03-11: Interoperability of land data: Conceptual issues
Land administration data integration – modern concept
Innola Solutions, Inc., United States of America
Building a national scale land administration system inevitably depends upon existing data digitization, migration and ultimately, integration of the digitized data into the system as a pre-requisite of the system rollout. Separating data digitization from system implementation makes it easier to early start the data production processes using different available tools - mainly serving specific needs such as scanning, indexing and maps digitization. However, the real content of the land administration records requires a more complicated data structure and, accordingly, more elaborate technologies to ensure the quality, completeness, sequence and integrity of the produced digital data. Based on the experience gained in several national-scale projects, the authors describe a holistic “top-down” approach of data digitization and acquisition. Modern concept is in evaluation of different data sources from a prospective of the future services and system functions, and defining a clear schema of how those various data are going to be integrated.
Land Administration Models - A central register and land information system containing as much information as possible about a property
HM Land Registry, United Kingdom
We review the benefits of centralised land information and registration systems, defined as an integrated land information system, where formal registration of legal information as well as technical information about land is supervised, controlled and operated by one authority, so that all matters affecting one parcel of land can be easily accessed.
Land registration and cadastral functions are more effective under a centralised system. Decentralisation of land administration may help to develop local democracy and skills, but in the longer run could hold back progress. Local conditions may mean that it is difficult to implement a centralised system and innovative decentralised solutions may help in the short term. However, improvement of a centralised system is likely to be more advantageous in the long term than developing a decentralised model where there is a risk of introducing or perpetuating a fragmented system of land registration and land information.
An applicative approach for cadastral processes implementation in multi-dimensional land management systems
Mapping and Geo-Information Engineering, Technion - Israel Institute of Technology, Israel
The world’s population is expected to reach 9.7 billion in 2050, 66% of them will live in urban areas, resulting in the crucial need for multi-dimensional cadastral systems that are required for an efficient management of the urban space. Our study aims at setting an approach for augmenting existing 2D cadastral systems to multi-dimensional ones. The full integration of the height, time and scale dimensions, including all topological aspects within the same system, will prevent the need of handling management and functional properties in segregated systems to support decision-making and multi-purpose applications, as well as providing the opportunity of sharing geo-data by diverse users. A simulation of planning a new 3D project in a complex urban environment, offering functionalities and data model for performing complex 3D analysis and editing, is presented. Our solution is a first step towards the implementation of multi-dimensional cadastral systems.
The impact of the agricultural land management information system on the work of local self-government units and directorate for agricultural land
GIZ- Deutsche Gesellschaft für Internationale Zusammenarbeit, United States of America
This Impact Study assesses the impact the IT-solution for the management of state-owned agricultural land has had on the work of municipalities and the Directorate for Agricultural Land in Serbia. It analyzes the biggest changes the system brought to the local and national level, as well as the influence it had on the end beneficiaries. Data was collected from three sources: document analysis, semi-structured individual interviews, and an online questionnaire sent to all 145 municipalities. Analysis of all data shows that DAL and municipal officials are spending significantly less time creating Annual Programs and Contracts. They are printing, filing, and mailing many fewer documents, all while increasing transparency in a previously opaque system. There are already measurable improvements in the quality of products from the new IT system. There is evidence that customer service will be enhanced and communications among DAL, municipalities, and clients is easier and clearer.
