article landxplorer urban utility network already exists in precision digital form, in the form of cad drawing files, bim models, utility and telecommunication network infrastructure databases, and geospatial data. the objective is to re-use the precision data that was created when a facility is designed. this involves integrating precision engineering data to deliver a precise synthetic environment that can be used to simulate the inside (utilities, hvac systems, furniture, elevators, walls, doors, windows, and structural details), outside (aerial utilities, full city blocks of 3d detail, road access), and under (underground water, wastewater, gas, power, and telecommunications systems) of an urban environment and to make this available in a seamless, easy-to-use, interactive model familiar to digital gamers that allows the user to visualize and analyze all aspects of the facility, inside, outside, and underneath. reduces the risk of major modifications to built structures, and enables optimization of buildings and infrastructure for their full lifecycle including operations and maintenance. 3d visualization technology enables stakeholders to experience a building or structure during the desing phase before it is constructed. it enables integrating building information modeling (bim) data, scene elements from multiple applications, real-time sun and sky, vegetation and simulated people and vehicles from an integrated content library. it gives designers an instant, high-fidelity visual validation reference and allows the addition of narrative to designs with camera animations and walkthroughs to help communicate the proposed design to stake holders. convergence enables sustainable digital infrastructure convergence refers to the integration of these key technologies including model driven design, geospatial enabling, and 3d simulation and provides a high quality visual environment and analytical framework that enables seamless access to architectural and engineering design, traditional gis, new data sources such as laser scanning and high resolution photogrammetry, and transportation, utility, and telecommunications network data inside, outside, and under a facility. convergence breaks down the barriers between architectural design, engineering, land development, civil engineering, construction, geospatial disciplines, and 3d visualization and simulation technology. convergence provides a framework of interoperability across the lifecycle of building and infrastructure investment involving design, construction, and operation. it also enables seamless access to architectural, engineering design, and geospatial data inside, outside, and under a facility. the data that is required for a seamless view of an urban environment sustainable design by creating interoperability between different disciplines, we are creating a much more holistic view of the built world that not only look realistic but offer the depth of information required to do meaningful sustainability analyses. one discipline that is seeing incredible growth right now is sustainable design, at a building level or a city level. by being able to bring people together from different disciplines and create a seamless digital environment for sustainable design would not have been possible in the past, when architects, civil engineers, and utility designers had to work within non-interoperable technology silos. this means that these new technologies are not only changing how we design, build, and operate and manage buildings and infrastructure, but are enabling the intelligent 3d precision simulation of entire urban environments. the data that is required for a new york port authority 54 june 2009
