Planners can analyze where the proposed building is casting new shadows, window by window, by time of day. Tools built into the ArcGIS 3D Analyst extension help users assess the visual sensitivity of a proposed project or building, including changes to a skyline, effects of shadow on existing structures, and impacts on viewsheds and lines of sight for surrounding buildings. Concepts can be quickly visualized, evaluated, refined, or tossed aside depending on how a scenario plays out. The real power of ArcGIS 3D virtual cities comes in evaluating what-if scenarios. There's also a tutorial on performing different types of 3D analysis.

The Virtual City template uses Philadelphia, Pennsylvania, as a best practices model, walking users through step-by-step instructions on how to add elements to create a virtual city. Included template features of street furniture, vegetation, cars, and people seem to bring virtual cities to life.Ī temporal element is added to create a window-by-window shadow analysis.
The virtual city model can also go belowground to include subsurface structures, such as basements, parking structures, subway systems, and utility infrastructure. To speed the transition to planning cities and communities in 3D, the ArcGIS 3D Analyst extension now includes a Virtual City template.Ī realistic 3D city model combines basemaps imagery elevation information and objects, such as buildings and bridges.

With the release of ArcGIS 10 and significant capabilities added to the ArcGIS 3D Analyst extension, the system becomes a truly 3D GIS.
