Working with 3D in 10.1 Kevin Armstrong
Agenda
• Working with LiDAR in ArcGIS - Terrain dataset - LAS Dataset - Mosaic Dataset
• Demo - LAS Dataset • 3D Design • Demo - City Engine
Types of lidar
• Airborne - Captured from aircraft - Suitable for surface analysis
• Terrestrial
- Captured from the ground - Suitable for feature location and data validation
ArcGIS Versions
• Current release - 10.0 - Support for Lidar includes Terrain, Mosaic dataset
• Upcoming release - 10.1 (June 2012) - New data-type being added – LAS Dataset
Terrain Dataset
• Multi-resolution surface • Typical applications
- Topographic mapping - Bathymetric mapping
• Typical data sources - Lidar - Photogrammetry - Multibeam Sonar
Terrain Benefits
• Scalability • Data Integration • Database oriented solution
LAS Dataset
• New data type • File based • Stores references to LAS files on disk • Optionally reference constraints such as breakline
data • Treats a collection of LAS files as one logical dataset
Project Workflow in ArcGIS 10.1
LAS files LAS Dataset
• Direct access to LAS • Create LAS Dataset
- Catalog of LAS files for a project
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
LAS Dataset - Editing
• Manual editing (data errors, mis-classifications)
• Using Geo – processing tools
LAS Dataset
Analysis of lidar as a surface
• Define the surface… - Filter the lidar points based
on lidar attributes
- Improve the surface
using constraint features
• Run GIS analysis against it… - Contours, Slope, Aspect, … - Surface differences
Available GP Tools
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
Multiple Elevation Data Sources
Web Mobile Desktop
Mosaic Dataset
Constraints
LAS files LAS Dataset Terrains Raster grids
• Catalog of data sources • Contains metadata • Defines processing • Serve to many applications
Dissemination
Usage Recommendations
• Most suitable for working with airborne Lidar data • Classified LAS files organized as ‘tiles’ • All participating LAS files with the same Spatial
Reference (Projected Coordinate System) • Project-based / Localized in scope • Data on a local disk
City Engine
Introduction to CityEngine 3D modeling and design solution
• What is Esri CityEngine?
• Current markets
• Product positioning
• Integration with ArcGIS
Makes it easier to create and design in 3D
Esri CityEngine 3D procedural modeling and design solution
- 3D Content - Model cities in 3D using
parametric rules
- 3D Design - Rule driven design in 3D
Rule based 3D content and design
Geometry + Attributes + Rules
Dynamic + Parametric editing
Procedural modeling vs. Manual modeling
Time reduction / cost saving
