In this lab, I learned how to create cartograms using the ScapeToad application. Cartograms are a method of displaying geospatial data as totals, where both color and area represent the values of the data. Additionally, I used ArcGIS Pro to visualize and classify the results of the cartogram. The main result of this lab includes two cartograms. The first cartogram shows the number of tweets worldwide recorded over a 2-hour period, while the second cartogram shows the number of tweets worldwide recorded over a 12-hour period.
The results of this lab are presented and discussed further down the page.
The first cartogram created using ScapeToad shows the amount of tweets created worldwide during a 2 hour period. The shape and size of the countries are calculated in relation to the number of tweets created in each country. To visualize the result, I used ArcGIS Pro, graduated symbols and performed the data classification with head/tail breaks. The result (see image above) shows a cartogram where the largest areas have the largest number of tweets in the whole world. The cartogram shows that the United States is the most active country on Twitter within the recorded time period, while counting the number of tweets within two hours.
The second cartogram created using ScapeToad shows the amount of tweets created worldwide during a 12 hour period. The cartogram shows, as in the first cartogram, that the United States is the most active country on Twitter within the recorded time period, while counting the number of tweets within 12 hours. However, there are some different results in this cartogram compared to the first one, where the number of tweets was counted over a two-hour period. When counted over a 12-hour period, the United Kingdom, Turkey, and the Philippines (in the third class) generate more tweets than in the second class. But during the two-hour period, these countries were categorized in the second class.
