When orthophoto mosaics are draped over their DEMs, they give a more realistic view of the landscape within its topography. These 3D views can be used to model watersheds, measure slope and aspect, or interactively explore the landscape and present it in new ways. The DEMs can also be used directly to model forest canopies and measure tree height.
