Based on the experience in the design and implementation of cadastral information systems in Serbia, Montenegro and Republika Srpska, an entity in Bosnia and Herzegovina, this paper presents activities in the development of LADM based cadastral profiles in these countries and a region. It also demonstrates the implementation of such profiles in practice in the form of technical solution that combines together software for maintaining cadastral and legal data (both alphanumeric data about rights and spatial data on cadastral maps), office management solution and development of on-line services for the citizens, to have an insight into their rights and restrictions. There are three main subsystems of cadastral information system in these countries and the entity: 1) land register containing alphanumeric data about land, buildings, rights and parties 2) cadastre containing graphic data about land parcels and buildings 3) office management for handling requests made by citizens. Software solution includes the functionalities for maintaining cadastral data by employees in mapping agencies and office management module which connects client requests for change of data or issuing the documents, with procedures in cadastre. The purpose of electronic services is to provide access to these registers to the citizens which can be natural or legal persons. Part of that data is available to all, while more data is available to registered users which are usually legal persons involved in legal issues, such as notaries, banks, ministry of internal affairs, tax administration etc. There are three types of services that are in use: eCadastre service, Web services for information systems of cooperative organizations and geoportal services. eCadastre service provides insight into land register and office management. Users are allowed to view data about rights over their properties. They can also view requests on properties and follow the execution of their requests. Issuing of documents and making request are provided for registered users. Cadastral Web services are intended for use by the information systems of other organizations that use cadastral data, as well as for the work of the eGoverment portal through which online services to clients are executed. Geoportal is established and maintained by the mapping agencies as part of the Spatial Data Infrastructure and provides view of layers of spatial data, including parcels and buildings. Finally, we make a discussion of possible directions of further development in cadastral domain in this region, based on 3D data acquisition technologies.
