World-wide inventory of the status of 3D Cadastres in 2010 and expectations for 2014

Abstract

In this paper, the background, set-up, and a preliminary analysis of the survey conducted by the FIG joint commission 3 and 7 working group on 3D-Cadastre, 2010-2014 is presented. The purpose of the survey is to make a world-wide inventory of the status of 3D-Cadastres at this moment (November 2010) and the plans/expectations for the near future (2014). Sharing this information improves cooperation and exchange of experiences and supports future developments in different countries and cadastral jurisdictions. The FIG working group will repeat the survey in four years time to evaluate the actual progress. In the questionnaire the concept of 3D-Cadastres with 3D parcels is intended in the broadest possible sense. At the moment of writing, 36 completed questionnaires have been received. Another detailed questionnaire survey is being conducted among the eight cadastral jurisdictions of Australia, and the results from these are also presented and compared to the international situation. At the moment of writing, all completed Australian questionnaires have been received.
