CyberCity 3D, Inc.

• California based Company has been creating 3D GIS City Models for the past 7 years.

• Proprietary software utilizes automated photogrammetric techniques for best accuracy

– All roof features measured including substructures

– 3D GIS Data suitable for Shape File, PGDB, Multipatch, sketch up, etc.

– Can utilize current flight data off the shelf

• Esri Business Partner since Jan 2012

Who Benefits from 3D GIS Buildings• City planners and developers can visualize the impact of proposed

projects and share insights with community stakeholders. Zoning and new building views.

• GIS departments can realize more accurate building footprints for better base maps, facilities maps and other cartographic projects including 3D GIS.

• Sustainability planners can realize solar resource potential from 3D roof measurements and identify and analyze green roofs as well as visualize “green” buildings

• Facility managers can create and maintain building, infrastructure, and utility networks.

• Civil engineers can perform line-of-sight and shadow analyses for buildings, cell towers, and utility infrastructure.

• Police and security personnel gain more complete situational awareness.

• Military personnel can perform realistic mission and flight path analyses of planned deployments.

Key Aspects of the Spatial Database

• Spatial Measurements: Finds the distance between points, polygon area, etc.

• Spatial Functions: Modify existing features to create new ones, for example by providing a buffer around them, intersecting features, etc.

• Spatial Predicates: Allows true/false queries such as 'is there a residence located within a mile of the area we are planning to build the landfill?'

• Constructor Functions: Creates new features with an SQL query specifying the vertices (points of nodes) which can make up lines. If the first and last vertex of a line are identical the feature can also be of the type polygon (a closed line).

• Observer Functions: Queries which return specific information about a feature such as the location of the center of a circle

Real 3D GIS Data includes Feature Classes

The Skyline Tool (part of 3D Analyst)Generates a 3D polyline representing the line that divides the sky from the surface and/or features that touch the sky, based

from the perspective of the observer location. An observer point; a functional or virtual surface; a range (from and to) of azimuths; and, optionally, features (which typically represent buildings) are added as input.

Example: Skyline Tool

The Line of Site Tool (part of 3D Analyst)The Line Of Sight tool calculates intervisibility between pairs of points given their position in 3D space and relative to a surface or

features. It also determines what is visible along the lines between these points as they are profiled on the surface.

Example: Line of Site Tool
