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…
