Linear Referencing with ArcGIS Desktop

Description

ArcGIS Desktop software supports linear referencing, a method of storing data that adds a new dimension to line features. Linear referencing extends the ability to visualize and analyze linear features such as roads, pipelines, and streams. Instead of relying solely on x,y coordinate geometry, linear referencing is based on relative positions along the line using distance or temporal measures, like miles or hours. For example, an accident that occurred at a specific milepost on a highway could be modeled with linear referencing. This course covers how to generate and display linearly referenced features in a map as well as how to incorporate them into GIS analysis.

Who Should Attend

This course is designed for experienced ArcGIS users who want an introduction to linear referencing.

Learn How To

• Create simple routes from existing line features.
• Assign measures to routes.
• Query routes.
• Symbolize routes with hatching.
• Create a route feature class.
• Edit route features and remeasure them.
• Calibrate route measures.
• Create and overlay event tables.
• Generate route events.
• Create and edit complex routes.
• Transform route events from one measurement system to another.
• Use additional analysis techniques.

To complete course exercises, you need the following software:

• ArcGIS 9.1 for Desktop, ArcGIS 9.2 for Desktop, or ArcGIS 9.3 for Desktop (ArcView, ArcEditor, or ArcInfo)

• Introducing Linear Referencing: Routes; Symbolizing routes
• Working with Linear Referencing: Route events; Editing routes; Adding complexity to routes
• Linear Referencing Analysis: Analyzing events

Students should have completed Learning ArcGIS Desktop and Creating, Editing, and Managing Geodatabases for ArcGIS Desktop or have equivalent knowledge.
