title: Establishing an urban digital cadastre: analytical reconstruction of parcel boundaries
abstract: A new method for generating a spatially accurate, legally supportive and operationally efficient cadastral database of the urban cadastral reality is described. The definition and compilation of an accurate cadastral database (achieving a standard deviation smaller than 0.1 m) is based on an analytical reconstruction of cadastral boundaries rather than on the conventional field reconstruction process. The new method is based on GPS control points and traverse networks for providing the framework; the old field books for defining the links between the various original ground features; and a geometrical and cadastral adjustment process as the conceptual basis. A pilot project that was carried out in order to examine and evaluate the new method is described
