Joint ISO/TC211 and OGC Revision of the LADM: Valuation Information, Spatial Planning Information, SDG Land Indicators, Refined Survey Model, Links to BIM, Support of LA Processes, Technical Encodings, and Much More on Their Way!

ISO standards, which are actually being applied, are subject to periodic revision, typically in a 6 to 10-year cycle. A UN-GGIM Meeting of the Expert Group on Land Administration and Management was held on 14-15 March 2017, in Delft and the main conclusion was that the revision of LADM was indeed needed in order to provide better tools to...

Towards an Implementable Data Schema for 4D/5D Cadastre Including Bi-Temporal Support

Cadastral databases have unique requirements not shared by other spatial databases: The third spatial dimension must be included, but visualisation using 2D software must also be accommodated. The majority of users of the Cadastre will use 2D software, and should be provided an “instant in time” plan view of the boundaries (with any 3D parcels ...

A Roadmap to Accomplish 3D Cadastres

Urbanisation is regarded as a significant global trend. This means cities around the world will be accommodating more population. The population demands accommodations as places for living and business activities. Cities have limited land and therefore high-rise structures have become major infrastructures addressing the needs arsing from...

ArcGIS for Land Records: Current Status and Future 3D Considerations

3D cadastre is necessary to display and manage complex spatial relationships. To support a full 3D cadastral implementation, object boundary definitions, object topologies and their legal representations will have to be further defined. A hybrid approach combining 2D and 3D using GIS represents a feasible, economical and extensible approach....
