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
