ArcGIS for land records : current status and future 3D considerations
Bjorsson, Carsten & Nick Land
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. Using the ArcGIS parcel fabric model, allows for the legal boundary definition of parcels while at the same time maintaining the topologic relationship between parcels and to other spatial objects. By representing multi floored buildings each containing one or many parcels, overlapping parcels topologies can be maintained through least squares adjustments and joins. Overlapping polygons can be represented as 3D objects in ArcGIS allowing for identification, search, analysis and visualization of parcels. The paper also highlights some additional capabilities within ArcGIS for extending the use and value of 3-D cadastral data in related areas such as city planning, design of new buildings and minimizing environmental impact.
