Esri International User Conference San Diego California Technical

Esri International User Conference San Diego, California Technical Workshops | July 24, 2012 3 D Analyst – Feature & Volumetric Analysis Gert van Maren Jinwu Ma

Workshop Outline • Introduction • Demonstrations Line-of-sight Analysis - Intervisibility Analysis - Sub-surface Analysis - Shadow Analysis - • Summary • Questions & Answers

Introduction to 3 D Geo. Processing 3 D Analyst Components • 3 D Visualization Application Programs - • Arc. Scene Arc. Globe 3 D Analysis - Geo. Processing: - Surface Analysis Conversions Feature-oriented Analysis - New at Arc. GIS 10 with additions at 10. 1

Why 3 D Geo. Processing? • Prepare data for visualization/analysis • Performing surface/feature 3 D analysis • General Geo. Processing: - Batch/non-interactive data processing - Higher level functionalities over Arc. Objects

What’s New at 10. 1? • New toolset structure • 17 new tools added: - Buffer 3 D - Difference 3 D - Stack. Profile - Observer. Points - Enclose. Multipatch - Sun. Shadow. Volume - Intersect 3 DLine. With. Multipatch - And more Li. DAR Dataset GP Tools…
