This report contains the results of the first phase of the 3D Cadastre and LADM investigations in context of possible future renewal of the Cadastral database at the Survey of Israel. This report complements the presentations given on ‘3D Cadastres’ and ‘Land Administration Domain Model (LADM, ISO 19152)’ on respectively 9 and 10 February 2014 at the Survey of Israel, Tel Aviv. For completeness both presentations are included as annexes to this report. The first phase of the investigations covered two studies: 1. the state of the art of three-dimensional cadastre and 2. current cadastral procedures, land model and database. Both studies focus on Israel, but are conducted from international perspective in order to provide comparison and possible best practises. The two topics of 3D Cadastres and LADM are highly related and therefore this report covers both studies. The report concludes the first phase of the investigations with a series of short and long(er) term recommendations in order to realize the inclusion of 3D Cadastral objects in the registration. In July 2014 the second phase of the investigations is planned and will continue the 3D Cadastre/LADM study (standards, procedures, case studies, SDI, LADM country profile, data transfer, DBMS schema, query and visualization) and prepare for future 5D Cadastre research (2D/3D integration, temporal, legal-physical objects, vario-scale).
