Four-Dimensional cadastre modeling with UML Diagram

Abstract

In addition to the third dimension in the cadastre, the need for temporal information about
the past is also increasing. Changes may occur in real estate, both legally and geometrically,
over time. It is of great importance in terms of four-dimensional cadastre that these changes
can be monitored instantly in the four-dimensional environment together with the vertical
dimension. In this study, a four-dimensional cadastre design was made using the UML
modeling language, which is a visual modeling language. In this design, along with the
horizontal and vertical positions of the real estates, the fourth dimension, which shows the
temporal changes, and the value element, which is thought to be the fifth dimension of the
cadastre in the future, are partially included. In addition, in this study, using the UML modeling
language, the zoning status of the immovables, the lines passing under and above the
immovable, the type of changes that occurred in the immovables, the time and explanation of
the change were included and their relations with each other were examined.
