3D Visualization Techniques Using ArcGIS 10

Description

Viewing data in 3D allows you to detect patterns and trends that aren't always apparent in 2D. A 3D perspective creates a realistic simulation of a project, environment, or critical situation to help you plan, prepare, and proactively mitigate potential issues. This course introduces fundamental concepts of 3D visualization, including the types of data that can be used in ArcGIS 3D Analyst and techniques to display both spatial and nonspatial data in 3D.

Who Should Attend

GIS analysts, planning professionals, mining geoscientists, geospatial intelligence analysts, and other experienced ArcGIS users who need to learn fundamental concepts of 3D GIS.

Learn How To

• Explore vector and raster data in a 3D perspective using ArcScene and ArcGlobe navigation tools.
• Understand what makes data 3D.
• Display 2D features in 3D.
• Enhance the 3D display of your data using illumination and vertical exaggeration tools.
• Convert 2D features to 3D multipatch features.

To complete course exercises, you need the following software:

• ArcGIS 10.0 for Desktop (ArcView, ArcEditor, or ArcInfo)
• ArcGIS 10.0 3D Analyst

Data used for 3D visualization

• Z-values
• Raster data
• Triangulated irregular networks (TINs)
• Terrain datasets
• Multipatch features
• 3D features
• 3D navigation basics
• Identify data types

Techniques for defining base heights

• Base heights
• Set base heights for raster and feature data (ArcScene)
• Set roles for 3D layers (ArcGlobe)

Techniques for enhancing 3D views

• Enhancing 3D scenes within ArcScene
• Vertical exaggeration
• Illumination
• Set vertical exaggeration (ArcScene)
• Set illumination and background color (ArcScene)

Generating 3D objects from 2D features

• Extrusion
• Extrude buildings and wells (ArcScene)
• Extrude parcel values (ArcScene)
• Extrude buildings (ArcGlobe)

Completion of Learning ArcGIS Desktop or equivalent knowledge is required.
