Network Analyst Tutorial

About the ArcGIS Network Analyst tutorial

The ArcGIS Network Analyst extension allows you to build a network dataset and perform analyses on a

network dataset. The best way to learn Network Analyst is to use it. In the exercises in this tutorial, you will do

the following:

• Use ArcCatalog to create and build a network dataset from feature classes stored within a

geodatabase.

• Define connectivity rules and network attributes for the network dataset.

• Perform various network analyses in ArcMap using the Network Analyst toolbar.

• Learn how to use the Network Analyst geoprocessing tools to create models that automate analyses.

To use this tutorial, you need to have ArcGIS installed with the Network Analyst extension and have the

tutorial data installed on a local or shared network drive on your system.

Tutorial data

Ask your system administrator for the correct path to the tutorial data if you do not find it at the default

installation path (C:\ArcGIS\ArcTutor\Network Analyst\Tutorial).

Network Analyst Tutorial

Exercise 1: Creating a network dataset

In this exercise, you will create a network dataset in a geodatabase using

San Francisco street and turn features. You will also include historical traffic

data so you can solve time-dependent routes.

Complexity:

Beginner

Data Requirement:

ArcGIS Tutorial Data Setup

Data Path:

C:\ArcGIS\ArcTutor\Network

Analyst\Tutorial\Exercise01

Goal:

To create a network dataset from a

streets feature class in a geodatabase

Creating a network dataset

Steps:

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

> ArcCatalog 10.

2. Enable the Network Analyst extension.

a. Click Customize > Extensions.

The Extensions dialog box opens.

b. Check Network Analyst .

c. Click Close .

3. On the Standard toolbar, click the Connect To Folder button .

The Connect to Folder dialog box opens.

4. Navigate to the folder with the ArcGIS Network Analyst tutorial data.

The default location for the tutorial data is C:\ArcGIS\ArcTutor\Network Analyst\Tutorial

5. Click OK .

A shortcut to the folder is added to the Catalog Tree under Folder Connections .

6. In the Catalog Tree , expand ...\ArcTutor\Network Analyst\Tutorial > Exercise01 >

SanFrancisco.gdb .

7. Click the Transportation feature dataset.

The feature classes the feature dataset contains are listed on the Contents tab of ArcCatalog.

8. Right-click the Transportation feature dataset and click New > Network Dataset .

Network Analyst Tutorial

The New Network Dataset wizard opens.

Note: To open the New Network Dataset wizard in a geodatabase, you

right-click the feature dataset that contains the source feature

classes (Streets, for example) and choose New > Network

Dataset . For a shapefile-based network dataset, you right-click the

Streets shapefile itself—not the workspace that contains the

shapefile—and choose New > Network Dataset.

The reason for the difference is that geodatabase networks allow

you to use multiple sources that are stored in the feature dataset

to create a multimodal network, while shapefile-based network

datasets are only capable of handling a single source feature

class.

9. Type Streets_ND for the name of the network dataset.

10. Click Next .

11. Check the Streets feature class to use it as a source for the network dataset.
