Collaborative decision making

Less subjective

Greater inclusion / transparency

Planning for disabled access

Brunnhuber (2007)

Public only interested in geovizualization, not the data model and analysis

Professional users

Expert users

Improved decision making?

Improved visual output

Non-expert business users

User-friendly - more engaging

May be competitive market for GIS plug-ins etc

Challenges of interoperability, with CAD, Akinci (2009)

Challenges of interface design, Bistrom(2005)

Data collection

Laser scanning

In geology - Buckley (2009)

In urban environments - Overby (2004)

Data model

Relational databases (RDBS) unsuited

Object-oriented databases (OODBMS) better

Zlatanova (2002), Constructive Solid Geometry, origins in CAD, Built from primitive shapes (spheres, squares etc), Can become complex, Voxels - tesselation representation, Similar to raster but in 3D, Large volume - like raster data but exponentially larger, Tetrahedrons, Forms all shapes from one 3D primitive shape, Can take many tetrahedra to create one shape, Relatively easy to work with, Boundery representation, Shapes formed of points, lines, polygons and polyhedrons, Can become complex


More complex topology
