Abstract
The world is facing serious challenges including global climate change, aging infrastructure, a shrinking workforce, and lagging productivity. To enable architects, engineers, construction companies, and owners and operators of buildings and infrastructure address these challenges, new technologies are being applied including geospatial-enabling, building information modellng (BIM), Web 2.0 collaboration, and 3D visualization and simulation. The business drivers for this transformative technology advance are productivity and efficiency in the $4.6 trillion construction and facilities management industry, and improving the performance of facilities over their full life-cycle. But these new technologies are not only changing how we design, manage, and operate buildings and infrastructure, but enable intelligent 3D precision simulation of urban environments. In the past, 3D urban modeling was generally difficult requiring sophisticated modeling skills, as well as being expensive, and was only undertaken by the largest urban municipalities. Technical advances are now making 3D urban modeling available to a much broader market including municipalities which may have felt in the past that 3D urban modeling was out of their reach. New software tools and applications are making it possible for a much broader range of users to create and deploy 3D urban models to the desktop and across the web.
