A flight route, a population density map, the Arctic, an app with a street map. Each of these jobs suits a different projection. Do you know which?
Answer 10 questions. In each one only one of four projections meets the job's requirement, such as keeping areas true or drawing the shortest route as a straight line. After every answer you get an explanation, and at the end you can review them all.
Ask the finder first: which projection should I use?No. Each job sets a different requirement, such as keeping areas true or drawing a route as a straight line, and a projection that is right for one usually fails at another. In every question only one of the 4 projections meets the job's requirement.
The correct answer is the pick of the projection finder for that job, and every wrong answer breaks the job's requirement. So the quiz, the finder and the “best projection for…” pages always agree.
The pool holds 17 jobs, and one round draws 10 of them.
