Analyzing hurricanes using Tracking Analyst

Hurricanes from the Atlantic Ocean pose an enormous threat to populations

in the southeastern United States. Scientists continue to study hurricane

patterns in an attempt to learn more about the environmental factors that

influence their paths. This guidebook will show you how ArcGIS Tracking

Analyst can be used to analyze the movement of hurricanes in the Atlantic

Ocean. The data used in this guidebook was collected for hurricane

positions in the Atlantic Ocean in 2000.

Complexity:

Beginner

Data Requirement:

Installed with software

Data Path:

C:\argis\ArcTutor\Tracking_Analyst

Goal:

To learn some basic Tracking Analyst

functionality by analyzing hurricane

patterns in the Atlantic Ocean

Adding hurricane data to a map

To get started in this guidebook, a map document has already been created for you. Follow the steps below

to open the map document and load hurricane data into Tracking Analyst.

Prerequisite:

Before you begin this guidebook, make sure that the Tracking Analyst extension has been turned on and the

Tracking Analyst toolbar has been added in ArcMap.

Learn how to configure the Tracking Analyst environment .

Steps:

1. Start ArcMap and open the hurricanes2000.mxd file from the

C:\arcgis\ArcTutor\Tracking_Analyst folder.

2. Click the Add Temporal Data button on the Tracking Analyst toolbar to open the Add

Temporal Data Wizard dialog box.

3. Leave the Storage policy drop-down set to the default value. Also, leave the next button set to

the default option of A feature class or shapefile containing temporal data . This indicates that

the data you want to load is simple tracking data and is contained in a single feature class or

shapefile. Selecting the second button would indicate that you want to load complex tracking

data contained in two separate tables.

4. Click the Open button and browse to the feature class called atlantic_hurricanes_2000 in a

geodatabase called Hurricanes in C:\arcgis\ArcTutor\Tracking_Analyst\Simple .

5. Click the Choose the field containing the date/time drop-down arrow and click the field called

Date_Time to select it. This tells Tracking Analyst to look in this field to find information about

when each event happened. A label of [Date] appears next to the drop-down menu, indicating

that the field has a data type of Date. Tracking Analyst automatically knows how to extract the

date and time information from fields of this type.

It is also possible to select a text or numeric field containing the date and time information. In

those cases, some additional steps would need to be followed to tell Tracking Analyst how to

parse the date and time from the values contained in the text field.

6. Leave the time zone set to the default of Greenwich Mean Time in the drop-down menu

containing time zones. Uncheck the Values are adjusted for daylight savings check box.

These settings indicate to Tracking Analyst that this data was collected in Greenwich Mean Time

without any daylight savings adjustment.

7. Click the arrow on the next drop-down menu and click the field called EVENTID to select it. This

tells Tracking Analyst how to organize the data into tracks. In this case, the EVENTID field

contains the hurricane name for each event. Each individual hurricane's path will become a track

in Tracking Analyst.

If you have tracking data that cannot be organized into tracks, <None> can be selected to

indicate that the data contains no tracks. This will make some options designed to symbolize

tracks less meaningful. Essentially, Tracking Analyst will handle each individual event as a

separate track.

8. Leave the rest of the Add Temporal Data Wizard dialog box set to the default settings. Confirm

that your dialog box looks like the one below and click Next to proceed.

9. The next step in the Add Temporal Data Wizard dialog box gives you the ability to import only a

subset of the data contained in a feature class by clicking the Query Builder button. In this case,

you want to import the entire feature class, so click Finish to complete the wizard and add the

data to your map.

10. A new tracking layer called atlantic_hurricanes_2000 now appears in the table of contents with

a default symbol. Right-click the layer and click Zoom to Layer to make your map zoom to the

extent of the new tracking layer. Your map should now look like the image below.
