3D Analyst – Feature & Volumetric Analysis

Gert van Maren Jinwu Ma

July 24, 2012

• Introduction • Demonstrations

- Line-of-sight Analysis - Intervisibility Analysis - Sub-surface Analysis - Shadow Analysis

• Summary • Questions & Answers

Workshop Outline

3D Analyst Components • 3D Visualization Application Programs

- ArcScene - ArcGlobe

• 3D Analysis - GeoProcessing: - Surface Analysis - Conversions - Feature-oriented Analysis

- New at ArcGIS 10 with additions at 10.1

Introduction to 3D GeoProcessing

• Prepare data for visualization/analysis

• Performing surface/feature 3D analysis

• General GeoProcessing: - Batch/non-interactive data processing - Higher level functionalities over ArcObjects

Why 3D GeoProcessing?

• New toolset structure • 17 new tools added:

- Buffer3D - Difference3D - StackProfile - ObserverPoints - EncloseMultipatch - SunShadowVolume - Intersect3DLineWithMultipatch - And more LiDAR Dataset GP Tools…

What’s New at 10.1?
