Linear Referencing Tutorial

An overview of the linear referencing tutorial

ArcGIS has the tools you need for linear referencing applications. The easiest way to start learning about

linear referencing is to complete the exercises in this tutorial. Before you start, however, it is assumed you

know the fundamentals of ArcGIS software. For more information, see A quick tour of geoprocessing , A quick

tour of ArcCatalog , and A quick tour of editing .

For this tutorial, imagine that you work in the GIS department of a highway authority, responsible for the

maintenance and safety of your region’s highways. In the exercises to follow, you will perform some of the

linear referencing tasks typical to such a person. Specifically, you will use the linear referencing geoprocessing

tools to create and recalibrate route data. Next, you will learn how to display and query your newly created

route data, then your route event data, in ArcMap. Lastly, you will learn how to edit your route data in ArcMap.

This tutorial includes five exercises, each of which takes 5 to 30 minutes to complete. The exercises build on

one another, so it is assumed that you will complete them in order.

The study area for this tutorial is Pitt County, North Carolina. The data was compiled from various sources and

has been modified to suit the needs of the exercises. The reliability and suitability of the information, therefore,

cannot be guaranteed.

Linear Referencing Tutorial

Exercise 1: Organizing your linear referencing data in

ArcCatalog

The exercises in this chapter use the tutorial data distributed with ArcGIS

and work with an ArcView license. Some of these exercises require you to

make changes to the data; therefore, you will need to have write access to

the data. To be sure you have write access, you will begin this exercise by

making a working copy of the LinearReferencing tutorial folder.

Complexity:

Beginner

Data Requirement:

ArcGIS Tutorial Data Setup

Goal:

Organize the linear referencing tutorial

data in ArcCatalog.

Copying the data

Steps:

1. Start ArcCatalog by clicking Start > All Programs > ArcGIS > ArcCatalog 10.

2. Navigate to the LinearReferencing folder on the local drive where the tutorial data is

installed—for example, C:\arcgis\ArcTutor\LinearReferencing.

If the data was installed by your system administrator in a shared folder on the network, the

path to the tutorial folder includes the names of the computer and the connection through

which the folder is accessed—for example,

\\dataserver\public\ArcGIS\ArcTutor\LinearReferencing.

3. Right-click the LinearReferencing folder and click Copy .

4. Navigate to the location where you would like to make a copy of this data, such as the C drive.

5. Right-click this location and click Paste .

A new folder called LinearReferencing is created at this location.

6. Right-click this new folder and click Rename .

7. Type MyLR as the new folder name.

Connect directly to your tutorial data

In ArcCatalog, folder connections let you access specific directories on local disks or shared folders on the

network. Further, database connections allow you to access the contents of a database.

Steps:

1. Click the Connect To Folder button on the Standard toolbar.

2. Navigate to and choose the location of your MyLR folder.

3. Click OK .

The new folder connection is now listed in the Catalog tree.

You will now be able to access all the data needed for the remaining exercises in this tutorial via the new

connection.
