The 3D Cadastre pages are available at http://www.gdmc.nl/3DCadastres Position within the FIG The Working Group functions as an inter-commission activity between commissions 3 (Spatial Information Management) and 7 (Cadastre and Land Management) and will report to both.

Mode of operation At FIG events in the past many people have expressed interest in 3D Cadastres. In order to push ahead it seems best if the specific themes of 3D Cadastres (legal, institutional and technical) are lead by a limited number of experts (2-4) who elaborate on their subject. People can then join these groups for discussion and preferably contributions. Task of the chair is to start and encourage these theme-groups, lead the overall issues of the Working Group, and trigger the necessary events. It seems wise to evaluate this way of working from time to time. Communication during the projects will be done as much as possible by e-mail and via our dedicated website. At the end of each year a progress report will be available to all members of the Working Group and to our sponsors in commissions 3 and 7.
