To better manage data in agriculture, governmental services implement geoinformation systems. These systems may be used as an aid to calculation of subsidies, serve as means of control and as support in decision making while following the latest technologies and standards. One of the oldest policies of the EU, the Common Agricultural Policy, implements a system for agricultural subsidies along with an information system to aid in enforcing it. This paper provides one design for an exhaustive geoinformation system in the Republic of Serbia and verification of the mentioned system with test data. The system must fulfil requirements and standards as one of the conditions for accessing the EU. These needs are met by extending the current Serbian framework while conforming to directives and standards such as INSPIRE, ISO/LADM and LPIS. A suggestion is shown in the paper for using this system in communicating and presenting relevant data to the farmers through a geoportal Web application which also serves as a way of verifying the system.

Three-dimensional (3D) real property has been the subject of increased research activity during the last decade. This article continues the discussions of the legal framework sessions at the 4th international workshop on 3D cadastres in Dubai 2014 in order to further develop and analyse the legal concepts of 3D real property, and presents an overview of experiences from 3D property use and registration. The outcome is intended to initiate discussions on the legal framework of 3D cadastres and aims at identifying the main topics concerning the legal aspects of 3D property and cadastre.

The objective of this discussion is the Austrian land cadastre, which forms the basis of the Austrian land information system, together with the land registry. From a data structure perspective, the Austrian land cadastre is a traditional parcel-oriented system and includes a geometric description of land plots linked to other records describing the nature of the land plots. The changeable institutional (legal) framework was shaped the continuous development of the Austrian land cadastre since the first systematic land survey and cadastral mapping at the beginning of the 19th century. With the progress of information technology in recent decades, it has been developed into a contemporary land information system, which (together with the land registry) provides up-to-date land information. It has to be emphasized that the current land cadastre still contains some data from its very beginning and, for this reason, the historical development of this evidence, including data sources, is of great importance for users of these data. The first part of the article provides an introduction to the historical development of the Austrian land cadastre, followed by the presentation of contents and procedures of the current land cadastre.
