Getting Started with Linear Referencing (for ArcGIS 10)

Description

Linear referencing is a method of storing data that adds a new dimension to line features. By storing distance or temporal measures at relative positions along a line, you extend the ability to visualize and analyze phenomena associated with features such as roads, pipelines, and streams. In this course, you will learn essential concepts of linear referencing and how to create and edit the data required for linear referencing-based mapping and analysis.

Who Should Attend

GIS specialists, data technicians, data managers, and other professionals who need to model events and attributes associated with line features. Analysts working in the transportation, water resources, utilities, and pipeline industries may find the course of particular benefit.

Learn How To

• Describe the elements required for linear referencing.
• Create a route feature class from existing line features and from scratch.
• Assign a suitable measurement system to a route and calculate measure values.
• Create and edit event tables to store information about assets, conditions, and events that occur at specific locations along a route.
• Symbolize route events so they are easily distinguishable on a map.

To complete course exercises, you need the following software:

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

Understanding linear referencing
