What is 3D GIS? • Main trouble of most of current 3D visualizations? Semantically rich 3D GIS • Respect 2D GIS concepts: – (geographic) data base – Cartographic aspect – Analytical aspect • Hence in 3D: – Connection to existing attribute databases – Composed of (1D, 2D, 2.5 and 3D data) – Using (and evolving) 3D cartography – 3D analytical tools 3D GIS – a Case Study in Cultural Heritage • Motivation : – Curators of castles and chateaux are looking for a data model which would allow more detailed registers than existing national model (paGIS) and national register (IISPP). • Project goal: – Create a comprehensive geographic data model suitable for database management of information about an areal of a castle or chateau. 3D GIS – a Case Study in Cultural Heritage • Conception – Cultural heritage has to be: • • • • both protected and publicly accessed, well identified and registered, maintained and restored, managed and presented. – Thus it is necessary to find a unifying tool : • (3D) GIS linking to existing registers 3D GIS – a Case Study in Cultural Heritage • User requirements – basic: – The model has to be compatible to national 1D/2D data model paGIS. – The model has to allow access to geographic data in different ways: 1D 2D 2,5D 3D 3D GIS – a Case Study in Cultural Heritage • User requirements in detail: 1. 2. 3. 4. 5. Interoperability to national systems Smooth transition Openness and future expandability Completeness and sufficient detail Awareness of a spatial threshold: a) b) c) Full-valued (3D) representation of the object shape (and a 2D footprint for purposes of 2D management). Point representation of object’s position. Indirect spatial representation. 6. Hybrid 2D / 3D access. 3D GIS – a Case Study in Cultural Heritage • Conception of areal passport – Decomposition: • Areal boundaries identification. • Areal division into sub-elements. • Divison to immovables and movables. – Building division. – Movables portrayed in map: » by their shape, » by their reference point, » by the reference 3D GIS – a Case Study in Cultural Heritage • Decomposition: – areal and its boundaries, – exterior sub-elements, –… 3D GIS – a Case Study in Cultural Heritage 3D GIS – a Case Study in Cultural Heritage 3D GIS – a Case Study in Cultural Heritage Room Chapel- sacral part Chapel- sacral part Chapel- sacral part Chapel- sacral part Chapel- sacral part Chapel- sacral part Chapel- sacral part Chapel- sacral part Chapel- sacral part Chapel- sacral part Chapel- sacral part ….
