A system (100) and method for augmenting synthetic vision system (SVS) databases with spectrum diverse features that are matched to the observations of natural scenes derived from non-visible band sensors. The system correlates sensor output (130) with a-priori information in databases (254) to enhance system precision and robustness. Multiple diverse sensors (132, 134, 136, 138) image naturally occurring, or artificial features (towers buildings etc.) and store the multi-spectral attributes of those features within the enhanced multi-spectral database and share the information with other systems. The system, upon 'live' observation of those features and attributes, correlates current observations with expected fiducial observations in the multi-spectral database (254) and confirms operation, navigation, precise position, and sensor fidelity to enable autonomous operation of an aircraft (120) employing the system.
