2. Topics:
What’s new: Sensors & Software
What does 3D do different
3D analysis

3. Sensors

6. Working with lidar in a GIS
• Same four elements as with any GIS work
Visualize Update
Share Analyze

7. Viewing lidar
• In 2D (ArcMap) or 3D (ArcScene)…
• As points
• Symbolize using LAS attributes
(Class Codes, RGB, Scan Angle, etc)
• As a surface
• Symbolize & filter using surface options
(Bare-earth, First-return, etc)
• Control the number of points shown
• Full resolution in a local area

8. Update / edit lidar class codes
• Manually…
– Fix data errors, small areas
• Via the API…
– Using algorithms, large areas
• Support feature or surface extraction

9. Management and sharing
• Manage lidar like imagery
via Mosaic Datasets
– Add / remove LAS files
– Add / remove LAS datasets
• Share the data as Image services
– Easy for others to see available lidar
– Easy to download for project work

13. Software

15. Esri CityEngine
3D procedural modeling and design solution
3D Content
• Model cities in 3D using
parametric rules
Geometry + Attributes + Rules
3D Design
• Rule driven design in 3D
Dynamic + Parametric
editing
Rule based 3D content and design

16. CityEngine is for..
Procedural modeling and design solution
– 3D urban content creator
• 3D cities from existing GIS data
(Geometry + Attributes + Rules)
Not as-built -> approximation
– 3D design tool
• Rule based design of 3D cities
Using planning regulations etc
Rule based 3D content and design

17. Procedural
3D geometries and textures are constructed using rules
(procedures) instead of labor-intensive manual modeling.
A single procedural rule can be used to generate many 3D
models.
Called CGA(Computer Generated Architecture) rule files in
CityEngine.

18. Procedural modeling vs. Manual modeling
Time reduction / cost saving

19. Streets and Lots
Street Generator engine and edit tools
Many parameters for
automated generation
Imported Single line vector
exploded to multiple street
entities

20. Geo-Specific and Geo-Typical
Types of 3d buildings
Geo-Specific Geo-Typical
Cathedral Basilica of Saints Peter and Paul Afghanistan Style Geo-Typical
Philadelphia, PA

21. Geo-Specific Buildings
Buildings that look realistic
Photorealistic, Photo textured
Pictometry models and other vendors
Imported from any of the supported formats
Collada(dae), DXF, KML/KMZ, OBJ
Export Multipatches to Collada for CityEngine
import

22. Geo-Typical Buildings
Buildings that represent the style or look of a location
Imported from the geodatabase, other formats
or generated by the procedure engine
Realism is driven by attributes
May change gdb design to capture additional
details
May not have textures(buildings rendered
thematically)

23. Data Availability
