1. A see-through display system, comprising:
- a processing unit configured to receive data representative of geo-referenced symbology and terrain data, to compare the geo-referenced symbology to the terrain data, and to generate display commands associated with the geo-referenced symbology based on the terrain data; and
a display device coupled to the processing unit and configured to receive the display commands from the processing unit and to display the geo-referenced symbology, wherein the processing unit is configured to additionally supply data commands representing terrain symbology based on the terrain data, the display device configured to overlay the terrain symbology onto at least a portion of the geo-referenced symbology.

9. A see-through display system associated with a user at a viewing perspective, comprising:
-
a processing unit configured to receive data representative of first geo-referenced symbology and terrain data, the terrain data including data associated with a first terrain feature, the processing unit further configured to supply display commands associated with the first geo-referenced symbology; and a see-through display device coupled to the processing unit, and configured to receive the display commands from the processing unit and to display the geo-referenced symbology such that the first geo-referenced symbology appears at least partially obscured by the first terrain feature from the viewing perspective. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of displaying geo-referenced symbology in a see-through display for a user at a viewing perspective, the method comprising the steps of:
-
determining a position for geo-referenced symbology; receiving terrain data that includes a terrain feature in front of the position of the geo-referenced symbology from the viewing perspective of the user; generating display control signals associated with the geo-referenced symbology; and displaying the geo-referenced symbology based on the display control signals such that the terrain feature at least partially obscures the geo-referenced symbology. - View Dependent Claims (18, 19, 20)
