3D Land Administration

Abstract

This paper refers to the creation or update, organisation and initial analysis of the results from the 4th FIG 3D Land Administration Questionnaire, as an activity of the FIG Working Group 3D Land Administration 2022-2026.

The questionnaire on 3D Land Administration is conducted as a successor of the previous questionnaire on 3D Cadastres, which has been conducted three times till today, by the Working Group in 2010, 2014 and 2018. The first, documented the status in 2010 and expectations back then for 2014. This was followed by the second questionnaire (status 2014 and expectations 2018) and the third one (status of 2018 and plans for 2022).

All members/ countries the Working Group have been requested to provide information about the current the status of 3D Land Administration Systems/ Cadastres (at the end of 2022) and the expectations/plans for 2026. The purpose of the survey that is has been conducted and reported in this paper, is to make an inventory of the status of 3D Land Administration at the end of 2022 and the plans/ expectations for the near future (2026) from countries all over the world.

The completed questionnaires, per country are fully available via the participants’ page of the 3D Land Administration Working Group website. The responses have been analysed and reported in various publications (van Oosterom et al. 2011, van Oosterom et al. 2014 and Shnaidman et al., 2019). In total, thirty-seven (37) countries have completed the questionnaire and have been received by time of conducting the initial analysis as described in this paper. Similar to the previous questionnaires, it is likely that there will be some completed questionnaires that will be sent by the countries later.
