platform
A flat structure with clearly defined edges, usually raised above its surroundings and used for activities on its surface.
A platform is a flat structure, usually elevated from its surroundings, with clearly defined edges. It may be used for staging, transferring, loading, landing, or other purposes.
Platforms do not include outdoor stations, which usually include a platform as a major component.
The defined surface can support activities such as staging, loading, or landing. Its elevation above the surroundings is usual without being mandatory; a complete outdoor station has a broader combination of components.
