This Virtual Online Classify experience has led you through thematic classification, showing real world applications, summarised as:

• The concept of thematic classification and the reasoning behind grouping data into classes.

• The determination of class intervals and class boundaries.
  

• Classification techniques to ensure the geographical pattern of the distribution is optimally portrayed to reveal the thematic implications.

• How the number of classes can be influenced by whether a greyscale or chromatic tonal values are used to display the choropleth map.

You should be able to:

• understand why data needs to be grouped and formed into classes.
• determine the class intervals and subsequent boundaries from a given set of data. Further, you should be able to conclude which classification technique best suits the data to optimally display the geographic pattern.
• appreciate the virtues of either grey scale or chromatic tonal values in the depiction of the resulting choropleth map.
