Prepare data for visualization/analysis Performing surface/feature 3D analysis General GeoProcessing:
Batch/non-interactive data processingHigher level functions over ArcObjects
-
Line of Sight
How much of the road can be seen from these camera / observer locations?
Quick assessment of visibility between features using geo-processing tools.
-
Line of Sight
How much of the sky is obstructed by this proposed building? Does it violate our planning ordinances?
Summarized assessment of % of viewable sky, based on line of sight tools.
-
Cumulative Line of Sight
How visible are these buildings to the surrounding area?
Cumulative line of sight analysis, with visual prominence / quality.

Skyline and Skyline Barrier
Which buildings define our skyline? How high can we build without changing our skyline?
Intersect sample points with a surface created using skyline barrier, then using it to generate a buildable volume.
-
Intervisibility
Line of sight
Demo: Sky occlusion
-
Shadows and shadow maps
Where do shadows fall? How can we quantify their impact over time?
Intersection of shadows, at specified time intervals, for specified days in the year, on a park polygon.
-
Glare estimation
Where, roughly, will sun reflected off this proposed building fall.
3D intersection to extract faces in shade, then skyline volumes are used to simulate light volumes.

Built Environment
Created and actively managed by peopleStructures, utilities, transportation networks, installations
Legal Environment
Defines restrictions on land useLand use zones, property ownership boundaries, regulations
Natural Environment
Naturally features on, above, or below the surfaceLand cover, subsurface geology, atmosphere/climate/weather
The 3D City Information Model simplifies the creation, maintenance and usage of 3D cities.
