3D Analysis of Surfaces and Features Using ArcGIS 10

Description

Some geographic questions can be answered only in 3D. Using 3D analysis tools, you can perform complex calculations and create sophisticated models that take terrain, elevation, and 3D features such as buildings into account. In this course, you will go beyond simple 3D visualizations as you work with a variety of 3D analysis tools to solve problems and create information that can't be obtained in 2D.

Who Should Attend

GIS analysts, urban planners, hydrologists, mining geoscientists, emergency planners, geospatial intelligence analysts, and other experienced ArcGIS users who need to:

• Visualize the impact of proposed projects on existing features.
• Find suitable locations for buildings, utility infrastructure, and cell towers.
• Analyze potential security risks.
• Model surface and subsurface terrain and calculate volumes.
• Create models to support disaster response and mitigation.

Learn How To

• Create sight lines to determine what can be seen from different observation points and analyze visibility along a line.
• Create skylines and skyline barriers to analyze the visual impact of proposed features on a cityscape or scenic view.
• Determine maximum feature height required to preserve visibility between specific locations across a terrain.
• Determine the steepest path down a surface to model things such as runoff, drainage patterns, and trail difficulty.
• Create a profile graph to quickly visualize elevation changes along a steepest path.
• Calculate 2D and 3D surface area and volume, above and below a plane.
• Calculate volumetric differences between two surfaces to detect and quantify change.

To complete course exercises, you need the following software:

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

Determining line of sight
