FIG Commission 7 - Cadastre and Land Management

Working Group 7.1
Cadastre Technologies and Smart City

Policy Issues

There are multiple technologies being offered for surveyors as part of their activities in the development of cadastre and land management systems. Many of these technologies are unknown to many surveyors, and there is limited understanding of the role, if any, of these technologies.

To address this, working group 7.1 will focus on exploring these new technologies with a critical eye and on building capacity within the surveying community to ensure the best use of the technology and the competitiveness of cadastre surveyors in the market.

Digital twin and Smart City, in particular, are emerging as key topics to improve transportation, energy, social safety and to decrease pollution caused by climate change and urbanization. To solve these problems, total efforts are being made on the smart city construction with all the latest technologies such as Drones, Artificial Intelligence (AI), Big Data, Robot Technology, Virtual Reality (VR) and Augmented Reality (AR) Technology for the era of the Fourth Industrial Revolution. And a smart city can be completed using the platform base called the Digital Twin.

Finally, smart cities are being built to solve the problems of cities that have reached their limits and to ensure sustainability, and eventually, smart cities will change the paradigm of urbanization around the world with the continuing growth of cities and the construction of human-centred smart cities that improve the quality of citizen’s life.

What's New

Digital twin and future land technologies

All the new technological trends occurring in our daily life - such as mobile devices, automation and cloud systems - are also influencing how land information systems, both in the private and public sector, are developed. In 2019, Korea LX (their national cadastre institution) hosted an outstanding Commission 7 meeting in where countries around the world showcased their development, challenges and opportunities. Korean are leading the way on the digital twin followed closely by important developments in Australia and UK.

The contributions of all participating in the Annual meeting have been put in a summary video by Dr Rohan Bennet (see this link:

For this Working group we are planning a white paper on the digital twin in 2021.
