Lynch's Elements of Organization

landmark: external to the user, can not go into, prominence in location, use in orientation, may be isolated, not integrated

nodes: small points in the city, user can enter, can be several nodes, can carry a theme, focus of a district, can be dominant feature

district: can be linked together, observer can go inside of, identifiable from the inside but visible from the outside

edges: boundaries between two kinds of areas or content, can have directional qualities

paths: may not be identifiable or continuous, user moves along a path, in this case, the user creates their path
