Spatiotemporal expression and application of urban residential solar rights based on CityGML-LADM

Property disputes are frequent occurrences in rapidly urbanizing regions. Among the legal issues concerning building property rights, solar rights prevalent because text clauses on rely diverse measurements or calculations. Moreover, previous studies measuring addressed only sunlight duration and neglected daylight factor (daylighting coefficient), which is an integral component of rights. Therefore, this study proposes a 3D spatiotemporal model for effectively by taking both into consideration. This would be technologically valuable avoiding settling disputes. Taking specifications China as case study, proposed clarifies complete residential units implemented integrating geometric from CityGML with model, namely, Land Administration Domain Model (LADM). Three real typical cases adopted to show applicability benefit resolving
