Create Color-Coded Maps

See Navigating the Map for help on changing the map background, zooming in or out, printing, etc.

Creating a color-coded map provides information about an area of interest. To find out more about a market, you can quickly identify important patterns in the area you are investigating by viewing information about key metrics on a map. You can visually explore demographic information, consumer spending patterns, information about business or other market conditions on the map.

For the market area that you are exploring, you can select from a list of variables for a color-coded map illustrating the different range values of the chosen variable. You can choose the geographic level for the variable selected. For example, you can display information for Census block groups, ZIP Codes, counties, and other geographic levels. You can adjust the appearance of the map by changing color schemes, transparency levels, and ranges of the chosen variable.

  1. To access Create Color-Coded Maps, click the Research Market tab.
  2. Click Create Color-Coded Map.
  3. The Create Color-Coded Map pane appears.

    It is useful to select a location on the map. If you are looking within a specific location, enter the address in the Enter Address text box in the Create Color-Coded Map pane and click Go.

    The point appears on the map with a dialog box providing the address and options to move or delete the point.

    This dialog box can be minimized or closed using the buttons on the upper right of the dialog box.

    To access a closed dialog box for a point, place the pointer over the point and click.

Choose Variables

You can get more information about the area from the Choose Variables drop-down menu. Choose Variables provides a list of demographic variables such as population by age, sex, and race breakdowns as well as household and income information.

Note: The list of variables available is dependent on the subscription level. The premium subscription level provides the widest access to variables and can be mapped including consumer spending and Tapestry segmentation data.

  1. Click the Choose Variable drop-down menu in the Create Color-Coded Map pane.
  2. The Choose Variables dialog box appears.

    The list of available variables appears under Variables by Groups.

    You can scroll through the list to find the variable.

    You can also search from the variables.

  3. Type the words for the search in the Search text box.
  4. You can match the words in your search by clicking the Match all words check box.

  8. The map appears with the selected variable applied along with the geography level in the left corner of the color-coded map.

    Placing your pointer over an area of available geography within the map provides information in a pop-up.

    The Popular Variables column displays the most frequently used variables of all Business Analyst Online users. This allows you to discover variables other users find helpful. Once you have accessed the different variables, the Recently Viewed Variables columns will populate. This provides quick access to the variables you use most frequently.

  9. Click on the variable that you want to use from any of the three columns.
  10. The map appears with the selected variable applied along with the geography level in the left corner of the color-coded map.

Filter map options

You can filter the view of the map for the variable you have chosen. This allows you to highlight specific values visually on the map. For example, when viewing the population by age in a block group, you can create a filter by selecting greater than and enter a value of 5000. The map will only show color-shaded block groups when the population by age is more than 5000 people.

  1. In the Legend tab, under Filter map options, click the Choose one drop-down menu.
  2. You can choose from None, Greater than, Less than, and Equal to. None is the default.

  5. The map is automatically updated.

Color-Coded Data Tab

Using the Color-Coded Data tab, you can view the data in a table or graph. You can use the toggle button to view the variable values or percentages. This feature can also be used after the map has been created.

  1. In Map Detail, click the Color-Coded Data tab.

Auto selection is the default. You may override Auto Selection by choosing from any of the available geographies at a given scale.

Note: Small geographies are not available at all zoom levels. When zooming out, a pop-up appears to indicate that the selected geography cannot be viewed at this scale. You will need to zoom in to make the geography visible.

More Options

More Options allows you to edit features on the map. You can change the Method, Classes, Border thickness, and Border color.

To access More Options, click More Options.

The More Options dialog box appears.

Method

Quantile provides classes with the same number of features. This is useful for data that is evenly distributed and you want to emphasize the difference in relative position between features. For example, using the Quantile method to display Per Capita Income would result in an equal number of geographies in each class or value range.

The Equal Interval creates ranges (or classes) with equal spacing on the number line between the lowest and highest values of the variable. Equal Interval is useful when you want to emphasize the difference in values among geographies on the map. For example, using Equal Interval to display Per Capita Income would result in few geographies having the color of the highest class and more geographies would change to the color of the lower value range.

Manual allows you to define your classes, edit ranges and filter your map. You can change the classes in the More Options dialog box; however, use the Legend tab in Map Details to edits ranges and define the filter options. Create link to Map Details here.

In the More Options dialog box, click the Method drop-down menu and click your choice.

Classes

Classes allow you to select the number of classes that appears in the Legend in the Map Details. You can choose from 2, 3, 4, and 5. The default is 5.

In the More Options dialog box, click the Classes drop-down menu and click your choice.

Border thickness

Border thickness allows you to select the outline thickness of the selected geography. For example, if you've chosen Block Groups for your geography then the lines outlining your Block Groups will be the thickness selected in Border thickness. You can choose from 1, 2, 3, and 4. The default is 1.

In the More Options dialog box, click the Border thickness drop-down menu and click your choice.

Border color

Border color allows you to select the color outline of the selected geography. For example, if you've chosen Block Groups for your geography then the lines outlining your Block Groups will be the color selected in Border thickness. The default is black.

  1. In the More Options dialog box, click the Border color square and a drop-down menu appears for you to click your color choice.
  2. Click More Options to close the dialog box.
