Big5 Geospatial Challenges to Geo Enable BIM Level 2Generalisation – Action Who/What first ?

Priorities for call to action

1. Collate available standards from Industry and Professional organisations and BIM software vendors on how they currently support generalisation

2. Identify and engage 3D specialists outside of the direct construction community who specialise in generalising data for visualisation, gaming etc……

3. Determine use cases and examples of outputs generalized for user benefit – and end user services – (interpretable, safe decisions, good service- branding of generalised services (which may be products but may be broader)
