Geocoding Tutorial

About the Geocoding tutorial

The ArcGIS Geocoding tutorial provides sample data and step-by-step instructions on how to use geocoding

functionality for matching addresses. This tutorial introduces you to geocoding with ArcGIS Desktop. You will

learn the basic techniques for creating address locators and geocoding with ArcGIS.

Some procedures in this tutorial require that you be familiar with using ArcCatalog and ArcMap. For example,

you should know how to copy data to a new location and add data to a map. You should also have a basic

understanding of what a geodatabase is and the objects it can contain. If you're new to GIS or feel you need to

refresh your knowledge, take some time to read What is ArcMap? and What is ArcCatalog? , or other related

topics in ArcGIS Help to help you understand many of these basic concepts.

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\Geocoding, as specified in the tutorial. Before you begin the exercises,

it is recommended that you make a copy of the data used in this tutorial so the original tutorial data will

remain unmodified. Copy the Atlanta.gdb folder in the ArcTutor\Geocoding folder to a new location on your

computer such as the C drive. The Atlanta.gdb folder contains a file geodatabase named Atlanta. Make sure

the geodatabase is not read-only.

Geocoding Tutorial

Exercise 1: Creating an address locator

In this tutorial you'll learn how to create a new address locator.

Complexity:

Beginner

Data Requirement:

ArcGIS Tutorial Data Setup

Data Path:

c:\ArcGIS\ArcTutor\Geocoding

Goal:

To create an address locator

An address locator lets you convert textual descriptions of locations into

geographic features. Address locators are stored and managed in a

workspace you choose. The workspace can be a file folder, file

geodatabase, personal geodatabase, or ArcSDE geodatabase. The first

thing you'll do is create an address locator based on your copy of the

Atlanta file geodatabase.

Steps:

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

2. Navigate to the Atlanta file geodatabase.

3. Right-click within the empty space of the Contents tab and click New > Address Locator .

The Create Address Locator dialog box appears.

4. Click the Browse button that is next to the Address Locator Style text box to open the Select

Address Locator Style dialog box.

Geocoding Tutorial

Choose the US Address—Dual Ranges address style and click OK .

5. Click the Browse button that is next to the Reference Data text box.

The Reference Data dialog box appears.

6. Navigate to the Atlanta file geodatabase, choose the streets feature class, then click Add .

You can also drag and drop the streets feature class from the workspace to the Reference Data

text box in the dialog box.

7. In the Create Address Locator dialog box, click the arrow under the Role column heading and

click Primary Table .

8. The Field Map section should be completed automatically. If not, choose the appropriate field in

the reference data for each address locator field.

Fields with an asterisk (*) next to their names are required by the address locator style. These

fields must be mapped with valid fields in the reference data. Nonrequired fields can be left as

<None> if the fields do not apply.

Next, you will set the output path for the locator.

9. Click the Browse button that is next to the Output Address Locator text box.

The Output Address Locator dialog box appears.

10. Navigate to the Atlanta geodatabase folder, type Atlanta in the Name text box, then click

Save .

The output path is displayed in the Create Address Locator dialog box.

11. Click OK to start the process of creating the address locator.
