This Autodesk press release reminded me of attending a conference in Korea back in 2006. At that stage it was more about BIM and the new Songdo City, currently in construction. The next logical step after BIM is aggregating them in Digital City models. It seems Korea wants to be at the forefront of that with Incheon joining Songdo to be their second Digital City Model.
Maybe the new "Auckland Super City", a proposed amalgamation of several local bodies, should focus on building a digital city infrastructure model? Auckland doesn't have a huge population (~1.4 Million) but covers a large area. With infrastructure management rationalisation being one of the justifications for the change why not do it properly?
