1. A method for correlating imprecise source data in a local coordinate system to a precise global eyepoint position for a global coordinate system within which the local coordinate system is located within a computer simulated environment, comprising the steps of:

  • identifying key correlation points for the local coordinate system, which has modeling inaccuracies;

    identifying global coordinates for each of the key correlation points;

    computing delta values for each of the key correlation points that represent the difference between key correlation points'"'"' local system coordinates and the global coordinate system'"'"'s coordinate values for the key correlation points;

    and modifying the global eyepoint position based on delta values for selected key correlation points as the global eyepoint position moves in relation to the local coordinate system and the global coordinate system;

    displaying an image of the computer simulated environment to a user based on the modified global eyepoint position.
