Although this image appears as if it might be an oblique 3D view from an aircraft, it was generated by applying a flat Digital Orthophoto (DOP) as an overlay on the preceding Digital Elevation Model (DEM). The software that performed the conversion is called 3DEM, described in the Toolbox. A DEM provides the elevation frame that holds an overlay. Although this sample image is relatively small, a full-sized picture with high resolution can provide a virtual landscape with uncanny realism.
