4 Federal Office of Topography swisstopo Federal Directorate for Cadastral Surveying Daniel Steudler, 8 May 2013 Challenges – Environmental sustainability environmental sustainability is hugely affected by the "tragedy of commons" dilemma; serious erosion and degradation problems;  clear definition of responsibility and accountability for the resource "land".

5 Federal Office of Topography swisstopo Federal Directorate for Cadastral Surveying Daniel Steudler, 8 May 2013 Challenge – Disaster management Thailand after tsunami: lack of proper landownership information allowed financial investors to take over land, while local fisherman have been ousted from their properties; well documented landownership information would have protected minorities with lesser economic power against exploitation; Aceh after tsunami: the loss of land registry and cadastral data caused huge problems for reconstruction, planning, and social stability;  Disaster management starts before the disaster; landownership information is crucial.

6 Federal Office of Topography swisstopo Federal Directorate for Cadastral Surveying Daniel Steudler, 8 May 2013 Challenge – Land Management Nail house in Chongqing, China (2007): A cadastre with documentation of land ownership is clearly in place, but something else seems to be non-satisfactory.

Rajabifard, editors, 72 pages, FIG Publication no. 58  Publication «Spatially Enabled Society» A spatially enabled society – including its government – is one that makes use and benefits from a wide array of spatial data, information, and services as a mean to organize its land related activities. Spatial enablement is a concept that adds location to existing information and thereby unlocks the wealth of existing knowledge about the land, its legal and economical situation, its resources, potential use and hazards. Information on landownership is thereby a basic and crucial component to allow for correct decision-making. Such data and information must be available in a free, efficient, and comprehensive way in order to support the sustainable development of society. It therefore needs to be organized in such a way that it can easily be shared, integrated, and analysed to provide the basis for value-added services.

9 Federal Office of Topography swisstopo Federal Directorate for Cadastral Surveying Daniel Steudler, 8 May 2013 Six Key Elements for a SES Legal framework for basic geoinformation; Common Data integration concept legal and institutional independence of information (to allow for independent responsibilities); common geodetic reference framework; standardized data modelling concept; Positioning infrastructure for the common reference framework; Network infrastructure to enable integration and sharing of spatial data through the spatial data infrastructure SDI; Landownership information as one of the basic information topics; Data and information official, authentic, complete, comprehensive, updated; accessibility of data i.e. public sector information initiatives; volunteered geographic information (VGI), web 2.0 possibilities.

11 Federal Office of Topography swisstopo Federal Directorate for Cadastral Surveying Daniel Steudler, 8 May 2013 Land Ownership Information application of subsidiary principle: political decisions should be taken at lowest administrative and political level, and as close to the citizens as possible interaction between Government, business, and citizens is concerned with land tenure, land tenure security, land and mortgage market it is generally accepted that a land administra- tion system is to be based on land ownership data examples are INSPIRE (where cadastral parcel is a core data set); the six Dutch official and authentic registries (one of them "parcel and land registration"); or the Danish basic data program (person, business, real property, address, geographic, and incomes data) Paul van der Molen

14 Federal Office of Topography swisstopo Federal Directorate for Cadastral Surveying Daniel Steudler, 8 May 2013 Common Data Integration Concept GDI can be operated independently from other stakeholders layers/domains can be added or removed as the need arises layers/domains can be used to manage and accommodate different legal or social issues (e.g. private landownership vs. traditional indigenous land tenure; crowd-sourced data; VGI; etc.) local, national or regional GDI can be established, which can share and aggregate data sets for the benefit of sustainable governance Advantages (2/2)

15 Federal Office of Topography swisstopo Federal Directorate for Cadastral Surveying Daniel Steudler, 8 May 2013 Common Data Integration Concept all stakeholders have to respect those basic principles and maintain and update their data sets accordingly setting-up a GDI is less of a technical problem, it is much more about inter-governmental communication (to overcome stakeholder's silo-type of thinking and the fear of loosing control over its own data and information) Issues

16 Federal Office of Topography swisstopo Federal Directorate for Cadastral Surveying Daniel Steudler, 8 May 2013 Conceptual Principles to Ensure Inter- operability in Land Administration 1)legal and institutional independence, “layer” principle (possibi- lity to define independent stakeholder responsibilities); 2)common geodetic framework; 3)standardized data modelling concept (long-term data security); 4)no logic relations between domains (connection through geographic location only); 5)mandate for an independent body to operate the GDI, in order to avoid power games between agencies. These principles allow for an independent, very responsive, and rather flexible geodata infrastructure (GDI).

17 Federal Office of Topography swisstopo Federal Directorate for Cadastral Surveying Daniel Steudler, 8 May 2013 Case Study Switzerland 1994: definition and introduction of digital format in cadastral surveying (with 8 information domains and standardized data modelling concept); 2004: adapted data model for cadastral surveying with 3 additional information domains; since 2009: development of GDI independently from cadastral surveying; includes today some 150 different information layers/domains (see map.geo.admin.ch); 2012: decision to include additional 17 public-law restrictions (=domains) from different stakeholders into the cadastre in order to provide an integrated and more transparent picture of private- law (rights) and public-law (restrictions) issues related to land;  such developments – mainly also in a federated context – are possible only by respecting the basic conceptual principles for land administration.
