Introduction
• In the final decades of the 20th century cadastral
systems were revolutionized
• To remain relevant cadastral science must

Modern Cadastral Theories and Practice
• Prior to modern spatial information systems,
cadastres primarily served fiscal or juridical
functions.
• Post 1970, rapid developments in information
technologies and the push for sustainable
development led to new developments and
applications for the cadastre

• Technological
Drivers
– Integration of CAD and GIS – 3D Visualization – Wireless Sensor Networks – GNSS – Volunteered DataContemporary drivers for the cadastre
• Socio-economic Drivers
– Urbanization of the population – Globalization
Future Cadastres
• Survey-Accurate Cadastres
Future Cadastres

• 3D/4D Cadastres
Future Cadastres
• Real-Time Cadastres
Future Cadastres
• Global or Regional Cadastres
Future Cadastres
• Organic Cadastres
Conclusions
• The drivers for change are clear
– Urbanization, globalization, climate-change, good governance,
environmental management, disaster management, technology
• FIG Commission 7 provides an ideal vehicle for building and testing a new cadastral vision
– History of achievement, capacity in place
• The aim was to begin analysis and provide insights
– Survey-Accuracy, Object-Oriented Cadastres,3D/4D
Cadastres,Real-Time Cadastres,Global Cadastres, and Organic Cadastres
• This is just a starting point…
