The Crowdsourced Cadastre

摘要

There is nothing new under the sun. Or is there? Cadastral practitioners are becoming increasingly interested in 'crowdsourcing'. Using location-enabled mobile phones, citizens could themselves perform - at least partially -adjudication, surveying, demarcation, and recordation. Some suggest it could revolutionise cadastral establishment and maintenance. At first glance the concept appears highly innovative. It could help lower costs of registration, speed up recording, deliver more complete cadastral coverage, and improve the relationship between citizens and their governments. But, have we been through all this before? As part of GIM International's dialogue on Cadastre 2034, the authors discuss the potential of crowdsourcing applied to cadastres.
