Developement and Implementation of Land Information System using new Technologies Information technologies as a crucial means for supporting decentralization of land administration

LandNetwork doc: LIS 2

Initial situation and challenges

Land Information Systems (LIS), tailored to the needs and objectives of public administration, enable independent management of data and guarantee its availability for a variety of public services and the private sector. LIS thus support the objectives of decentralization and provide an effective instrument for the efficient management of the land resources. In developing and implementing LIS, LandNetwork bases its work on the following three principles:

• The Principle of Single Responsibility: the idea is that the collection, maintenance, updating and publication of land information of a certain topic falls, in accordance with the concerned legislation, within the competence of a single authority and that the data concerned can therefore only be managed by that authority.

• The Single Point of Truth-Principle, according to which a dataset about a certain topic must be in only one place and that place is related to the authority responsible of the dataset.

• The Principle of Legal Independence, according to which an information topic resulting from a particular legislation should be independent from other legislations.

From Blockchain to Augmented Reality and Deep Learning to the use of drones and GNSS – new technologies support the accomplishment of tasks in land administration Blockchain is a technology that guarantees the truthfulness of a dataset (block), based on other blocks that precede it. The relocation of the different blocks guarantees their security and, together with the use of encryption technologies, their inviolability. The blockchain technology can be applied in cadastre, land registers and other parts of land administration to create efficient procedures to ensure, for example, the truthfulness of a land title taking into account its transaction history.

• Augmented Reality consists of displaying objects from a database (georeferenced) in addition to the reality observed through a screen or digital lenses (such as HoloLens®), thus increasing the context of the visualized environment. LandNetwork is active in integrating AR technology into the needs of land administration and cooperates with universities and technology partners for this purpose.

• RPA (Remotely Piloted Aircraft) and RPAS (remotely piloted aircraft systems), enables the acquisition of high-resolution and high-quality geo-information to meet the requirements of specific land administration operations.

• Global Satellite Navigation Systems (GNSS) receivers provide high accuracy and reliability in measuring discrete point coordinates (boundary vertices and control points) by applying the differential method, especially when the correction data is obtained in real time (RTK). In extensive work areas, establishing continuously operating reference stations (CORS) is convenient. The coordinates of such stations should then be integrated in a geodetic reference frame of higher order (e.g. ITRF, ETRF, SIRGAS). The RTK correction data is ideally transmitted via GPRS. In areas without CORS networks and without reliable communication systems, satellite signal transmitted correction services can provide worldwide centimeter level positioning accuracy in real time (depending on the chosen service)

• Methods of deep and machine learning for the automated detection of objects in digital ortoimages are used more and more in the asisted delimitation of visible boundaries, especially where a general boundary approach is applied and high perfomance but low accuracy is requiered. Different open source and proprietary tools exist and can be taylored to the processes and projects where employed.

How do we support? LandNetwork has extensive experience in LIS with a proven track record in the design, development, implementation and management of such systems, including::

• Deployment in Client-Server environments • The application of geodata infrastructure (SDI)

concepts with the aim of ensuring the above-mentioned principles as well as the principles of publicity and interoperability

• The use of international standards for efficient data management (e.g. ISO19152 - LADM, etc.)

• The use of OGC and other standards for web geoservices and modell-based data exchange

LandNetwork actively promotes the use of Free and Open Source Software (FOSS) although proprietary software is also used on request by our clients. In any case, training of technicians responsible for the use and administration of the LIS is a key element for system sustainability

LandNetwork offers its experience here and in the other mentioned technologies, e.g. in deciding on the most suitable method, software or equipment according to the respective project requirements. This includes the elaboration of technical specifications and the execution of studies and technical concepts
