The production of space is a view of landscape as a process of creating and negotiating social interactions within particular spaces. What remains of past productions are the traces and vestiges, as cultural expressions or "signs" of these productions. A "ghost excavation" works with what remains of these past productions. This is achieved through an analysis of the structure and process of past social construction. Fieldwork involves the recovery of an "afterlife semiotic system" (or "haunting") of what remains from those past productions. The "ghost excavation" is an alternative, non-paranormal, analysis of haunted space.
