Landmark Knowledge

A type of spatial knowledge involving the recognition and memory of distinctive features or objects in an environment that serve as reference points for navigation. Landmarks are fixed objects at specific locations—such as a doorway, a change in floor material, or a particular sound—that help people orient themselves and understand where they are. For people with visual impairments, landmarks may be auditory (a fountain, traffic sounds), tactile (a textured surface, a curb), or olfactory (a bakery, a garden). Landmark knowledge is considered more fundamental than route knowledge or survey knowledge, as landmarks are typically learned first and then integrated into route sequences and mental maps.
