Exercise 6: Creating simple ring trade areas and a spatial overlay

You can create trade areas for the nationwide business locations that you have created and append demographic data.

步骤:

1. Click Business Analyst on the toolbar and click Trade Area.
2. On the Trade Area Wizard dialog box, click the Create New Trade Area button and click Next.
3. On the Trade Area Wizard dialog box, click the Simple Rings button and click Next.
4. On the Trade Area Wizard dialog box, click the Which layer contains your stores? drop-down menu and select Trader_Joes.
5. Select LOCNUM in the Which field contains the store ID? drop-down menu.
6. Click the All stores button for How many stores do you want to use? and click Next.
7. On the Trade Area Wizard dialog box, click the 1 button, type 5 for the ring value and click Next.
8. On the Trade Area Wizard dialog box, type Trader Joe's 5 mile rings in the What do you want to name the new Trade Area? text box and click Finish.

   The 5-mile simple ring trade areas are created around each of the business locations and define equal-sized markets around each site.

   The 5-mile distance is typical of the distance a customer would travel to each local store. The polygons allow easy benchmarking between store locations nationwide. For example, you can compare each of the stores to determine which has the highest population within 5 miles or which has the lowest diversity. This is important when you analyze why certain stores perform better than others. To view these demographics, you will append the data to each of the ring locations.

9. Click the Business Analyst window button.
The Business Analyst window appears.
10. Click the Append Data (Spatial Overlay) button in the Favorites section.

    This is a shortcut to access tools through the Business Analyst menu.

11. On the Append Data (Spatial Overlay) dialog box, click the Input Data Layer button and select Standard Business Analyst Data in the drop-down menu. Select Trader Joe's five mile rings in the Overlay Layer drop-down menu and click Next.
12. On the Append Data (Spatial Overlay) dialog box, highlight the following categories under the Select one or more fields you want to use section and click the single right arrow to move it to the right column.
    • <current year> Race and Hispanic Origin (Esri)
