There are two interesting things going on with this app.
● 1) the resulting heat map looks completely different depending on each person’s ideas set into the app’s categories.
● 2) the resulting heat map would point precisely to the TC, if a person’s ideas matched with what ff has interpreted, even if a clue’s answer did not have a geographical feature from known sources, as long as the person has also defined geographical features themselves that matched their ideas.
Also you can save your heat map to a spreadsheet for further investigation.
