Mapping Glossary

The options available to you will depend on the type of map you are creating. 

Range Calculation Methods:

  • Natural Break
    Classes are based on natural groupings inherent in the data. Class breaks are identified that best group similar values and that maximize the differences between classes. Use this method if your data is unevenly distributed.
  • Quantiles
    Each class contains an equal number of features. A quantile classification is well suited to linearly distributed data. Quantile assigns the same number of data values to each class.
  • Equal Interval
    Equal intervals divide the range of attribute values into equal-sized subranges. Equal interval is best applied to familiar data ranges, such as percentages and temperature. This method emphasizes the amount of an attribute value relative to other values.
  • Standard Deviation
    Class breaks are placed above and below the mean value at intervals of 1, 0.5, or 0.25 standard deviations until all the data values are included in a class.

You can adjust the number of classes for the thematic map.

Colour Ramp
You can change the automatically applied range of colours used in the thematic map.

If you would prefer to set your own colours, you can manually adjust the HEX code. You can pick based on the colour itself or copy and past a HEX code into the box. RGB and CMYK colours can be converted to HEX codes using tools available on the web. Please see Changing the Primary Colour and Logo for more information. 

Font Family

Additional font types for map labels.

You can adjust the colour and width of the outline of each geography in the thematic map colour can be changed using a HEX code.

This allows you to add an additional layer of geography to your map, providing more context to your audience.

  • In the Level list, choose the level of geography to add as an overlay.
  • In the Colour box, adjust the colour as necessary. Again, this is a HEX code.
  • In the Width box, adjust the thickness of the border.

Overlay Label
This allows you to turn the labels on for your chosen Overlay layer.

  • In the Colour box, adjust as necessary (using the HEX code).
  • In the Font Size box, enter a size for the label font.
  • In the Halo box, adjust the colour of the halo effect. This puts a small outline around the text to better stand out on a busy background.
  • In the Halo Size box, adjust the thickness of the halo effect.

Use the slider to adjust the opacity of the thematic map in order to make it more or less opaque.
