Linking LADM with BIM/IFC standards for mobile-based 3D Crowdsourced Cadastral Surveys

The ongoing urbanization has led to the emergence of several complex constructions and multi-dimensional property rights. Traditional cadastral procedures cannot meet the demands of this new reality, leading to increased costs and long delays. Exploiting the capabilities of the latest technologies, mobile services (m-services), Building...

Converting BIM Data to CityGML for 3D Cadastre Purposes

Currently, stratified property rights are registered and managed using two-dimensional subdivision plans. These plans do not accurately depict property spaces in complex structures such as high-rise buildings, tunnels and utilities, underground infrastructures, etc. 3D rich data like building information modelling (BIM) could be utilized as a...

Can Data from BIMs be Used as Input 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. While this generic framework encompasses a wide range of eventualities, it does not prescribe the...

3D Cadastre 1

With more than 50% of the world’s population living in cities, and the proportion of the world’s population living in cities growing to an astonishing 70% by 2050, cities and city infrastructure become an even bigger factor in the quality of life. These numbers reflect the growth of urban areas by 2.5 billion people in the next 40 years which...
