Abstract:
1. A flight display system for providing a safe depiction of global space data, comprising: a sensor system determining a position and orientation of an aircraft; a terrain application system generating a plurality of real time terrain images based on said position and orientation of said aircraft provided by said sensor system, said plurality of real time terrain images containing a plurality of polygons having a visual error bound less than a desired error threshold, wherein said terrain application system utilizes a view dependent error metric to define and maintain said visual error bound and said terrain application system utilizes a level of detail method and a real time optimally adopting meshes method; a terrain database server providing terrain data to said terrain application system upon request of said terrain application system; and a display system displaying said plurality of real time terrain images generated by said terrain application system, wherein said terrain data is represented by a regular grid terrain mesh.
