Line of Sight

SOCET GXP allows users to view elevation data over imagery. To study an image in fine detail using SOCET GXP, evaluation tools for enhanced viewing are combined with a digital elevation model. The color and detail of the terrain being viewed are controlled through the terrain display preference node or through the terrain visualization properties window, accessible from the terrain visualization toolbar.

The terrain visualization toolbar is available on the Multiport via a right-click from the toolbar area on the Multiport.

Tip

To view terrain data without an image, select View > Visibility > Raster to turn the image on and off.

Hot-key hint

Press the F4 key to re-center the image on the Multiport to the current cursor position.
