A method and system are provided for relating a passive sensor (14) to a geographic environment (42, 44). The passive sensor (14) senses an image (40) of the geographic environment (42, 44). At least one feature (46) is extracted (26) from the image (40). At least one feature is generated (30) from map data (28) representative of the geographic environment. At least one extracted feature is related (22, 32) to at least one generated feature, such that the passive sensor (14) is related to the geographic environment (42, 44).
