Zusammenfassung	Townscape analysis is the appraisal of the visual and physical character of towns, combining two traditions: Gordon Cullen's 'serial vision' approach, which reads the town as a sequence of unfolding views experienced by a moving observer, and the Conzenian school of urban morphology, which dissects the town through its plan, building fabric, and land use. Cullen's 1961 The Concise Townscape argued that the art of the environment lies in the relationships and emerging views between buildings and spaces, not in the objects alone. Together the two strands give townscape analysis both an experiential, qualitative side and a systematic, morphological one.	Isovist analysis describes the experience of space by computing, for any vantage point, the exact region that is visible from it — the isovist, or visibility polygon. Introduced by Michael Benedikt in 1979, the method turns intuitive notions of openness, enclosure and prospect into measurable quantities such as the area, perimeter and compactness of the visible field. By repeating the construction across a grid of points one obtains an isovist field that maps how visibility varies throughout a building or urban space, making it a core analytic tool in space syntax, architecture and environmental psychology.
