Perimeters and cartographic grids constitute a network of overlying lines on the landscape delimiting the margins or intersections of sites. This thematic program area examines the edges of places, which are often distinct places in themselves, and the interaction of physical space with conceptual lines. The structures that emerge along linear transpositions, such as fences, berms, and signage, are part of this land use language.
