Legal opportunity to implement 3D cadastre in Mongolia

3D GIS Applied to Cadastre

2 Summary 2D cadastre systems have shown limitations, especially when describing complex situations to various stakeholders. 3D information models for cadastre are now increasingly implemented to overcome these restrictions. However, 3D systems are not without their challenges and problems to be avoided. The challenges include: guaranteeing topological consistency when building 3D volumes, dete...

Application of 3D GIS to 3D Cadastre in Urban Environment

Rapid development has promoted the 3D land use in the urban environment with the increasing requirements of the complex interweaving, such as dwellings, commercial areas, public transportation and urban utilities and infrastructure.3D cadastral object are features which concern unban planning, land resource and real estate of municipalities, whether they are on, obove or below the earth’s surfa...

Working with Open BIM Standards to Source Legal Spaces for a 3D Cadastre

Much work has already been done on how a 3D Cadastre should best be developed. An inclusive information model, the Land Administration Model (LADM ISO 19152) has been developed to provide an international framework for how this can best be done. This conceptual model does not prescribe the technical data format. One existing source from which data could be obtained is 3D Building Information Mo...

Data validation in 3D cadastre

In a cadastre, the 2D parcel is nowadays correctly considered to be a special case of the 3D parcel because the rights and restrictions extend beyond the surface itself. Storing, representing and manipulating a true 3D parcel however has not yet been satisfactorily achieved because of constraints in data modeling and software development. Significant research has been done to identify the best ...
